Below is the link to an interesting article about a small trimaran currently under development. The idea is to create open source building plans of this boat for use by high schools (and others).
“After some trial and error, the Kiss project took the shape of a 6.60 meter long and 3.20 meter wide canoe. A sort of trimaran with enough volume in the hull and floats for fun under sail, and light enough to reduce drag when paddling. The target weight is less than 200 kg.
The Kiss dugout can accommodate 3 people and can be easily dismantled. The 4 arms are fixed by interlocking systems with pins and dowels.”
