Basics

- An open source boat powered primarily by sail power

- Is a part of the Open Source Watercraft Construction Set

- Is easily maintainable (unlike many sailboats today)



Used for

- Transportation of People

- Transportation of Goods

- Open Water Fishing

- Open Water Farming of Water Based Plant Life (i.e Seaweed)

- Recreation



Industry Standards

- Aquafin Daysailer

- Aquafin Sunfish

- Laser

- ETAP Yachts



Existing Open Source Designs

- "Ceres" class Barge, in Sail Freighter Handbook 2ed.

- TriloBoat: https://wiki.opensourceecology.org/wiki/Triloboat

Minimum Viable Product

- Open Source

- Modular

- User Maintainable (Easily)

- User Upgradable

- Scaleable ( A 5 Meter Aquafin/Laser Clone all the way to a massive yacht over 20 Meters )

- Has an inboard hydraulic pump-jet motor powered by a "PowerCube Array"

- Electric/Bio-diesel/DME Powered Power Cubes

- User Collapsible Mast

- Unsinkable (i.e filled with a foam like material see this

- Is much cheaper while still retaining quality

- Optional Automation

- Larger versions contain all major utilities (Water (Both Stored and Made on Board) , Ac+DC Power, Networking, Communication, etc. )

- Pump Jet Powered Maneuvering Thrusters

- Centralized Cathodic Protection



Basic Design

Hull

- Fiberglass or Composite

- Printed in One Piece Using The Open Source Watercraft Hull Printer

- Plywood and Steel are an easy to work and well understood set of options.


Weighted Keel

- This prevents it from tipping over

- Need to decide what metal to use (Lead in a steel box is traditional)

- Would we want two hull layers with this "sandwiched" in between possibly?


Mast

- A mast with no stays (Stayed rig adds significant benefits for safety and force distribution over the vessel while not adding significant complexity)

- Should also be able to telescope, or fold down for storage, or going under bridges (and do this without cranes etc) (The component for this is termed a Tabernacle)


Powercube Array

- Provides power for the hydraulic engines (Both for thrust when not using sails (such as when docking), and for bow thrusters if used)


IO
