Dave Zeiger: /* TriloBoat Superstructure Rules-of-Thumb */ Extend FRACTIONAL rule

{{ToolTemplate2|ToolParent=Open Source Boat|ToolName=TriloBoat}}

[[Image:T32x8 CARGO Sample.jpg|thumb|center|600px|'''Sample TriloBoat Instance: T32x8 with typical cargo layout.''']]

== '''TriloBoat Overview''' ==

TriloBoats were designed by myself ([[Dave Zeiger]]) as a formula generated class of box barge (or scow) hulls based on construction from sheet materials.

The rules-of-thumb generate hundreds of instances in a wide array of sizes and functional layouts. Potential layouts include kayak, skiff, cargo carrier, landing craft, tug, ferry, houseboat, cruiser and multihull. They are compatible with sail and power. Appropriately designed, built and handled, TriloBoats are seaworthy across a wide range of conditions.

The rules-of-thumb are selected to simplify construction for dramatic savings in time, energy, material and money. This allows general construction by persons with very modest skills, with minimal resources and infrastructure.

I offer the TriloBoat concept as a candidate (subject to open source development) for [[Open Source Boat]] and [[Boat]].

My partner, Anke Wagner, and I have built three instances of TriloBoat, to date, including S/V SLACKTIDE, our home for the last three years. For further information, discussion, construction and sailing photos, please visit http://www.triloboats.com, and http://triloboats.blogspot.com.

== Detailed Description ==

The following is the ''[[TriloBoat]] Design Formula'', expressed as rules-of-thumb and guidelines. Taken together, they generate a class of box barge hulls. By converting generalities to specifics within these guidelines, produces one instance among thousands of possibilities.

Note that these rules develop design lines, only. Construction details are dependent on materials and methods used. Appropriate marine construction standards should be followed in the fabrication and assembly process.

=== '''TriloBoat Hull Rules-of-Thumb''' ===

* Hulls are simple, box barges - rectangular in plan and section views.

* Hulls are constructed from whole and simple-fraction multiples of rectangular, off-the-shelf, sheet materials. Where possible, straight-line cuts that parallel one edge are preferred.

* Hull beam is one sheet.

* Hull length is scalable, generally in multiples (or combinations) of full length sheets.

* Hull curves are limited to the bottom ends (generally one quarter the LengthOfHull each, curved in profile view) , reducing lofting, layout, spiling, cutting, beveling and bending to bare minimums.

* Hull curves are separated by a bottom dead-flat (planar section of bottom, generally one half the LengthOfHull).

* Hulls are jigless, and self-rectifying (consequence of these rules).

* All controlling numbers are rationalized (rounded), where possible, to maximize mnemonic retention, communication and accuracy.

=== '''TriloBoat Superstructure Rules-of-Thumb''' ===

* Superstructures are constructed from whole and simple-fraction multiples of rectangular, off-the-shelf, sheet materials. Where possible, straight-line cuts that parallel one edge are preferred.

* Side decks are not used (flush decks maximize strength, simplify construction and assist ventilation).

* All decks are planar (sloped to drain), pitched or section-of-cylinder (simple layout and construction).

* Where section-of-cylinder decks are used, upper hull or superstructure are canted inboard to provide slack for a single sheet span of desired crown.

* All controlling numbers are rationalized (rounded), where possible, to maximize mnemonic retention, communication and accuracy.''

=== '''TriloBoat Trade-Offs (Opposing Values)''' ===

* As one cuts away from the original ''prism'' (the rectangular slab formed by ''length'' x ''beam'' x ''draft''), one improves efficiency through the water (by reducing drag), but reduces interior volume and displacement.

* Narrow-for-length is faster through the water. Wide-for-length is slower, but more commodious and hauls more cargo for its length. I shoot for a length to beam ratio of 4:1, and compromise away in either direction, as needed.

* High end curves meet waves better, but reduce flat-water speed, displacement/buoyancy and interior volume.

* Every partial sheet generates lofting, cut-out and waste, but increases options. Simple fractions of sheets yielding round numbers (1, 1/2, 1/3, 1/4, 1/6, 1/8) generate less waste, and make for simple layout. Consider design for whole sheets where possible, and larger fractions where not.

* Curves take time, but add rigidity and reduce hull resistance, and in the superstructure shed water, add headroom and aesthetics. Consider using them sparingly where their benefits outweigh costs.

=== '''TriloBoat Suggested Features''' ===

* Hull Divisions - 1/4 LengthOverAll as bow curve, 1/2 LengthOverAll as dead-flat (no bottom curve in profile view), and 1/4 LengthOverAll as aft curve. This allows easy end-curves while generating fully rectilinear mid-ships (simplifying construction of the interior and enabling modular furnishings), and allows easy blocking and transport by flat-bed.

* Locate a bulkhead at the division between dead-flat and end curve to simplify bending the bottom planking. Other bulkheads may be recommended along the hull length, depending on length and use.

* Box girder furnishings in the interior do much to stiffen the hull, and particularly the bottom.

* Plywood sheet construction with dimensional lumber framing (glued and nailed) is the fastest wood construction method. Sawn chine logs (from wide planks) at bow and stern are faster than bending, and require no steaming.

* External appendages (e.g., rudder, off-centerboards, skegs) avoid complicated and hull-weakening housings, wells and trunks. Much easier to dismount, inspect, maintain, modify and repurpose.

* Junk Rig - Easy to build, maintain and operate with short-handed crews. Low stress and fail safer. Minimal standing rigging. Flat cut sails require only rudimentary lofting and design. May use GVCS bioplastic fabric.

=== '''Notes''' ===

* All 'rules' may be altered or ignored by end-users. Each deviation, however, costs in time, material and efficiency. End-users are advised to consider cost/benefit returns for each departure.

* The relation between end curves and dead-flat is determined by use. One extreme, no end curves and all dead-flat, produces a dock-like hull. The other extreme, all curve and no dead-flat produces a constant 'rockered' bottom (easiest to move through water, but requires more time to build, generates more waste and reduces displacement and interior volume.

* The height of end curves is determined by intended use. High end curves clear more waves, especially at the bow, and are suitable for sailing hulls (which heel) or any hulls intended for use in unprotected waters. Lower end curves increase buoyancy and interior volume, and may be suitable for protected waters. A low or flat curve aft is consistent with planing hulls. There's a bit more to this that needs to be developed as an info module.

* Imperial System is recommended, unfortunately, unless using metric dimensioned sheets. This has to do with world standards for sheet dimensions generally being based on Imperial ''feet''. Metric translations produce lengthy, non-mnemonic numbers which lead to miscommunication and error.

* The ''feet-inches-eighths system'' (a common standard in boat-building) helps simplify Imperial.

* Plywood sheets were the original inspiration, but the method is adaptable to any sheet material with maritime properties, such as steel and aluminum. Ply sheets are readily available in 4 x 8, 10, 12, 16 and 20 foot lengths (easy beam choices), though 4x8ft sheets are standard and the most economical. We've found select, AC grade to be sufficient.

* Consider composite sheet construction incorporating closed cell, insulating foam for vessels intended as [[Housing]]. SIP (Structural Insulated Panel) technologies are easily adaptable to Triloboat construction, and are recommended where insulation is desired.

== Product Ecology ==

=== From ===

A [[TriloBoat]] is assembled from sheet materials which include wood, wood composites, (bio)plastic composites, steel or aluminum. Each material may involve a different toolset, and can benefit from production by tools from the GVCS.

Wood based construction might thus involve the [[Dimensional Sawmill]]. Metal based construction might involve [[Open Source Welder]] and [[Metal Roller]]. Composite contruction might involve the [[Bioplastic Extruder]] and/or [[Chipper]]. The [[Plasma Cutter]] or [[Laser Cutter]] might be involved in fleet construction.

=== Uses ===

Hardware, propulsion electronics, gear, outfit and accessories vary from extremely simple/minimal to highly advanced, and may use one to several tools from the GVCS.

For example, a pure sailing vessel need use no further tools from the GVCS.

In contrst, a landing-craft layout might arrange propulsion using the [[Heat Exchanger]] to power the [[Modern Steam Engine]] to turn a prop on the [[Universal Rotor]]. [[Hydraulic Motors]] might be used for propulsion, an anchor winch, various PTO (Power Take Off) tasks, or a modified [[Backhoe]] as a loading crane. The [[Nickle-Iron Battery]] to power shipboard electronics. A [[LifeTrac III]] might be carried to enhance longshoring capabilities. If steel, it might carry the [[Welder]] as part of its essential gear.

=== Creates ===

[[Transportation]] and/or [[Housing]].

=== Enables ===

The [[Truck]] and [[Car]] are enabled, in the sense that their range is extended to isolated road systems which are accessible by water.

In a similar sense, the entire GVCS is potentially able to become mobile, allowing the sharing of tools or tool ecologies among communities close to water. The [[Truck]] has some capability for this, but is limited by the need for roads and has a relatively small, energy expensive payload.

== Status ==

The ''TriloBoat Design Formula'' is fully developed, many instances have been designed, and several vessels built and more or less intensively field tested.

=== TriloBoat Concept Development ===

To be completed:

* TriloBoat's adaptation to the OSE platform and standards.
* Designation and cross-linking as [[Open Source Boat]] and/or [[Boat]]?
* Exposure to Open Source Development?

=== TriloBoat User Manual ===

To be developed:

* Guidelines for Adaptation to particular purposes and needs.
* Guidelines for Scantlings for various material suites and construction methods.
* Guidelines for Construction Methods and Techniques for various material suites.
* Guidelines for Sail Rig options and design.
* Guidelines for Power Propulsion options and design.
* Guidelines for GVCS and other tool ecologies.
* Open Portfolio of Gear and Outfit options.

=== Bill of Materials and Manufacturing Instructions ===

Yet to be developed is an Open Portfolio of Plans for representative Instances, each meeting a general configuration of [Boat], but focused on a particular use (e.g., Landing Craft).

Each Plan would be developed from the above as per GVCS usual, once the rules generating them have stabilized in the OSD process. In effect, the TriloBoat rules and guidelines jumpstart the research and development required for each Plan.

Each Plan would be comprised of a ''Bill of Materials and Manufacturing Instructions'' for a scalable product, in the normal, GVCS format.

Unlike other tools in the GVCS, the Portfolio will contain several [OSBoats], and remain Open (may be added to as new products are developed (e.g., landing-craft, cargo carrier, tug, etc.).

=== Associated Tasks ===

The following, associated materials are presently available in fully adequate form external to OSE, but may eventually be brought into OS development?

* Safety Standards for materials and methods used.
* Marine Training materials for end-users.

Dave Zeiger: /* Introducing Myself (Dave Zeiger) */ Add YouTube to intro

== Introducing Myself ([[Dave Zeiger]]) ==

Hi Folks,

I'm the originator of the TriloBoat concept, which I've offered up for OSDevelopment.

I took the wiki instructions to heart and did a 'braindump' on the content page. I realize that it needs to be deeply edited to bring it into conformity with OSE and general wiki format. Please excuse my gaffes.

Due to time and access restrictions (we're about to sail off the edge, again), I won't be able to participate often or at length. I will, however, check in as often as I can.

If you have any particular questions I can help with, please visit my site at http://www.triloboats.com or blog at http://triloboats.blogspot.com, where I have a lot of information posted, or write me at ''triloboats AT gmail DOT com''. I'll be sailing, and slow getting back to you, but unless overwhelmed by volume, will eventually write back.

[[Dave Zeiger]]

PS. Here is a video from my Team Culture Bio, showing a few TriloBoat configurations:

== Enabling the TriloBoat Approach vs Product ==

I note that TriloBoat (any ''Boat'', for that matter) will be an unusual project within the OSE, with many more variables than is usual in product development. This won't be a case of zeroing in on a design for a single, modular tool.

''(OR, if it IS decided to BE a single product approach, the rule set can be further constrained... focus on hull only, make ends uniform (limited to a single sheet), and only scale by beam and adding sheets to lengthen or shorten... this, however, severely limits adaptability, and is a relatively trivial result... this might, however, be the core product design within a larger design portfolio.)''

The Bill of Materials and Builder's Instructions, for example, are going to be very different if using steel vs plywood vs composite construction, as will portions of the User's Manual. A landing craft will have wildly different requirements than a sailing coaster or skiff. Being more approach than product, it's going to take some special handling.

I'd suggest that the OSD process re TriloBoat orient itself from the outset toward enabling end-users to follow a number of paths through the TriloBoat 'design space' as well as the subsequent build.

Design guidelines, various material suites with associated construction techniques and methods, layout and outfit options - the ''erector set'' approach - will be much more versatile than any given plan or set of plans.

That being said, a portfolio of product-level designs for various configurations will be useful, and sufficient for most end-users - each design similar to the standard OSE product, and all under the header of [[Boat]]

[[Dave Zeiger]]

== TriloBoat Design Decision Tree? ==

[[Boat]] concept strikes me as a bit unusual within the GVCS, in that it is scalable and adaptable to a far wider degree than, say, the [[Truck]] or [[Car]].

Decisions that will go into a [[Boat]] include materials, method, size, intended conditions (eg, protected vs open waters), intended purpose, and propulsion methods. It will be outfitted with a far wider range of tools, and can be 'packaged' with other tools to a far greater degree.

TriloBoat narrows the range considerably by rules-of-thumb constraining shape, but still generates a class of thousands of instances. By the time even GVCS options are factored in, the class is... um... freaking ''huge!''

I propose that a Design Decision Tree be given OS consideration, as a means of navigating the ''class'' of TriloBoats, to assist arrival at an ''instance'' of TriloBoat.

Questions include:

* Do we want to spend time/energy on this?
* How to prioritize the tree?
* How to represent the tree?
* Can navigating the tree be computer assisted?
* How best to integrate the tree with other materials?
* Can this approach be generalized to work with other OS development?

{{ToolTemplate2|ToolParent=Open Source Boat|ToolName=TriloBoat}}

[[Image:T32x8 CARGO Sample.jpg|thumb|center|600px|'''Sample TriloBoat Instance: T32x8 with typical cargo layout.''']]

== '''TriloBoat Overview''' ==

TriloBoats were designed by myself ([Dave Zeiger]) as a formula generated class of box barge (or scow) hulls based on construction from sheet materials.

The rules-of-thumb generate hundreds of instances in a wide array of sizes and functional layouts. Potential layouts include kayak, skiff, cargo carrier, landing craft, tug, ferry, houseboat, cruiser and multihull. They are compatible with sail and power. Appropriately designed, built and handled, TriloBoats are seaworthy across a wide range of conditions.

The rules-of-thumb are selected to simplify construction for dramatic savings in time, energy, material and money. This allows general construction by persons with very modest skills, with minimal resources and infrastructure.

I offer the TriloBoat concept as a candidate (subject to open source development) for [[Open Source Boat]] and [[Boat]].

My partner, Anke Wagner, and I have built three instances of TriloBoat, to date, including S/V SLACKTIDE, our home for the last three years. For further information, discussion, construction and sailing photos, please visit http://www.triloboats.com, and http://triloboats.blogspot.com.

== Detailed Description ==

The following is the ''[[TriloBoat]] Design Formula'', expressed as rules-of-thumb and guidelines. Taken together, they generate a class of box barge hulls. By converting generalities to specifics within these guidelines, produces one instance among thousands of possibilities.

Note that these rules develop design lines, only. Construction details are dependent on materials and methods used. Appropriate marine construction standards should be followed in the fabrication and assembly process.

=== '''TriloBoat Hull Rules-of-Thumb''' ===

* Hulls are simple, box barges - rectangular in plan and section views.

* Hulls are constructed from whole and simple-fraction multiples of rectangular, off-the-shelf, sheet materials.

* Hull beam is one sheet.

* Hull length is scalable, generally in multiples (or combinations) of full length sheets.

* Hull curves are limited to the bottom ends (generally one quarter the LengthOfHull, curved in profile view) , reducing lofting, layout, spiling, cutting, beveling and bending to bare minimums.

* Hull curves are separated by a bottom dead-flat (planar section of bottom, generally one half the LengthOfHull).

* Hulls are self-rectifying and jig-less (consequences of these rules).

* All controlling numbers are rationalized (rounded), where possible, to maximize mnemonic retention, communication and accuracy.

=== '''TriloBoat Superstructure Rules-of-Thumb''' ===

* Superstructures are constructed from whole and simple-fraction multiples of rectangular, off-the-shelf, sheet materials.

* Side decks are not used (flush decks maximize strength, simplify construction and assist ventilation).

* All decks are planar (sloped to drain), pitched or section-of-cylinder (simple layout and construction).

* Where section-of-cylinder decks are used, upper hull or superstructure are canted inboard to provide slack for a single sheet span of desired crown.

* All controlling numbers are rationalized (rounded), where possible, to maximize mnemonic retention, communication and accuracy.''

=== '''TriloBoat Trade-Offs (Opposing Values)''' ===

* As one cuts away from the original ''prism'' (the rectangular slab formed by ''length'' x ''beam'' x ''draft''), one improves efficiency through the water (by reducing drag), but reduces interior volume and displacement.

* Narrow-for-length is faster through the water. Wide-for-length is slower, but more commodious and hauls more cargo for its length. I shoot for a length to beam ratio of 4:1, and compromise away in either direction, as needed.

* High end curves meet waves better, but reduce flat-water speed, displacement/buoyancy and interior volume.

* Every partial sheet generates lofting, cut-out and waste, but increases options. Simple fractions of sheets yielding round numbers (1, 1/2, 1/3, 1/4, 1/6, 1/8) generate less waste, and make for simple layout. Consider design for whole sheets where possible, and larger fractions where not.

* Curves take time, but add rigidity and reduce hull resistance, and in the superstructure shed water, add headroom and aesthetics. Consider using them sparingly where their benefits outweigh costs.

=== '''TriloBoat Suggested Features''' ===

* Hull Divisions - 1/4 LengthOverAll as bow curve, 1/2 LengthOverAll as dead-flat (no bottom curve in profile view), and 1/4 LengthOverAll as aft curve. This allows easy end-curves while generating fully rectilinear mid-ships (simplifying construction of the interior and enabling modular furnishings), and allows easy blocking and transport by flat-bed.

* Locate a bulkhead at the division between dead-flat and end curve to simplify bending the bottom planking. Other bulkheads may be recommended along the hull length, depending on length and use.

* Box girder furnishings in the interior do much to stiffen the hull, and particularly the bottom.

* Plywood sheet construction with dimensional lumber framing (glued and nailed) is the fastest wood construction method. Sawn chine logs (from wide planks) at bow and stern are faster than bending, and require no steaming.

* External appendages (e.g., rudder, off-centerboards, skegs) avoid complicated and hull-weakening housings, wells and trunks. Much easier to dismount, inspect, maintain, modify and repurpose.

* Junk Rig - Easy to build, maintain and operate with short-handed crews. Low stress and fail safer. Minimal standing rigging. Flat cut sails require only rudimentary lofting and design. May use GVCS bioplastic fabric.

=== '''Notes''' ===

* All 'rules' may be altered or ignored by end-users. Each deviation, however, costs in time, material and efficiency. End-users are advised to consider cost/benefit returns for each departure.

* The relation between end curves and dead-flat is determined by use. One extreme, no end curves and all dead-flat, produces a dock-like hull. The other extreme, all curve and no dead-flat produces a constant 'rockered' bottom (easiest to move through water, but requires more time to build, generates more waste and reduces displacement and interior volume.

* The height of end curves is determined by intended use. High end curves clear more waves, especially at the bow, and are suitable for sailing hulls (which heel) or any hulls intended for use in unprotected waters. Lower end curves increase buoyancy and interior volume, and may be suitable for protected waters. A low or flat curve aft is consistent with planing hulls. There's a bit more to this that needs to be developed as an info module.

* Imperial System is recommended, unfortunately, unless using metric dimensioned sheets. This has to do with world standards for sheet dimensions generally being based on Imperial ''feet''. Metric translations produce lengthy, non-mnemonic numbers which lead to miscommunication and error.

* The ''feet-inches-eighths system'' (a common standard in boat-building) helps simplify Imperial.

* Plywood sheets were the original inspiration, but the method is adaptable to any sheet material with maritime properties, such as steel and aluminum. Ply sheets are readily available in 4 x 8, 10, 12, 16 and 20 foot lengths (easy beam choices), though 4x8ft sheets are standard and the most economical. We've found select, AC grade to be sufficient.

* Consider composite sheet construction incorporating closed cell, insulating foam for vessels intended as [[Housing]]. SIP (Structural Insulated Panel) technologies are easily adaptable to Triloboat construction, and are recommended where insulation is desired.

== Product Ecology ==

=== From ===

A [[TriloBoat]] is assembled from sheet materials which include wood, wood composites, (bio)plastic composites, steel or aluminum. Each material may involve a different toolset, and can benefit from production by tools from the GVCS.

Wood based construction might thus involve the [[Dimensional Sawmill]]. Metal based construction might involve [[Open Source Welder]] and [[Metal Roller]]. Composite contruction might involve the [[Bioplastic Extruder]] and/or [[Chipper]]. The [[Plasma Cutter]] or [[Laser Cutter]] might be involved in fleet construction.

=== Uses ===

Hardware, propulsion electronics, gear, outfit and accessories vary from extremely simple/minimal to highly advanced, and may use one to several tools from the GVCS.

For example, a pure sailing vessel need use no further tools from the GVCS.

In contrst, a landing-craft layout might arrange propulsion using the [[Heat Exchanger]] to power the [[Modern Steam Engine]] to turn a prop on the [[Universal Rotor]]. [[Hydraulic Motors]] might be used for propulsion, an anchor winch, various PTO (Power Take Off) tasks, or a modified [[Backhoe]] as a loading crane. The [[Nickle-Iron Battery]] to power shipboard electronics. A [[LifeTrac III]] might be carried to enhance longshoring capabilities. If steel, it might carry the [[Welder]] as part of its essential gear.

=== Creates ===

[[Transportation]] and/or [[Housing]].

=== Enables ===

The [[Truck]] and [[Car]] are enabled, in the sense that their range is extended to isolated road systems which are accessible by water.

In a similar sense, the entire GVCS is potentially able to become mobile, allowing the sharing of tools or tool ecologies among communities close to water. The [[Truck]] has some capability for this, but is limited by the need for roads and has a relatively small, energy expensive payload.

== Status ==

The ''TriloBoat Design Formula'' is fully developed, many instances have been designed, and several vessels built and more or less intensively field tested.

=== TriloBoat Concept Development ===

To be completed:

* TriloBoat's adaptation to the OSE platform and standards.
* Designation and cross-linking as [[Open Source Boat]] and/or [[Boat]]?
* Exposure to Open Source Development?

=== TriloBoat User Manual ===

To be developed:

* Guidelines for Adaptation to particular purposes and needs.
* Guidelines for Scantlings for various material suites and construction methods.
* Guidelines for Construction Methods and Techniques for various material suites.
* Guidelines for Sail Rig options and design.
* Guidelines for Power Propulsion options and design.
* Guidelines for GVCS and other tool ecologies.
* Open Portfolio of Gear and Outfit options.

=== Bill of Materials and Manufacturing Instructions ===

Yet to be developed is an Open Portfolio of Plans for representative Instances, each meeting a general configuration of [Boat], but focused on a particular use (e.g., Landing Craft).

Each Plan would be developed from the above as per GVCS usual, once the rules generating them have stabilized in the OSD process. In effect, the TriloBoat rules and guidelines jumpstart the research and development required for each Plan.

* The height of end curves is determined by intended use. High end curves clear more waves, especially at the bow, and are suitable for sailing hulls (which heel) or any hulls intended for use in unprotected waters. Lower end curves increase buoyancy and interior volume, and may be suitable for protected waters. A low or flat curve aft is consistent with planing hulls. There's a bit more to this that needs to be developed as an info module.

* Imperial System is recommended, unfortunately, unless using metric dimensioned sheets. This has to do with world standards for sheet dimensions generally being based on Imperial ''feet''. Metric translations produce lengthy, non-mnemonic numbers which lead to miscommunication and error.

* The ''feet-inches-eighths system'' (a common standard in boat-building) helps simplify Imperial.

* Plywood sheets were the original inspiration, but the method is adaptable to any sheet material with maritime properties, such as steel and aluminum. Ply sheets are readily available in 4 x 8, 10, 12, 16 and 20 foot lengths (easy beam choices), though 4x8ft sheets are standard and the most economical. We've found select, AC grade to be sufficient.

* Consider composite sheet construction incorporating closed cell, insulating foam for vessels intended as [[Housing]]. SIP (Structural Insulated Panel) technologies are easily adaptable to Triloboat construction, and are recommended where insulation is desired.

== Product Ecology ==

=== From ===

A [[TriloBoat]] is assembled from sheet materials which include wood, wood composites, (bio)plastic composites, steel or aluminum. Each material may involve a different toolset, and can benefit from production by tools from the GVCS.

Wood based construction might thus involve the [[Dimensional Sawmill]]. Metal based construction might involve [[Open Source Welder]] and [[Metal Roller]]. Composite contruction might involve the [[Bioplastic Extruder]] and/or [[Chipper]]. The [[Plasma Cutter]] or [[Laser Cutter]] might be involved in fleet construction.

=== Uses ===

Hardware, propulsion electronics, gear, outfit and accessories vary from extremely simple/minimal to highly advanced, and may use one to several tools from the GVCS.

For example, a landing-craft layout might use the [[Heat Exchanger]] to power the [[Modern Steam Engine]] to turn the [[Universal Rotor]]. [[Hydraulic Motors]] might be used for various PTO (Power Take Off) tasks, or run a modified [[Backhoe]] as a loading crane. The [[Nickle-Iron Battery]] to power shipboard electronics. A [[LifeTrac III]] might be carried to enhance longshoring capabilities.

=== Creates ===

[[Transportation]] and/or [[Housing]].

=== Enables ===

The [[Truck]] and [[Car]] are enabled, in the sense that their range is extended to isolated road systems which are accessible by water.

In a similar sense, the entire GVCS is potentially able to become mobile, allowing the sharing of tools or tool ecologies among communities close to water. The [[Truck]] has some capability for this, but is limited by the need for roads and has a relatively small, energy expensive payload.

== Status ==

The ''TriloBoat Design Formula'' is fully developed, many instances have been designed, and several vessels built and more or less intensively field tested.

=== TriloBoat Concept Development ===

To be completed:

* TriloBoat's adaptation to the OSE platform and standards.
* Designation and cross-linking as [[Open Source Boat]] and/or [[Boat]]?
* Exposure to Open Source Development?

=== TriloBoat User Manual ===

To be developed:

* Guidelines for Adaptation to particular purposes and needs.
* Guidelines for Scantlings for various material suites and construction methods.
* Guidelines for Construction Methods and Techniques for various material suites.
* Guidelines for Sail Rig options and design.
* Guidelines for Power Propulsion options and design.
* Guidelines for GVCS and other tool ecologies.
* Open Portfolio of Gear and Outfit options.

=== Bill of Materials and Manufacturing Instructions ===

Yet to be developed is an Open Portfolio of Plans for representative Instances, each meeting a general configuration of [Boat], but focused on a particular use (e.g., Landing Craft).

Each Plan would be developed from the above as per GVCS usual, once the rules generating them have stabilized in the OSD process. In effect, the TriloBoat rules and guidelines jumpstart the research and development required for each Plan.

Each Plan would be comprised of a ''Bill of Materials and Manufacturing Instructions'' for a scalable product, in the normal, GVCS format.

Unlike other tools in the GVCS, the Portfolio will contain several [OSBoats], and remain Open (may be added to as new products are developed (e.g., landing-craft, cargo carrier, tug, etc.).

=== Associated Tasks ===

The following, associated materials are presently available in fully adequate form external to OSE, but may eventually be brought into OS development?

* Safety Standards for materials and methods used.
* Marine Training materials for end-users.

Dave Zeiger: /* TriloBoat Suggested Features */ typos

{{ToolTemplate2|ToolParent=Open Source Boat|ToolName=TriloBoat}}

[[Image:T32x8 CARGO Sample.jpg|thumb|center|600px|'''Sample TriloBoat Instance: T32x8 with typical cargo layout.''']]

== '''TriloBoat Overview''' ==

TriloBoats were designed by myself (Dave Zeiger) as a formula generated class of box barge (or scow) hulls based on construction from sheet materials.

The rules-of-thumb generate hundreds of instances in a wide array of sizes and functional layouts. Potential layouts include kayak, skiff, cargo carrier, landing craft, tug, ferry, houseboat, cruiser and multihull. They are compatible with sail and power. Appropriately designed, built and handled, are seaworthy across a wide range of conditions.

The rules-of-thumb are selected to simplify construction for dramatic savings in time, energy, material and money. This allows general construction by persons with very modest skills, with minimal resources and infrastructure.

I offer the TriloBoat concept as a candidate (subject to open source development) for [[Open Source Boat]] and [[Boat]].

My partner, Anke Wagner, and I have built three instances of TriloBoat, to date, including S/V SLACKTIDE, their home for the last three years. For further information, discussion, construction and sailing photos, please visit http://www.triloboats.com, and http://triloboats.blogspot.com.

== Detailed Description ==

The following is the ''[[TriloBoat]] Design Formula'', expressed as rules-of-thumb and guidelines. Taken together, they generate a class of box barge hulls. By converting generalities to specifics within these guidelines, produces one instance among thousands of possibilities.

Note that these rules develop design lines, only. Construction details are dependent on materials and methods used. Appropriate marine construction standards should be followed in the fabrication and assembly process.

=== '''TriloBoat Hull Rules-of-Thumb''' ===

* Hulls are simple, box barges - rectangular in plan and section views.

* Hulls are constructed from whole and simple-fraction multiples of rectangular, off-the-shelf, sheet materials.

* Hull beam is one sheet.

* Hull length is scalable, generally in multiples (or combinations) of full length sheets.

* Hull curves are limited to the bottom ends (generally one quarter the LengthOfHull, curved in profile view) , reducing lofting, layout, spiling, cutting, beveling and bending to bare minimums.

* Hull curves are separated by a bottom dead-flat (planar section of bottom, generally one half the LengthOfHull).

* Hulls are self-rectifying and jig-less (consequences of these rules).

* All controlling numbers are rationalized (rounded), where possible, to maximize mnemonic retention, communication and accuracy.

=== '''TriloBoat Superstructure Rules-of-Thumb''' ===

* Superstructures are constructed from whole and simple-fraction multiples of rectangular, off-the-shelf, sheet materials.

* Side decks are not used (flush decks maximize strength, simplify construction and assist ventilation).

* All decks are planar (sloped to drain), pitched or section-of-cylinder (simple layout and construction).

* Where section-of-cylinder decks are used, upper hull or superstructure are canted inboard to provide slack for a single sheet span of desired crown.

* All controlling numbers are rationalized (rounded), where possible, to maximize mnemonic retention, communication and accuracy.''

=== '''TriloBoat Trade-Offs (Opposing Values)''' ===

* As one cuts away from the original ''prism'' (the rectangular slab formed by ''length'' x ''beam'' x ''draft''), one improves efficiency through the water (by reducing drag), but reduces interior volume and displacement.

* Narrow-for-length is faster through the water. Wide-for-length is slower, but more commodious and hauls more cargo for its length. I shoot for a length to beam ratio of 4:1, and compromise away in either direction, as needed.

* High end curves meet waves better, but reduce flat-water speed, displacement/buoyancy and interior volume.

* Every partial sheet generates lofting, cut-out and waste, but increases options. Simple fractions of sheets yielding round numbers (1, 1/2, 1/3, 1/4, 1/6, 1/8) generate less waste, and make for simple layout. Consider design for whole sheets where possible, and larger fractions where not.

* Curves take time, but add rigidity and reduce hull resistance, and in the superstructure shed water, add headroom and aesthetics. Consider using them sparingly where their benefits outweigh costs.

=== '''TriloBoat Suggested Features''' ===

* Hull Divisions - 1/4 LengthOverAll as bow curve, 1/2 LengthOverAll as dead-flat (no bottom curve in profile view), and 1/4 LengthOverAll as aft curve. This allows easy end-curves while generating fully rectilinear mid-ships (simplifying construction of the interior and enabling modular furnishings), and allows easy blocking and transport by flat-bed.

* Locate a bulkhead at the division between dead-flat and end curve to simplify bending the bottom planking. Other bulkheads may be recommended along the hull length, depending on length and use.

* Box girder furnishings in the interior do much to stiffen the hull, and particularly the bottom.

* Plywood sheet construction with dimensional lumber framing (glued and nailed) is the fastest wood construction method. Sawn chine logs (from wide planks) at bow and stern are faster than bending, and require no steaming.

* External appendages (e.g., rudder, off-centerboards, skegs) avoid complicated and hull-weakening housings, wells and trunks. Much easier to dismount, inspect, maintain, modify and repurpose.

* Junk Rig - Easy to build, maintain and operate with short-handed crews. Low stress and fail safer. Minimal standing rigging. Flat cut sails require only rudimentary lofting and design. May use GVCS bioplastic fabric.

=== '''Notes''' ===

* All 'rules' may be altered or ignored by end-users. Each deviation, however, costs in time, material and efficiency. End-users are advised to consider cost/benefit returns for each departure.

* The relation between end curves and dead-flat is determined by use. One extreme, no end curves and all dead-flat, produces a dock-like hull. The other extreme, no all curve and no dead-flat produces a constant 'rockered' bottom (easiest to move through water, but requires more time to build, generates more waste and reduces displacement and interior volume.

* The height of end curves is determined by use. High ends clear more waves, especially at the bow, and are suitable to sailing or exposed water hulls. Lower heights increase buoyancy and interior volume, and can be used in protected waters. A low or flat curve aft is consistent with planing hulls. There's a bit more to this that needs to be developed as an info module.

* Imperial System is recommended, unfortunately, unless using metric dimensioned sheets. This has to do with world standards for sheet dimensions generally being based on Imperial feet. Metric translations produce lengthy, non-mnemonic numbers which lead to miscommunication and error.

* The feet-inches-eighths system (a common standard in boat-building) helps simplify Imperial.

Ply sheets are readily available in 4 x 8, 10, 12, 16 and 20 foot lengths (easy beam choices), though 4x8ft sheets are standard and the most economical. We've found select, AC grade to be sufficient.

* This rule-set should be supplemented by additional information regarding selecting scantlings, height of end curves, draft considerations, and various construction methods and options. As watercraft, they are subject to a much wider skillset for their safe operation.

* Rig and lateral resistance information packs need to be developed, as well as integration with GVCS PowerCubes and related propulsion.

* The height of end curves is determined by use. High ends clear more waves, especially at the bow, and are suitable to sailing or exposed water hulls. Lower heights increase buoyancy and interior volume, and can be used in protected waters. A low or flat curve aft is consistent with planing hulls. There's a bit more to this that needs to be developed as an info module.

* Imperial System is recommended, unfortunately, unless using metric dimensioned sheets. This has to do with world standards for sheet dimensions generally being based on Imperial feet. Metric translations produce lengthy, non-mnemonic numbers which lead to miscommunication and error.

* The feet-inches-eighths system (a common standard in boat-building) helps simplify Imperial.

* Plywood sheets were the original inspiration, but the method is adaptable to any sheet material with maritime properties, such as steel and aluminum. Ply sheets are readily available in 4 x 8, 10, 12, 16 and 20 foot lengths (easy beam choices), though 4x8ft sheets are standard and the most economical. We've found select, AC grade to be sufficient.

* This rule-set should be supplemented by additional information regarding selecting scantlings, height of end curves, draft considerations, and various construction methods and options. As watercraft, they are subject to a much wider skillset for their safe operation.

* Rig and lateral resistance information packs need to be developed, as well as integration with GVCS PowerCubes and related propulsion.

== Product Ecology ==

=== From ===

A [[TriloBoat]] is assembled from sheet materials which include wood, wood composites, (bio)plastic composites, steel or aluminum. Each material may involve a different toolset, and can benefit from production by tools from the GVCS.

Wood based construction might thus involve the [[Dimensional Sawmill]]. Metal based construction might involve [[Open Source Welder]] and [[Metal Roller]]. Composite contruction might involve the [[Bioplastic Extruder]] and/or [[Chipper]]. The [[Plasma Cutter]] or [[Laser Cutter]] might be involved in fleet construction.

=== Uses ===

Hardware, propulsion electronics, gear, outfit and accessories vary from extremely simple/minimal to highly advanced, and may use one to several tools from the GVCS.

For example, a landing-craft layout might use the [[Heat Exchanger]] to power the [[Modern Steam Engine]] to turn the [[Universal Rotor]]. [[Hydraulic Motors]] might be used for various PTO (Power Take Off) tasks, or run a modified [[Backhoe]] as a loading crane. The [[Nickle-Iron Battery]] to power shipboard electronics. A [[LifeTrac III]] might be carried to enhance longshoring capabilities.

=== Creates ===

[[Transportation]] and/or [[Housing]].

=== Enables ===

The [[Truck]] and [[Car]] are enabled, in the sense that their range is extended to isolated road systems which are accessible by water.

== Status ==

The ''TriloBoat Design Formula'' is fully developed, many instances have been designed, and several vessels built and more or less intensively field tested.

=== TriloBoat Concept Development ===

To be completed:

* TriloBoat's adaptation to the OSE platform and standards.
* Designation and cross-linking as [[Open Source Boat]] and/or [[Boat]]?
* Exposure to Open Source Development?

=== TriloBoat User Manual ===

To be developed:

* Guidelines for Adaptation to particular purposes and needs.
* Guidelines for Scantlings for various material suites and construction methods.
* Guidelines for Construction Methods and Techniques for various material suites.
* Guidelines for Sail Rig options and design.
* Guidelines for Power Propulsion options and design.
* Guidelines for GVCS and other tool ecologies.
* Open Portfolio of Gear and Outfit options.

=== Bill of Materials and Manufacturing Instructions ===

Yet to be developed is an Open Portfolio of Plans for representative Instances, each meeting a general configuration of [Boat], but focused on a particular use (e.g., Landing Craft).

Each Plan would be developed from the above as per GVCS usual, once the rules generating them have stabilized in the OSD process. In effect, the TriloBoat rules and guidelines jumpstart the research and development required for each Plan.

Each Plan would be comprised of a ''Bill of Materials and Manufacturing Instructions'' for a scalable product, in the normal, GVCS format.

Unlike other tools in the GVCS, the Portfolio will contain several [OSBoats], and remain Open (may be added to as new products are developed (e.g., landing-craft, cargo carrier, tug, etc.).

=== Associated Tasks ===

The following, associated materials are presently available in fully adequate form external to OSE, but may eventually be brought into OS development?

* Safety Standards for materials and methods used.
* Marine Training materials for end-users.

Dave Zeiger: Add BOM and MI section

{{ToolTemplate2|ToolParent=Open Source Boat|ToolName=TriloBoat}}

[[Image:T32x8 CARGO Sample.jpg|thumb|center|600px|'''Sample TriloBoat Instance: T32x8 with typical cargo layout.''']]

== '''TriloBoat Overview''' ==

TriloBoats were designed by myself (Dave Zeiger) as a formula generated class of box barge (or scow) hulls based on construction from sheet materials.

The rules-of-thumb generate hundreds of instances in a wide array of sizes and functional layouts. Potential layouts include kayak, skiff, cargo carrier, landing craft, tug, ferry, houseboat, cruiser and multihull. They are compatible with sail and power. Appropriately designed, built and handled, are seaworthy across a wide range of conditions.

The rules-of-thumb are selected to simplify construction for dramatic savings in time, energy, material and money. This allows general construction by persons with very modest skills, with minimal resources and infrastructure.

I offer the TriloBoat concept as a candidate (subject to open source development) for [[Open Source Boat]] and [[Boat]].

My partner, Anke Wagner, and I have built three instances of TriloBoat, to date, including S/V SLACKTIDE, their home for the last three years. For further information, discussion, construction and sailing photos, please visit http://www.triloboats.com, and http://triloboats.blogspot.com.

== Detailed Description ==

The following is the ''[[TriloBoat]] Design Formula'', expressed as rules-of-thumb and guidelines. Taken together, they generate a class of box barge hulls. By converting generalities to specifics within these guidelines, produces one instance among thousands of possibilities.

Note that these rules develop design lines, only. Construction details are dependent on materials and methods used. Appropriate marine construction standards should be followed in the fabrication and assembly process.

=== '''TriloBoat Hull Rules-of-Thumb''' ===

* Hulls are simple, box barges - rectangular in plan and section views.

* Hulls are constructed from whole and simple-fraction multiples of rectangular, off-the-shelf, sheet materials.

* Hull beam is one sheet.

* Hull length is scalable, generally in multiples (or combinations) of full length sheets.

* Hull curves are limited to the bottom ends (generally one quarter the LengthOfHull, curved in profile view) , reducing lofting, layout, spiling, cutting, beveling and bending to bare minimums.

* Hull curves are separated by a bottom dead-flat (planar section of bottom, generally one half the LengthOfHull).

* Hulls are self-rectifying and jig-less (consequences of these rules).

* All controlling numbers are rationalized (rounded), where possible, to maximize mnemonic retention, communication and accuracy.

=== '''TriloBoat Superstructure Rules-of-Thumb''' ===

* Superstructures are constructed from whole and simple-fraction multiples of rectangular, off-the-shelf, sheet materials.

* Side decks are not used (flush decks maximize strength, simplify construction and assist ventilation).

* All decks are planar (sloped to drain), pitched or section-of-cylinder (simple layout and construction).

* Where section-of-cylinder decks are used, upper hull or superstructure are canted inboard to provide slack for a single sheet span of desired crown.

* All controlling numbers are rationalized (rounded), where possible, to maximize mnemonic retention, communication and accuracy.''

=== '''TriloBoat Trade-Offs (Opposing Values)''' ===

* As one cuts away from the original ''prism'' (the rectangular slab formed by ''length'' x ''beam'' x ''draft''), one improves efficiency through the water (by reducing drag), but reduces interior volume and displacement.

* Narrow-for-length is faster through the water. Wide-for-length is slower, but more commodious and hauls more cargo for its length. I shoot for a length to beam ratio of 4:1, and compromise away in either direction, as needed.

* High end curves meet waves better, but reduce flat-water speed, displacement/buoyancy and interior volume.

* Every partial sheet generates lofting, cut-out and waste, but increases options. Simple fractions of sheets yielding round numbers (1, 1/2, 1/3, 1/4, 1/6, 1/8) generate less waste, and make for simple layout. Consider design for whole sheets where possible, and larger fractions where not.

* Curves take time, but add rigidity and reduce hull resistance, and in the superstructure shed water, add headroom and aesthetics. Consider using them sparingly where their benefits outweigh costs.

=== '''TriloBoat Suggested Features''' ===

* Hull Divisions - 1/4 LengthOverAll as bow curve, 1/2 LengthOverAll as dead-flat (no bottom curve in profile view), and 1/4 LengthOverAll as aft curve. This allows easy end-curves while generating fully rectilinear mid-ships (simplifying construction of the interior and enabling modular furnishings), and allows easy blocking and transport by flat-bed.

* Locate a bulkhead at the division between dead-flat and end curve to simplify bending the bottom planking. Other bulkheads may be recommended along the hull length, depending on length and use.

* Box girder furnishings in the interior do much to stiffen the hull, and particularly the bottom.

* Plywood sheet construction with dimensional lumber framing (glued and nailed) is the fastest wood construction method. Sawn chine logs (from wide planks) at bow and stern are faster than bending, and require no steaming.

* External appendages (e.g., rudder, off-centerboards, skegs). This avoids complicated and weakening housings, wells and trunks. Much easier to dismount, inspect, maintain, modify and repurpose.

* Junk Rig - Easy to build, maintain and operate with short-handed crews. Low stress and fail safer. Minimal standing rigging. Flat cut sails require only rudimentary lofting and design. May use GVCS bioplastic fabric.

=== '''Notes''' ===

* All 'rules' may be altered or ignored by end-users. Each deviation, however, costs in time, material and efficiency. End-users are advised to consider cost/benefit returns for each departure.

* The relation between end curves and dead-flat is determined by use. One extreme, no end curves and all dead-flat, produces a dock-like hull. The other extreme, no all curve and no dead-flat produces a constant 'rockered' bottom (easiest to move through water, but requires more time to build, generates more waste and reduces displacement and interior volume.

* The height of end curves is determined by use. High ends clear more waves, especially at the bow, and are suitable to sailing or exposed water hulls.

Dave Zeiger: reorder topic sequence

== Introducing Myself ([[Dave Zeiger]]) ==

Hi Folks,

I'm the originator of the TriloBoat concept, which I've offered up for OSDevelopment.

I took the wiki instructions to heart and did a 'braindump' on the content page. I realize that it needs to be deeply edited to bring it into conformity with OSE and general wiki format. Please excuse my gaffes.

Due to time and access restrictions (we're about to sail off the edge, again), I won't be able to participate often or at length. I will, however, check in as often as I can.

If you have any particular questions I can help with, please visit my site at http://www.triloboats.com or blog at http://triloboats.blogspot.com, where I have a lot of information posted, or write me at ''triloboats AT gmail DOT com''. I'll be sailing, and slow getting back to you, but unless overwhelmed by volume, will eventually write back.

[[Dave Zeiger]]

== Enabling the TriloBoat Approach vs Product ==

I note that TriloBoat (any ''Boat'', for that matter) will be an unusual project within the OSE, with many more variables than is usual in product development. This won't be a case of zeroing in on a design for a single, modular tool.

''(OR, if it IS decided to BE a single product approach, the rule set can be further constrained... focus on hull only, make ends uniform (limited to a single sheet), and only scale by beam and adding sheets to lengthen or shorten... this, however, severely limits adaptability, and is a relatively trivial result... this might, however, be the core product design within a larger design portfolio.)''

The Bill of Materials and Builder's Instructions, for example, are going to be very different if using steel vs plywood vs composite construction, as will portions of the User's Manual. A landing craft will have wildly different requirements than a sailing coaster or skiff. Being more approach than product, it's going to take some special handling.

I'd suggest that the OSD process re TriloBoat orient itself from the outset toward enabling end-users to follow a number of paths through the TriloBoat 'design space' as well as the subsequent build.

Design guidelines, various material suites with associated construction techniques and methods, layout and outfit options - the ''erector set'' approach - will be much more versatile than any given plan or set of plans.

That being said, a portfolio of product-level designs for various configurations will be useful, and sufficient for most end-users - each design similar to the standard OSE product, and all under the header of [[Boat]]

[[Dave Zeiger]]

== TriloBoat Design Decision Tree? ==

[[Boat]] concept strikes me as a bit unusual within the GVCS, in that it is scalable and adaptable to a far wider degree than, say, the [[Truck]] or [[Car]].

Decisions that will go into a [[Boat]] include materials, method, size, intended conditions (eg, protected vs open waters), intended purpose, and propulsion methods. It will be outfitted with a far wider range of tools, and can be 'packaged' with other tools to a far greater degree.

TriloBoat narrows the range considerably by rules-of-thumb constraining shape, but still generates a class of thousands of instances. By the time even GVCS options are factored in, the class is... um... freaking ''huge!''

I propose that a Design Decision Tree be given OS consideration, as a means of navigating the ''class'' of TriloBoats, to assist arrival at an ''instance'' of TriloBoat.

Questions include:

* Do we want to spend time/energy on this?
* How to prioritize the tree?
* How to represent the tree?
* Can navigating the tree be computer assisted?
* How best to integrate the tree with other materials?
* Can this approach be generalized to work with other OS development?

 BA in Philosophy from Lewis & Clark College, Portland, OR.
 
 Software Programmer/Consultant, 1980-1990.
 
 Sailor, 1990 to present.
 Boat Builder, 1995 to present.
 Boat Design, 1996 to present. Developed TRILOBOAT (barge) Formula, 2003.
 (www.triloboats.com... under submission to the GVCS).
 
 These sites have more about my work and our life:
 
 http://www.triloboats.com
 http://www.triloboats.blogspot.com

==='''WHY''' are you motivated to support/develop this work?===
*''Do you endorse open source culture?''
Yes.
 
 I believe OS culture promotes and embodies the 'commonwealth' far more than has historically been the case. I see it as a viable and necessary alternative to private property with its associated supply-and-demand market thinking.
 
 Participatory, egalitarian, transparent, consentual, DIY, anarchic... all concepts near and dear to my heart!

*''Why are you interested in collaborating with us?''
I believe the Triloboat (scalable and modular box barge) Formula fits your approach and the CVCS well. Barges are versatile tools for transportation, cargo carrying, subsistence fishing and housing.
 
 My own idea for them is to be widely seeded, enabling many to get afloat who might not otherwise be able to afford or manage it. I see the GVCS as a 'viral' idea, in its own right. I think the two would make good traveling companions.

*''How do you think that the GVCS can address pressing world issues?''
It's strength, I believe, lies in the participatory, DIY approach. It is extremely empowering and socializing (vs. depowering and alienating in standard industrial paradigms).
 
 By localizing industry, supply chains are shortened and simplified, capital resources largely remain within the community, and the toolset is adaptable to local needs (vs. standard one-size-fits-all). This empowers communities naturally toward subsistence modes, which I see as the only conceivable basis for sustainable economies.

*''What should happen so that you become more involved with the project?''
If you accept the Triloboats concept as a member of the GVCS, or some related role, then I will become more involved.

*''What is missing in the project?''
I note that you lack water/sail transport... a BOAT tool.

BOAT is one of THE basic tools. On a planet that is 75% water, and whose landmasses are laced with navigable waters, BOAT represents distributed transport with little to no required infrastructure.

As Tristan Jones points out, "A sailboat is the only vehicle on the plantet with unlimited range." They are fuel efficient, accessible, have a healthy DIY tradition, and often the center of vital social cultures.

The synergies between BOAT and the other tools in the GVCS is high. Unlike TRUCK, BOAT may scaled to the point where it can transport the entire GVCS (as well as materials and personnel), in a single passage, to isolated or roadless areas accessible by water.

*''What are your suggestions for improvement of the project?''
At present, I'm on an approach pattern. Will get back to you as I gain more familiarity with the project.

A first impression, however relates to naming conventions (tool parenting). I would suggest standardizing all tools in the format TOOL NAME > OPEN SOURCE TOOL NAME > TOOL NICKNAME, with standardized information pertaining at each level. Looking around the OSE Wiki, I've found pages with development at all three levels, but no strong consistency.

==='''WHAT''' are your skills?===

*'''List all of your skills in these areas: Communications - Organizational - Computer Support - Finances - Design - Natural Building - Electronics - Automation - Metallurgy - Engineering - Fabrication - Agriculture - Energy - Architecture - Video/Graphics/Art - PR/Marketing - Education - Construction - Industry - CNC - Chemistry - Product Design - Other'''
My major contribution, if accepted, will be in Design/Product Design.
 
 I bring a simple, highly developed formula for box barge design, for construction in sheet materials (http://www.triloboats.com). The formula generates a large class of instances (modular, as individuals or fleets) of varying sizes (scalable).
 
 These hulls (and the principles that generate them) are consistent with and productive of a wide array of super-structures and layouts, supporting a huge range of needs.
 
 It may serve as a starting point for OS development, but likely only at the instance level. The central rules-of-thumb have been likely simplified as much as possible. Development from this point will likely be in application specific plan categories (cargo, landing craft, passenger transport, live-aboard, etc.), and a comprehensive User Manual.
 
 My particular interest and expertise is in sail power, though GVCS power sources are perfectly applicable to these barges.
 
 I see my role as assisting in the initial product wiki, then consulting and advising where possible.

Additionally, I have skills in carpentry, computer systems, CAD and technical writing.

*''How have you already contributed to the project?''
To date, only to the extent that I have offered my design formula, gratis, to the project, and started development of the page http://opensourceecology.org/wiki/Triloboat.

===HOW can you help?===

*''How are you interested in contributing to the work of GVCS development?''
Primarily through the donation of a core tool (BOAT). Secondarily, through providing input to OS development of the concept.

*''Can you volunteer to work with us, and if so, how many hours per week?''
I would like to volunteer time and energy. My ability to connect with internet (or other communication channels) is very sporadic, so it would be on an occasional, drop-in basis.

*''Are you interested in working with us for pay? If so, what services can you offer, and what is your hourly or per-project rate?''
It's possible, on a contract, case-by-case basis.
 
 Services are in consulting, review of and feedback to OS development process and waypoints re the Triloboat Formula and related gear and outfit.
 
 Pay would depend on circumstances, but I will generally work for well below market pay rates.

*''Are you interested in a [[Dedicated Project Visit]]?
Not at this point, though I may be in the future.

*''Are you interested in purchasing equipment from us to help bootstrap development?''
No, thank you.

*''Are you interested in bidding for consulting/design/prototyping work?''
Possibly, in the future.

*''Are you a [[True Fans|True Fan]]? If not, why not?''
No.

Our financial structure (so-called) is such that we contribute to causes on a once-a-year basis, in the form of lump donations (no subscription-type pledges). We will, however, add the GVCS to our list of candidates!

*''Would you like to see yourself working with us on a full-time basis?''
No, thank you. On-going, yes; full-time, no.

*''Are you interested in being part of the world's first, open source, resilient community? The GVCS is the preparatory step for the OSE Village Experiment â€“ a 2 year, immersion experiment (2013-2014) for testing whether a real, thriving, modern-day prototype community of 200 people can be built on 200 acres using local resources and open access to information? We are looking for approximately 200 people to fill a diverse array of roles, according to the Social Contract that is being developed. This may be the boldest social experiment on earth - a pioneering community whose goal is to extend the index of possibilities regarding harmonious existence of humans, ecology, and technology.''
No, thank you, though I will be following with great interest.

*''Introductory Video'' - http://www.youtube.com/watch?v=ZlGZW4NVaP8
*''Resume/CV'' - http://www.triloboats.com/aboutus.html
 
 BA in Philosophy from Lewis & Clark College, Portland, OR.
 
 Software Programmer/Consultant, 1980-1990.
 
 Sailor, 1990 to present.
 Boat Builder, 1995 to present.
 Boat Design, 1996 to present. Developed TRILOBOAT (barge) Formula, 2003.
 (www.triloboats.com... under submission to the GVCS).

==='''WHY''' are you motivated to support/develop this work?===
*''Do you endorse open source culture?''
Yes.
 
 I believe OS culture promotes and embodies the 'commonwealth' far more than has historically been the case. I see it as a viable and necessary alternative to private property with its associated supply-and-demand market thinking.
 
 Participatory, egalitarian, transparent, consentual, DIY, anarchic... all concepts near and dear to my heart!

*''Why are you interested in collaborating with us?''
I believe the Triloboat (scalable and modular box barge) Formula fits your approach and the CVCS well. Barges are versatile tools for transportation, cargo carrying, subsistence fishing and housing.
 
 My own idea for them is to be widely seeded, enabling many to get afloat who might not otherwise be able to afford or manage it. I see the GVCS as a 'viral' idea, in its own right. I think the two would make good traveling companions.

*''How do you think that the GVCS can address pressing world issues?''
It's strength, I believe, lies in the participatory, DIY approach. It is extremely empowering and socializing (vs. depowering and alienating in standard industrial paradigms).
 
 By localizing industry, supply chains are shortened and simplified, capital resources largely remain within the community, and the toolset is adaptable to local needs (vs. standard one-size-fits-all). This empowers communities naturally toward subsistence modes, which I see as the only conceivable basis for sustainable economies.

*''What should happen so that you become more involved with the project?''
If you accept the Triloboats concept as a member of the GVCS, or some related role, then I will become more involved.

*''What is missing in the project?''
I note that you lack water/sail transport... a BOAT tool.

BOAT is one of THE basic tools. On a planet that is 75% water, and whose landmasses are laced with navigable waters, BOAT represents distributed transport with little to no required infrastructure.

As Tristan Jones points out, "A sailboat is the only vehicle on the plantet with unlimited range." They are fuel efficient, accessible, have a healthy DIY tradition, and often the center of vital social cultures.

The synergies between BOAT and the other tools in the GVCS is high. Unlike TRUCK, BOAT may scaled to the point where it can transport the entire GVCS (as well as materials and personnel), in a single passage, to isolated or roadless areas accessible by water.

*''What are your suggestions for improvement of the project?''
At present, I'm on an approach pattern. Will get back to you as I gain more familiarity with the project.

A first impression, however relates to naming conventions (tool parenting). I would suggest standardizing all tools in the format TOOL NAME > OPEN SOURCE TOOL NAME > TOOL NICKNAME, with standardized information pertaining at each level. Looking around the OSE Wiki, I've found pages with development at all three levels, but no strong consistency.

==='''WHAT''' are your skills?===

*'''List all of your skills in these areas: Communications - Organizational - Computer Support - Finances - Design - Natural Building - Electronics - Automation - Metallurgy - Engineering - Fabrication - Agriculture - Energy - Architecture - Video/Graphics/Art - PR/Marketing - Education - Construction - Industry - CNC - Chemistry - Product Design - Other'''
My major contribution, if accepted, will be in Design/Product Design.
 
 I bring a simple, highly developed formula for box barge design, for construction in sheet materials (www.triloboats.com). The formula generates a large class of instances (modular, as individuals or fleets) of varying sizes (scalable).
 
 These hulls (and the principles that generate them) are consistent with and productive of a wide array of super-structures and layouts, supporting a huge range of needs.
 
 It may serve as a starting point for OS development, but likely only at the instance level. The central rules-of-thumb have been likely simplified as much as possible. Development from this point will likely be in application specific plan categories (cargo, landing craft, passenger transport, live-aboard, etc.).
 
 My particular interest and expertise is in sail power, though GVCS power sources are perfectly applicable to these barges.
 
 I see my role as assisting in the initial product wiki, then consulting and advising where possible.

*''How have you already contributed to the project?''
To date, only to the extent that I have offered my design formula, gratis, to the project.

===HOW can you help?===

*''How are you interested in contributing to the work of GVCS development?''
Primarily through the donation of a core tool description (class of box barges). Secondarily, through providing input to OS development of the concept.

*''Can you volunteer to work with us, and if so, how many hours per week?''
I would like to volunteer time and energy. My ability to connect with internet (or other communication channels) is very sporadic, so it would be on an occasional, drop-in basis.

*''Are you interested in working with us for pay? If so, what services can you offer, and what is your hourly or per-project rate?''
It's possible, on a contract, case-by-case basis.
 
 Services are in consulting, review of and feedback to OS development process and waypoints re the Triloboat Formula and related gear and outfit.
 
 Pay would depend on circumstances, but I will generally work for well below market pay rates.

*''Are you interested in a [[Dedicated Project Visit]]?
Not at this point, though I may be in the future.

*''Are you interested in purchasing equipment from us to help bootstrap development?''
No, thank you.

*''Are you interested in bidding for consulting/design/prototyping work?''
Possibly, in the future.

*''Are you a [[True Fans|True Fan]]? If not, why not?''
Yes and No. Yes for all the obvious reasons. No, as I believe that the window in which this project can be successful for the long term has been closed, by late response to Peak Oil, et al.

*''Would you like to see yourself working with us on a full-time basis?''
No, thank you. On-going, yes; full-time, no.

*''Are you interested in being part of the world's first, open source, resilient community? The GVCS is the preparatory step for the OSE Village Experiment â€“ a 2 year, immersion experiment (2013-2014) for testing whether a real, thriving, modern-day prototype community of 200 people can be built on 200 acres using local resources and open access to information? We are looking for approximately 200 people to fill a diverse array of roles, according to the Social Contract that is being developed. This may be the boldest social experiment on earth - a pioneering community whose goal is to extend the index of possibilities regarding harmonious existence of humans, ecology, and technology.''
No, thank you, though I will be following with great interest.

Dave Zeiger: /* TriloBoat User Manual */ Add Sail and Power guidelines

{{ToolTemplate2|ToolParent=Open Source Boat|ToolName=TriloBoat}}

[[Image:T32x8 CARGO Sample.jpg|thumb|center|600px|'''Sample TriloBoat Instance: T32x8 with typical cargo layout.''']]

== '''TriloBoat Overview''' ==

TriloBoats were designed by myself (Dave Zeiger) as a formula generated class of box barge (or scow) hulls based on construction from sheet materials.

The rules-of-thumb generate hundreds of instances in a wide array of sizes and functional layouts. Potential layouts include kayak, skiff, cargo carrier, landing craft, tug, ferry, houseboat, cruiser and multihull. They are compatible with sail and power. Appropriately designed, built and handled, are seaworthy across a wide range of conditions.

The rules-of-thumb are selected to simplify construction for dramatic savings in time, energy, material and money. This allows general construction by persons with very modest skills, with minimal resources and infrastructure.

I offer the TriloBoat concept as a candidate (subject to open source development) for [[Open Source Boat]] and [[Boat]].

My partner, Anke Wagner, and I have built three instances of TriloBoat, to date, including S/V SLACKTIDE, their home for the last three years. For further information, discussion, construction and sailing photos, please visit http://www.triloboats.com, and http://triloboats.blogspot.com.

== Detailed Description ==

The following is the ''[[TriloBoat]] Design Formula'', expressed as rules-of-thumb and guidelines. Taken together, they generate a class of box barge hulls. By converting generalities to specifics within these guidelines, produces one instance among thousands of possibilities.

Note that these rules develop design lines, only. Construction details are dependent on materials and methods used. Appropriate marine construction standards should be followed in the fabrication and assembly process.

=== '''TriloBoat Hull Rules-of-Thumb''' ===

* Hulls are simple, box barges - rectangular in plan and section views.

* Hulls are constructed from whole and simple-fraction multiples of rectangular, off-the-shelf, sheet materials.

* Hull beam is one sheet.

* Hull length is scalable, generally in multiples (or combinations) of full length sheets.

* Hull curves are limited to the bottom ends (generally one quarter the LengthOfHull, curved in profile view) , reducing lofting, layout, spiling, cutting, beveling and bending to bare minimums.

* Hull curves are separated by a bottom dead-flat (planar section of bottom, generally one half the LengthOfHull).

* Hulls are self-rectifying and jig-less (consequences of these rules).

* All controlling numbers are rationalized (rounded), where possible, to maximize mnemonic retention, communication and accuracy.

=== '''TriloBoat Superstructure Rules-of-Thumb''' ===

* Superstructures are constructed from whole and simple-fraction multiples of rectangular, off-the-shelf, sheet materials.

* Side decks are not used (flush decks maximize strength, simplify construction and assist ventilation).

* All decks are planar (sloped to drain), pitched or section-of-cylinder (simple layout and construction).

* Where section-of-cylinder decks are used, upper hull or superstructure are canted inboard to provide slack for a single sheet span of desired crown.

* All controlling numbers are rationalized (rounded), where possible, to maximize mnemonic retention, communication and accuracy.''

=== '''TriloBoat Trade-Offs (Opposing Values)''' ===

* As one cuts away from the original ''prism'' (the rectangular slab formed by ''length'' x ''beam'' x ''draft''), one improves efficiency through the water (by reducing drag), but reduces interior volume and displacement.

* Narrow-for-length is faster through the water. Wide-for-length is slower, but more commodious and hauls more cargo for its length. I shoot for a length to beam ratio of 4:1, and compromise away in either direction, as needed.

* High end curves meet waves better, but reduce flat-water speed, displacement/buoyancy and interior volume.

* Every partial sheet generates lofting, cut-out and waste, but increases options. Simple fractions of sheets yielding round numbers (1, 1/2, 1/3, 1/4, 1/6, 1/8) generate less waste, and make for simple layout. Consider design for whole sheets where possible, and larger fractions where not.

* Curves take time, but add rigidity and reduce hull resistance, and in the superstructure shed water, add headroom and aesthetics. Consider using them sparingly where their benefits outweigh costs.

=== '''TriloBoat Suggested Features''' ===

* Hull Divisions - 1/4 LengthOverAll as bow curve, 1/2 LengthOverAll as dead-flat (no bottom curve in profile view), and 1/4 LengthOverAll as aft curve. This allows easy end-curves while generating fully rectilinear mid-ships (simplifying construction of the interior and enabling modular furnishings), and allows easy blocking and transport by flat-bed.

* Locate a bulkhead at the division between dead-flat and end curve to simplify bending the bottom planking. Other bulkheads may be recommended along the hull length, depending on length and use.

* Box girder furnishings in the interior do much to stiffen the hull, and particularly the bottom.

* Plywood sheet construction with dimensional lumber framing (glued and nailed) is the fastest wood construction method. Sawn chine logs (from wide planks) at bow and stern are faster than bending, and require no steaming.

* External appendages (e.g., rudder, off-centerboards, skegs). This avoids complicated and weakening housings, wells and trunks. Much easier to dismount, inspect, maintain, modify and repurpose.

* Junk Rig - Easy to build, maintain and operate with short-handed crews. Low stress and fail safer. Minimal standing rigging. Flat cut sails require only rudimentary lofting and design. May use GVCS bioplastic fabric.

=== '''Notes''' ===

* All 'rules' may be altered or ignored by end-users. Each deviation, however, costs in time, material and efficiency. End-users are advised to consider cost/benefit returns for each departure.

* The relation between end curves and dead-flat is determined by use. One extreme, no end curves and all dead-flat, produces a dock-like hull. The other extreme, no all curve and no dead-flat produces a constant 'rockered' bottom (easiest to move through water, but requires more time to build, generates more waste and reduces displacement and interior volume.

* The height of end curves is determined by use. High ends clear more waves, especially at the bow, and are suitable to sailing or exposed water hulls. Lower heights increase buoyancy and interior volume, and can be used in protected waters. A low or flat curve aft is consistent with planing hulls. There's a bit more to this that needs to be developed as an info module.

* Imperial System is recommended, unfortunately, unless using metric dimensioned sheets. This has to do with world standards for sheet dimensions generally being based on Imperial feet. Metric translations produce lengthy, non-mnemonic numbers which lead to miscommunication and error.

* The feet-inches-eighths system (a common standard in boat-building) helps simplify Imperial.

* Plywood sheets were the original inspiration, but the method is adaptable to any sheet material with maritime properties, such as steel and aluminum. Ply sheets are readily available in 4 x 8, 10, 12, 16 and 20 foot lengths (easy beam choices), though 4x8ft sheets are standard and the most economical. We've found select, AC grade to be sufficient.

* This rule-set should be supplemented by additional information regarding selecting scantlings, height of end curves, draft considerations, and various construction methods and options. As watercraft, they are subject to a much wider skillset for their safe operation.

* Rig and lateral resistance information packs need to be developed, as well as integration with GVCS PowerCubes and related propulsion.

== Product Ecology ==

=== From ===

A [[TriloBoat]] is assembled from sheet materials which include wood, wood composites, (bio)plastic composites, steel or aluminum. Each material may involve a different toolset, and can benefit from production by tools from the GVCS.

Wood based construction might thus involve the [[Dimensional Sawmill]]. Metal based construction might involve [[Open Source Welder]] and [[Metal Roller]]. Composite contruction might involve the [[Bioplastic Extruder]] and/or [[Chipper]]. The [[Plasma Cutter]] or [[Laser Cutter]] might be involved in fleet construction.

=== Uses ===

Hardware, propulsion electronics, gear, outfit and accessories vary from extremely simple/minimal to highly advanced, and may use one to several tools from the GVCS.

For example, a landing-craft layout might use the [[Heat Exchanger]] to power the [[Modern Steam Engine]] to turn the [[Universal Rotor]]. [[Hydraulic Motors]] might be used for various PTO (Power Take Off) tasks, or run a modified [[Backhoe]] as a loading crane. The [[Nickle-Iron Battery]] to power shipboard electronics. A [[LifeTrac III]] might be carried to enhance longshoring capabilities.

=== Creates ===

[[Transportation]] and/or [[Housing]].

=== Enables ===

The [[Truck]] and [[Car]] are enabled, in the sense that their range is extended to isolated road systems which are accessible by water.

== Status ==

The ''TriloBoat Design Formula'' is fully developed, many instances have been designed, and several vessels built and more or less intensively field tested.

=== TriloBoat Concept Development ===

To be completed:

* TriloBoat's adaptation to the OSE platform and standards.
* Designation and cross-linking as [[Open Source Boat]] and/or [[Boat]]?
* Exposure to Open Source Development?

=== TriloBoat User Manual ===

To be developed:

* Guidelines for Adaptation to particular purposes and needs.
* Guidelines for Scantlings for various material suites and construction methods.
* Guidelines for Construction Methods and Techniques for various material suites.
* Guidelines for Sail Rig options and design.
* Guidelines for Power Propulsion options and design.
* Open Portfolio of Gear and Outfit options.
* Open Portfolio of Plans for representative instances.

=== Associated Tasks ===

The following, associated materials are presently available in fully adequate form external to OSE, but may eventually be brought into OS development?

* Safety Standards for materials and methods used.
* Marine Training materials for end-users.

== Product Ecology ==

=== From ===

A [[TriloBoat]] is assembled from sheet materials which include wood, wood composites, (bio)plastic composites, steel or aluminum. Each material may involve a different toolset, and can benefit from production by tools from the GVCS.

Wood based construction might thus involve the [[Dimensional Sawmill]]. Metal based construction might involve [[Open Source Welder]] and [[Metal Roller]]. Composite contruction might involve the [[Bioplastic Extruder]] and/or [[Chipper]]. The [[Plasma Cutter]] or [[Laser Cutter]] might be involved in fleet construction.

=== Uses ===

Hardware, propulsion electronics, gear, outfit and accessories vary from extremely simple/minimal to highly advanced, and may use one to several tools from the GVCS.

For example, a landing-craft layout might use the [[Heat Exchanger]] to power the [[Modern Steam Engine]] to turn the [[Universal Rotor]]. [[Hydraulic Motors]] might be used for various PTO (Power Take Off) tasks, or run a modified [[Backhoe]] as a loading crane. The [[Nickle-Iron Battery]] to power shipboard electronics.

[[Image:T32x8 CARGO Sample.jpg|thumb|center|600px|'''Sample TriloBoat Instance: T32x8 with typical cargo layout.''']]

== '''TriloBoat Overview''' ==

TriloBoats were designed by Dave Zeiger as a formula generated class of box barge (or scow) hulls based on construction from sheet materials.

The rules-of-thumb generate hundreds of instances in a wide array of sizes and functional layouts. Potential layouts include kayak, skiff, cargo carrier, tug, ferry, houseboat, cruiser and multihull. They are compatible with sail and power.

The rules-of-thumb are selected to simplify construction for dramatic savings in time, energy, material and money.

Triloboats are being offered as a starting point for the Open Source Boat (OSBoat)[http://opensourceecology.org/wiki/Open_Source_Boat].

With his partner, Anke Wagner, Dave has built three instances of TriloBoat, to date, including S/V SLACKTIDE, their home for the last three years. For further information, discussion, construction and sailing photos, please visit http://www.triloboats.com, and http://triloboats.blogspot.com.

== Detailed Description ==

The following is the ''[[TriloBoat]] Design Formula'', expressed as rules-of-thumb and guidelines. Taken together, they generate a class of box barge hulls. By converting generalities to specifics within these guidelines, produces one instance among thousands of possibilities.

Note that these rules develop design lines, only. Construction details are dependent on materials and methods used. Appropriate marine construction standards should be followed in the fabrication and assembly process.

=== '''TriloBoat Hull Rules-of-Thumb''' ===

* Hulls are simple, box barges - rectangular in plan and section views.

* Hulls are constructed from whole and simple-fraction multiples of rectangular, off-the-shelf, sheet materials.

* Hull beam is one sheet.

* Hull length is scalable, generally in multiples (or combinations) of full length sheets.

* Hull curves are limited to the bottom ends (generally one quarter the LengthOfHull, curved in profile view) , reducing lofting, layout, spiling, cutting, beveling and bending to bare minimums.

* Hull curves are separated by a bottom dead-flat (planar section of bottom, generally one half the LengthOfHull).

* Hulls are self-rectifying and jig-less (consequences of these rules).

* All controlling numbers are rationalized (rounded), where possible, to maximize mnemonic retention, communication and accuracy.

=== '''TriloBoat Superstructure Rules-of-Thumb''' ===

* Superstructures are constructed from whole and simple-fraction multiples of rectangular, off-the-shelf, sheet materials.

* Side decks are not used (flush decks maximize strength, simplify construction and assist ventilation).

* All decks are planar (sloped to drain), pitched or section-of-cylinder (simple layout and construction).

* Where section-of-cylinder decks are used, upper hull or superstructure are canted inboard to provide slack for a single sheet span of desired crown.

* All controlling numbers are rationalized (rounded), where possible, to maximize mnemonic retention, communication and accuracy.''

=== '''TriloBoat Trade-Offs (Opposing Values)''' ===

* As one cuts away from the original ''prism'' (the rectangular slab formed by ''length'' x ''beam'' x ''draft''), one improves efficiency through the water (by reducing drag), but reduces interior volume and displacement.

* Narrow-for-length is faster through the water. Wide-for-length is slower, but more commodious and hauls more cargo for its length. I shoot for a length to beam ratio of 4:1, and compromise away in either direction, as needed.

* High end curves meet waves better, but reduce flat-water speed, displacement/buoyancy and interior volume.

* Every partial sheet generates lofting, cut-out and waste, but increases options. Simple fractions of sheets yielding round numbers (1, 1/2, 1/3, 1/4, 1/6, 1/8) generate less waste, and make for simple layout. Consider design for whole sheets where possible, and larger fractions where not.

* Curves take time, but add rigidity and reduce hull resistance, and in the superstructure shed water, add headroom and aesthetics. Consider using them sparingly where their benefits outweigh costs.

=== '''TriloBoat Suggested Features''' ===

* Hull Divisions - 1/4 LengthOverAll as bow curve, 1/2 LengthOverAll as dead-flat (no bottom curve in profile view), and 1/4 LengthOverAll as aft curve. This allows easy end-curves while generating fully rectilinear mid-ships (simplifying construction of the interior and enabling modular furnishings), and allows easy blocking and transport by flat-bed.

* Locate a bulkhead at the division between dead-flat and end curve to simplify bending the bottom planking. Other bulkheads may be recommended along the hull length, depending on length and use.

* Box girder furnishings in the interior do much to stiffen the hull, and particularly the bottom.

* Plywood sheet construction with dimensional lumber framing (glued and nailed) is the fastest wood construction method. Sawn chine logs (from wide planks) at bow and stern are faster than bending, and require no steaming.

* External appendages (e.g., rudder, off-centerboards, skegs). This avoids complicated and weakening housings, wells and trunks. Much easier to dismount, inspect, maintain, modify and repurpose.

* Junk Rig - Easy to build, maintain and operate with short-handed crews. Low stress and fail safer. Minimal standing rigging. Flat cut sails require only rudimentary lofting and design. May use GVCS bioplastic fabric.

=== '''Notes''' ===

* All 'rules' may be altered or ignored by end-users. Each deviation, however, costs in time, material and efficiency. End-users are advised to consider cost/benefit returns for each departure.

== '''TriloBoat Overview''' ==

TriloBoats were designed by Dave Zeiger as a formula generated class of box barge (or scow) hulls based on construction from sheet materials.

The rules-of-thumb generate hundreds of instances in a wide array of sizes and functional layouts. Potential layouts include kayak, skiff, cargo carrier, tug, ferry, houseboat, cruiser and multihull. They are compatible with sail and power.

The rules-of-thumb are selected to simplify construction for dramatic savings in time, energy, material and money.

Triloboats are being offered as a starting point for the Open Source Boat (OSBoat)[http://opensourceecology.org/wiki/Open_Source_Boat].

With his partner, Anke Wagner, Dave has built three instances of TriloBoat, to date, including S/V SLACKTIDE, their home for the last three years. For further information, discussion, construction and sailing photos, please visit http://www.triloboats.com, and http://triloboats.blogspot.com.

== Detailed Description ==

The following is the ''[[TriloBoat]] Design Formula'', expressed as rules-of-thumb and guidelines. Taken together, they generate a class of box barge hulls. By converting generalities to specifics within these guidelines, produces one instance among thousands of possibilities.

Note that these rules develop design lines, only. Construction details are dependent on materials and methods used. Appropriate marine construction standards should be followed in the fabrication and assembly process.

=== '''TriloBoat Hull Rules-of-Thumb''' ===

* Hulls are simple, box barges - rectangular in plan and section views.

* Hulls are constructed from whole and simple-fraction multiples of rectangular, off-the-shelf, sheet materials.

* Hull beam is one sheet.

* Hull length is scalable, generally in multiples (or combinations) of full length sheets.

* Hull curves are limited to the bottom ends (generally one quarter the LengthOfHull, curved in profile view) , reducing lofting, layout, spiling, cutting, beveling and bending to bare minimums.

* Hull curves are separated by a bottom dead-flat (planar section of bottom, generally one half the LengthOfHull).

* Hulls are self-rectifying and jig-less (consequences of these rules).

* All controlling numbers are rationalized (rounded), where possible, to maximize mnemonic retention, communication and accuracy.

=== '''TriloBoat Superstructure Rules-of-Thumb''' ===

* Superstructures are constructed from whole and simple-fraction multiples of rectangular, off-the-shelf, sheet materials.

* Side decks are not used (flush decks maximize strength, simplify construction and assist ventilation).

* All decks are planar (sloped to drain), pitched or section-of-cylinder (simple layout and construction).

* Where section-of-cylinder decks are used, upper hull or superstructure are canted inboard to provide slack for a single sheet span of desired crown.

* All controlling numbers are rationalized (rounded), where possible, to maximize mnemonic retention, communication and accuracy.''

=== '''TriloBoat Trade-Offs (Opposing Values)''' ===

* As one cuts away from the original ''prism'' (the rectangular slab formed by ''length'' x ''beam'' x ''draft''), one improves efficiency through the water (by reducing drag), but reduces interior volume and displacement.

* Narrow-for-length is faster through the water. Wide-for-length is slower, but more commodious and hauls more cargo for its length. I shoot for a length to beam ratio of 4:1, and compromise away in either direction, as needed.

* High end curves meet waves better, but reduce flat-water speed, displacement/buoyancy and interior volume.

* Every partial sheet generates lofting, cut-out and waste, but increases options. Simple fractions of sheets yielding round numbers (1, 1/2, 1/3, 1/4, 1/6, 1/8) generate less waste, and make for simple layout. Consider design for whole sheets where possible, and larger fractions where not.

* Curves take time, but add rigidity and reduce hull resistance, and in the superstructure shed water, add headroom and aesthetics. Consider using them sparingly where their benefits outweigh costs.

=== '''TriloBoat Suggested Features''' ===

* Hull Divisions - 1/4 LengthOverAll as bow curve, 1/2 LengthOverAll as dead-flat (no bottom curve in profile view), and 1/4 LengthOverAll as aft curve. This allows easy end-curves while generating fully rectilinear mid-ships (simplifying construction of the interior and enabling modular furnishings), and allows easy blocking and transport by flat-bed.

* Locate a bulkhead at the division between dead-flat and end curve to simplify bending the bottom planking. Other bulkheads may be recommended along the hull length, depending on length and use.

* Box girder furnishings in the interior do much to stiffen the hull, and particularly the bottom.

* Plywood sheet construction with dimensional lumber framing (glued and nailed) is the fastest wood construction method. Sawn chine logs (from wide planks) at bow and stern are faster than bending, and require no steaming.

* External appendages (e.g., rudder, off-centerboards, skegs). This avoids complicated and weakening housings, wells and trunks. Much easier to dismount, inspect, maintain, modify and repurpose.

* Junk Rig - Easy to build, maintain and operate with short-handed crews. Low stress and fail safer. Minimal standing rigging. Flat cut sails require only rudimentary lofting and design. May use GVCS bioplastic fabric.

=== '''Notes''' ===

* All 'rules' may be altered or ignored by end-users. Each deviation, however, costs in time, material and efficiency. End-users are advised to consider cost/benefit returns for each departure.

* The relation between end curves and dead-flat is determined by use. One extreme, no end curves and all dead-flat, produces a dock-like hull. The other extreme, no all curve and no dead-flat produces a constant 'rockered' bottom (easiest to move through water, but requires more time to build, generates more waste and reduces displacement and interior volume.

* The height of end curves is determined by use. High ends clear more waves, especially at the bow, and are suitable to sailing or exposed water hulls. Lower heights increase buoyancy and interior volume, and can be used in protected waters. A low or flat curve aft is consistent with planing hulls. There's a bit more to this that needs to be developed as an info module.

* Imperial System is recommended, unfortunately, unless using metric dimensioned sheets. This has to do with world standards for sheet dimensions generally being based on Imperial feet. Metric translations produce lengthy, non-mnemonic numbers which lead to miscommunication and error.

* The feet-inches-eighths system (a common standard in boat-building) helps simplify Imperial.

* Plywood sheets were the original inspiration, but the method is adaptable to any sheet material with maritime properties, such as steel and aluminum. Ply sheets are readily available in 4 x 8, 10, 12, 16 and 20 foot lengths (easy beam choices), though 4x8ft sheets are standard and the most economical. We've found select, AC grade to be sufficient.

* This rule-set should be supplemented by additional information regarding selecting scantlings, height of end curves, draft considerations, and various construction methods and options. As watercraft, they are subject to a much wider skillset for their safe operation.

* Rig and lateral resistance information packs need to be developed, as well as integration with GVCS PowerCubes and related propulsion.

== Product Ecology ==

=== From ===

A [[TriloBoat]] is assembled from sheet materials which include wood, wood composites, (bio)plastic composites, steel or aluminum. Each material may involve a different toolset, and can benefit from production by tools from the GVCS.

Wood based construction might thus involve the [[Dimensional Sawmill]] and/or [[Chipper]]. Metal based construction might involve [[Open Source Welder]] and [[Metal Roller]]. Composite contruction might involve the [[Bioplastic Extruder]].

=== Uses ===

Hardware, propulsion electronics, gear, outfit and accessories vary from extremely simple/minimal to highly advanced, and may use one to several tools from the GVCS.

For example, a landing-craft layout might use the [[Heat Exchanger]] to power the [[Modern Steam Engine]] to turn the [[Universal Rotor]]. [[Hydraulic Motors]] might be used for various PTO (Power Take Off) tasks, or run a modified [[Backhoe]] as a loading crane. The [[Nickle-Iron Battery]] to power shipboard electronics. A [[LifeTrac III]] might be carried to enhance longshoring capabilities.

== '''TriloBoat Overview''' ==

TriloBoats were designed by Dave Zeiger as a formula generated class of box barge (or scow) hulls based on construction from sheet materials.

The rules-of-thumb generate hundreds of instances in a wide array of sizes and functional layouts. Potential layouts include kayak, skiff, cargo carrier, tug, ferry, houseboat, cruiser and multihull. They are compatible with sail and power.

The rules-of-thumb are selected to simplify construction for dramatic savings in time, energy, material and money.

Triloboats are being offered as a starting point for the Open Source Boat (OSBoat)[http://opensourceecology.org/wiki/Open_Source_Boat].

With his partner, Anke Wagner, Dave has built three instances of TriloBoat, to date, including S/V SLACKTIDE, their home for the last three years. For further information, discussion, construction and sailing photos, please visit http://www.triloboats.com, and http://triloboats.blogspot.com.

== '''TriloBoat Hull Rules-of-Thumb''' ==

* Hulls are simple, box barges - rectangular in plan and section views.

* Hulls are constructed from whole and simple-fraction multiples of rectangular, off-the-shelf, sheet materials.

* Hull beam is one sheet.

* Hull length is scalable, generally in multiples (or combinations) of full length sheets.

* Hull curves are limited to the bottom ends (generally one quarter the LengthOfHull, curved in profile view) , reducing lofting, layout, spiling, cutting, beveling and bending to bare minimums.

* Hull curves are separated by a bottom dead-flat (planar section of bottom, generally one half the LengthOfHull).

* Hulls are self-rectifying and jig-less (consequences of these rules).

* All controlling numbers are rationalized (rounded), where possible, to maximize mnemonic retention, communication and accuracy.

== '''TriloBoat Superstructure Rules-of-Thumb''' ==

* Superstructures are constructed from whole and simple-fraction multiples of rectangular, off-the-shelf, sheet materials.

* Side decks are not used (flush decks maximize strength, simplify construction and assist ventilation).

* All decks are planar (sloped to drain), pitched or section-of-cylinder (simple layout and construction).

* Where section-of-cylinder decks are used, upper hull or superstructure are canted inboard to provide slack for a single sheet span of desired crown.

* All controlling numbers are rationalized (rounded), where possible, to maximize mnemonic retention, communication and accuracy.''

== '''TriloBoat Trade-Offs (Opposing Values)''' ==

* As one cuts away from the original ''prism'' (the rectangular slab formed by ''length'' x ''beam'' x ''draft''), one improves efficiency through the water (by reducing drag), but reduces interior volume and displacement.

* Narrow-for-length is faster through the water. Wide-for-length is slower, but more commodious and hauls more cargo for its length. I shoot for a length to beam ratio of 4:1, and compromise away in either direction, as needed.

* High end curves meet waves better, but reduce flat-water speed, displacement/buoyancy and interior volume.

* Every partial sheet generates lofting, cut-out and waste, but increases options. Simple fractions of sheets yielding round numbers (1, 1/2, 1/3, 1/4, 1/6, 1/8) generate less waste, and make for simple layout. Consider design for whole sheets where possible, and larger fractions where not.

* Curves take time, but add rigidity and reduce hull resistance, and in the superstructure shed water, add headroom and aesthetics. Consider using them sparingly where their benefits outweigh costs.

== '''TriloBoat Suggested Features''' ==

* Hull Divisions - 1/4 LengthOverAll as bow curve, 1/2 LengthOverAll as dead-flat (no bottom curve in profile view), and 1/4 LengthOverAll as aft curve. This allows easy end-curves while generating fully rectilinear mid-ships (simplifying construction of the interior and enabling modular furnishings), and allows easy blocking and transport by flat-bed.

* Locate a bulkhead at the division between dead-flat and end curve to simplify bending the bottom planking. Other bulkheads may be recommended along the hull length, depending on length and use.

* Box girder furnishings in the interior do much to stiffen the hull, and particularly the bottom.

* Plywood sheet construction with dimensional lumber framing (glued and nailed) is the fastest wood construction method. Sawn chine logs (from wide planks) at bow and stern are faster than bending, and require no steaming.

* External appendages (e.g., rudder, off-centerboards, skegs). This avoids complicated and weakening housings, wells and trunks. Much easier to dismount, inspect, maintain, modify and repurpose.

* Junk Rig - Easy to build, maintain and operate with short-handed crews. Low stress and fail safer. Minimal standing rigging. Flat cut sails require only rudimentary lofting and design. May use GVCS bioplastic fabric.

== '''Notes''' ==

* All 'rules' may be altered or ignored by end-users. Each deviation, however, costs in time, material and efficiency. End-users are advised to consider cost/benefit returns for each departure.

* The relation between end curves and dead-flat is determined by use. One extreme, no end curves and all dead-flat, produces a dock-like hull. The other extreme, no all curve and no dead-flat produces a constant 'rockered' bottom (easiest to move through water, but requires more time to build, generates more waste and reduces displacement and interior volume.

* The height of end curves is determined by use. High ends clear more waves, especially at the bow, and are suitable to sailing or exposed water hulls. Lower heights increase buoyancy and interior volume, and can be used in protected waters. A low or flat curve aft is consistent with planing hulls. There's a bit more to this that needs to be developed as an info module.

* Imperial System is recommended, unfortunately, unless using metric dimensioned sheets. This has to do with world standards for sheet dimensions generally being based on Imperial feet. Metric translations produce lengthy, non-mnemonic numbers which lead to miscommunication and error.

* The feet-inches-eighths system (a common standard in boat-building) helps simplify Imperial.

* Plywood sheets were the original inspiration, but the method is adaptable to any sheet material with maritime properties, such as steel and aluminum. Ply sheets are readily available in 4 x 8, 10, 12, 16 and 20 foot lengths (easy beam choices), though 4x8ft sheets are standard and the most economical. We've found select, AC grade to be sufficient.

* This rule-set should be supplemented by additional information regarding selecting scantlings, height of end curves, draft considerations, and various construction methods and options. As watercraft, they are subject to a much wider skillset for their safe operation.

* Rig and lateral resistance information packs need to be developed, as well as integration with GVCS PowerCubes and related propulsion.

== '''TriloBoat Hull Rules-of-Thumb''' ==

* Hulls are simple, box barges - rectangular in plan and section views.

* Hulls are constructed from whole and simple-fraction multiples of rectangular, off-the-shelf, sheet materials.

* Hull beam is one sheet.

* Hull length is scalable, generally in multiples (or combinations) of full length sheets.

* Hull curves are limited to the bottom ends (generally one quarter the LengthOfHull, curved in profile view) , reducing lofting, layout, spiling, cutting, beveling and bending to bare minimums.

* Hull curves are separated by a bottom dead-flat (planar section of bottom, generally one half the LengthOfHull).

* Hulls are self-rectifying and jig-less (consequences of these rules).

* All controlling numbers are rationalized (rounded), where possible, to maximize mnemonic retention, communication and accuracy.

== '''TriloBoat Superstructure Rules-of-Thumb''' ==

* Superstructures are constructed from whole and simple-fraction multiples of rectangular, off-the-shelf, sheet materials.

* Side decks are not used (flush decks maximize strength, simplify construction and assist ventilation).

* All decks are planar (sloped to drain), pitched or section-of-cylinder (simple layout and construction).

* Where section-of-cylinder decks are used, upper hull or superstructure are canted inboard to provide slack for a single sheet span of desired crown.

* All controlling numbers are rationalized (rounded), where possible, to maximize mnemonic retention, communication and accuracy.''

== '''TriloBoat Trade-Offs (Opposing Values)''' ==

* As one cuts away from the original ''prism'' (the rectangular slab formed by ''length'' x ''beam'' x ''draft''), one improves efficiency through the water (by reducing drag), but reduces interior volume and displacement.

* Narrow-for-length is faster through the water. Wide-for-length is slower, but more commodious and hauls more cargo for its length. I shoot for a length to beam ratio of 4:1, and compromise away in either direction, as needed.

* High end curves meet waves better, but reduce flat-water speed, displacement/buoyancy and interior volume.

* Every partial sheet generates lofting, cut-out and waste, but increases options. Simple fractions of sheets yielding round numbers (1, 1/2, 1/3, 1/4, 1/6, 1/8) generate less waste, and make for simple layout. Consider design for whole sheets where possible, and larger fractions where not.

* Curves take time, but add rigidity and reduce hull resistance, and in the superstructure shed water, add headroom and aesthetics. Consider using them sparingly where their benefits outweigh costs.

== '''TriloBoat Suggested Features''' ==

* Hull Divisions - 1/4 LengthOverAll as bow curve, 1/2 LengthOverAll as dead-flat (no bottom curve in profile view), and 1/4 LengthOverAll as aft curve. This allows easy end-curves while generating fully rectilinear mid-ships (simplifying construction of the interior and enabling modular furnishings), and allows easy blocking and transport by flat-bed.

* Locate a bulkhead at the division between dead-flat and end curve to simplify bending the bottom planking. Other bulkheads may be recommended along the hull length, depending on length and use.

* Box girder furnishings in the interior do much to stiffen the hull, and particularly the bottom.

* Plywood sheet construction with dimensional lumber framing (glued and nailed) is the fastest wood construction method. Sawn chine logs (from wide planks) at bow and stern are faster than bending, and require no steaming.

* External appendages (e.g., rudder, off-centerboards, skegs). This avoids complicated and weakening housings, wells and trunks. Much easier to dismount, inspect, maintain, modify and repurpose.

* Junk Rig - Easy to build, maintain and operate with short-handed crews. Low stress and fail safer. Minimal standing rigging. Flat cut sails require only rudimentary lofting and design. May use GVCS bioplastic fabric.

== '''Notes''' ==

* All 'rules' may be altered or ignored by end-users. Each deviation, however, costs in time, material and efficiency. End-users are advised to consider cost/benefit returns for each departure.

* The relation between end curves and dead-flat is determined by use. One extreme, no end curves and all dead-flat, produces a dock-like hull. The other extreme, no all curve and no dead-flat produces a constant 'rockered' bottom (easiest to move through water, but requires more time to build, generates more waste and reduces displacement and interior volume.

* The height of end curves is determined by use. High ends clear more waves, especially at the bow, and are suitable to sailing or exposed water hulls. Lower heights increase buoyancy and interior volume, and can be used in protected waters. A low or flat curve aft is consistent with planing hulls. There's a bit more to this that needs to be developed as an info module.

* Imperial System is recommended, unfortunately, unless using metric dimensioned sheets. This has to do with world standards for sheet dimensions generally being based on Imperial feet. Metric translations produce lengthy, non-mnemonic numbers which lead to miscommunication and error.

* The feet-inches-eighths system (a common standard in boat-building) helps simplify Imperial.

* Plywood sheets were the original inspiration, but the method is adaptable to any sheet material with maritime properties, such as steel and aluminum. Ply sheets are readily available in 4 x 8, 10, 12, 16 and 20 foot lengths (easy beam choices), though 4x8ft sheets are standard and the most economical. We've found select, AC grade to be sufficient.

* This rule-set should be supplemented by additional information regarding selecting scantlings, height of end curves, draft considerations, and various construction methods and options. As watercraft, they are subject to a much wider skillset for their safe operation.

* Rig and lateral resistance information packs need to be developed, as well as integration with GVCS PowerCubes and related propulsion.

Dave Zeiger: Proposing TriloBoats as OSBoat

Hi Folks,

My name is Dave Zeiger, designer of ''TriloBoats''.

TriloBoats were designed by me as a formula generated class of box barge (or scow) hulls based on construction from sheet materials.

The rules-of-thumb generate hundreds of instances in a wide array of sizes and functional layouts. Potential layouts include kayak, skiff, cargo carrier, fishboat, tug, ferry, houseboat, cruiser and multihull. They are compatible with sail and power.

The rules-of-thumb are selected to simplify construction for dramatic savings in time, energy, material and money.

A wiki, http://opensourceecology.org/wiki/Triloboat, has been started to introduce the concept, which I hope to see developed as the OSBoat.

Looking forward to collaborating with you!

Dave Z.

For further information on TriloBoats, please see my site at http://www.triloboats.com and blog at http://triloboats.blogspot.com.

Dave Zeiger: /* TriloBoat Hull Rules-of-Thumb */ Specify BOTTOM curves

[[File:T32x8 CARGO Sample.jpg|center|600px]]
<center>'''Sample TriloBoat Instance: T32x8 with typical cargo layout.'''</center>

== '''TriloBoat Overview''' ==

TriloBoats were designed by Dave Zeiger as a formula generated class of box barge (or scow) hulls based on construction from sheet materials.

The rules-of-thumb generate hundreds of instances in a wide array of sizes and functional layouts. Potential layouts include kayak, skiff, cargo, houseboat, cruisers and multihulls. They are compatible with sail and power.

The rules-of-thumb are selected to simplify construction for dramatic savings in time, energy, material and money.

With his partner, Anke Wagner, Dave has built three instances of TriloBoat, to date, including S/V SLACKTIDE, their home for the last three years. For further information, discussion, construction and sailing photos, please visit http://www.triloboats.com, and http://triloboats.blogspot.com.

== '''TriloBoat Hull Rules-of-Thumb''' ==

* Hulls are simple, box barges - rectangular in plan and section views.

* Hulls are constructed from whole and simple-fraction multiples of rectangular, off-the-shelf, sheet materials.

* Hull beam is one sheet.

* Hull length is scalable, generally in multiples (or combinations) of full length sheets.

* Hull curves are limited to the bottom ends (generally one quarter the LengthOfHull, curved in profile view) , reducing lofting, layout, spiling, cutting, beveling and bending to bare minimums.

* Hull curves are separated by a bottom dead-flat (planar section of bottom, generally one half the LengthOfHull).

* Hulls are self-rectifying and jig-less (consequences of these rules).

* All controlling numbers are rationalized (rounded), where possible, to maximize mnemonic retention, communication and accuracy.

== '''TriloBoat Superstructure Rules-of-Thumb''' ==

* Superstructures are constructed from whole and simple-fraction multiples of rectangular, off-the-shelf, sheet materials.

* Side decks are not used (flush decks maximize strength, simplify construction and assist ventilation).

* All decks are planar (sloped to drain), pitched or section-of-cylinder (simple layout and construction).

* Where section-of-cylinder decks are used, upper hull or superstructure are canted inboard to provide slack for a single sheet span of desired crown.

* All controlling numbers are rationalized (rounded), where possible, to maximize mnemonic retention, communication and accuracy.''

== '''TriloBoat Trade-Offs (Opposing Values)''' ==

* As one cuts away from the original ''prism'' (the rectangular slab formed by ''length'' x ''beam'' x ''draft''), one reduces interior volume and displacement while reducing resistance through the water.

* High end curves meet waves better, but reduce flat-water speed, displacement and buoyancy, and interior volume.

* Every partial sheet generates lofting, cut-out and waste, but increase options. Simple fractions of sheets yielding round numbers (1, 1/2, 1/3, 1/4, 1/6, 1/8) generate less waste, and make for simple layout. Consider design for whole sheets where possible, and larger fractions where not.

* Curves take time, but add rigidity and reduce hull resistance, and in the superstructure shed water, add headroom and aesthetics. Consider using them sparingly where their benefits outweigh costs.

* Narrow-for-length is faster through the water. Wide-for-length is slower, but more commodious and hauls more cargo for its length. I shoot for a length to beam ratio of 4:1, and compromise away in either direction, as needed.

== '''TriloBoat Suggested Features''' ==

* Hull Divisions - 1/4 LengthOverAll as bow curve, 1/2 LengthOverAll as dead-flat (no bottom curve in profile view), and 1/4 LengthOverAll as aft curve. This allows easy end-curves while generating fully rectilinear mid-ships (simplifying construction of the interior and enabling modular furnishings), and allows easy blocking and transport by flat-bed.

* Locate a bulkhead at the division between dead-flat and end curve to simplify bending the bottom planking. Other bulkheads may be recommended along the hull length, depending on length and use.

* Box girder furnishings in the interior do much to stiffen the hull, and particularly the bottom.

* Plywood sheet construction with dimensional lumber framing (glued and nailed) is the fastest wood construction method. Sawn chine logs (from wide planks) at bow and stern are faster than bending, and require no steaming.

* External appendages (e.g., rudder, off-centerboards, skegs). This avoids complicated and weakening housings, wells and trunks. Much easier to dismount, inspect, maintain, modify and repurpose.

* Junk Rig - Easy to build, maintain and operate with short-handed crews. Low stress and fail safer. Minimal standing rigging. Flat cut sails require only rudimentary lofting and design. May use GVCS bioplastic fabric.

== '''Notes''' ==

* All 'rules' may be altered or ignored by end-users. Each deviation, however, costs in time, material and efficiency. End-users are advised to consider cost/benefit returns for each departure.

* The relation between end curves and dead-flat is determined by use. One extreme, no end curves and all dead-flat, produces a dock-like hull. The other extreme, no all curve and no dead-flat produces a constant 'rockered' bottom (easiest to move through water, but requires more time to build, generates more waste and reduces displacement and interior volume.

* The height of end curves is determined by use. High ends clear more waves, especially at the bow, and are suitable to sailing or exposed water hulls. Lower heights increase buoyancy and interior volume, and can be used in protected waters. A low or flat curve aft is consistent with planing hulls. There's a bit more to this that needs to be developed as an info module.

* Imperial System is recommended, unfortunately, unless using metric dimensioned sheets. This has to do with world standards for sheet dimensions generally being based on Imperial feet. Metric translations produce lengthy, non-mnemonic numbers which lead to miscommunication and error.

* The feet-inches-eighths system (a common standard in boat-building) helps simplify Imperial.

* Plywood sheets were the original inspiration, but the method is adaptable to any sheet material with maritime properties, such as steel and aluminum. Ply sheets are readily available in 4 x 8, 10, 12, 16 and 20 foot lengths (easy beam choices), though 4x8ft sheets are standard and the most economical. We've found select, AC grade to be sufficient.

* This rule-set should be supplemented by additional information regarding selecting scantlings, height of end curves, draft considerations, and various construction methods and options. As watercraft, they are subject to a much wider skillset for their safe operation.

* Rig and lateral resistance information packs need to be developed, as well as integration with GVCS PowerCubes and related propulsion.

<center>'''Sample TriloBoat Instance: T32x8 with typical cargo layout.'''</center>

== '''TriloBoat Overview''' ==

TriloBoats were designed by Dave Zeiger as a formula generated class of box barge (or scow) hulls based on construction from sheet materials.

The rules-of-thumb generate hundreds of instances in a wide array of sizes and functional layouts. Potential layouts include kayak, skiff, cargo, houseboat, cruisers and multihulls. They are compatible with sail and power.

The rules-of-thumb are selected to simplify construction for dramatic savings in time, energy, material and money.

With his partner, Anke Wagner, Dave has built three instances of TriloBoat, to date, including S/V SLACKTIDE, their home for the last three years. For further information, discussion, construction and sailing photos, please visit http://www.triloboats.com, and http://triloboats.blogspot.com.

== '''TriloBoat Hull Rules-of-Thumb''' ==

* Hulls are simple, box barges - rectangular in plan and section views.

* Hulls are constructed from whole and simple-fraction multiples of rectangular, off-the-shelf, sheet materials.

* Hull beam is one sheet.

* Hull length is scalable, generally in multiples (or combinations) of full length sheets.

* Hull curves are limited to the ends (generally one quarter the LengthOfHull) , reducing lofting, layout, spiling, cutting, beveling and bending to bare minimums.

* Hull curves are separated by a dead-flat (planar section of bottom, generally one half the LengthOfHull).

* Hulls are self-rectifying and jig-less (consequences of these rules).

* All controlling numbers are rationalized (rounded), where possible, to maximize mnemonic retention, communication and accuracy.''''

== '''TriloBoat Superstructure Rules-of-Thumb''' ==

* Superstructures are constructed from whole and simple-fraction multiples of rectangular, off-the-shelf, sheet materials.

* Side decks are not used (flush decks maximize strength, simplify construction and assist ventilation).

* All decks are planar (sloped to drain), pitched or section-of-cylinder (simple layout and construction).

* Where section-of-cylinder decks are used, upper hull or superstructure are canted inboard to provide slack for a single sheet span of desired crown.

* All controlling numbers are rationalized (rounded), where possible, to maximize mnemonic retention, communication and accuracy.''

== '''TriloBoat Trade-Offs''' ==

* As one cuts away from the original ''prism'' (the rectangular slab formed by ''length'' x ''beam'' x ''draft''), one reduces interior volume and displacement while reducing resistance through the water.

* High end curves meet waves better, but reduce flat-water speed, displacement and buoyancy, and interior volume.

* Every partial sheet generates lofting, cut-out and waste, but increase options. Simple fractions of sheets yielding round numbers (1, 1/2, 1/3, 1/4, 1/6, 1/8)generate less waste, and make for simple layout. Consider design for whole sheets where possible, and larger fractions where not.

* Curves take time, but reduce hull resistance, and in the superstructure shed water, add headroom and aesthetics. Consider using them sparingly where their benefits outweigh costs.

* Narrow-for-length is faster through the water. Wide-for-length is slower, but more commodious and hauls more cargo for its length. I shoot for a length to beam ratio of 4:1, and compromise away in either direction, as needed.

== '''TriloBoat Suggested Features''' ==

* Hull Divisions - 1/4 LengthOverAll as bow curve, 1/2 LengthOverAll as dead-flat (no bottom curve in profile view), and 1/4 LengthOverAll as aft curve. This allows easy end-curves while generating fully rectilinear mid-ships (simplifying construction of the interior and enabling modular furnishings), and allows easy blocking and transport by flat-bed.

* Locate a bulkhead at the division between dead-flat and end curve to simplify bending the bottom planking. Other bulkheads may be recommended along the hull length, depending on length and use.

* Box girder furnishings in the interior do much to stiffen the hull, and particularly the bottom.

* Plywood sheet construction with dimensional lumber framing (glued and nailed) is the fastest wood construction method. Sawn chine logs (from wide planks) at bow and stern are faster than bending, and require no steaming.

* External appendages (e.g., rudder, off-centerboards, skegs). This avoids complicated and weakening housings, wells and trunks. Much easier to dismount, inspect, maintain, modify and repurpose.

* Junk Rig - Easy to build, maintain and operate with short-handed crews. Low stress and fail safer. Minimal standing rigging. Flat cut sails require only rudimentary lofting and design. May use GVCS bioplastic fabric.
