The aluminum skeleton inside the hull will hold all the critical parts together – the sail, keel, rudder and wind sensor. Precise cutting, milling and welding were beyond my skills, so different craftsmen and fablab did an amazing job helping me build a really robust skeleton.
The skeleton is secured with carbon/Kevlar and waterproofed with epoxy putty. The tubes that stick from the sides of the hull are for lifting the boat out of the water. They can also be used for attaching side floats and converting the boat into a trimaran (just in case).
