Some great design work has gone into this.. For a week or two summer vacation where you assemble when you arrive and pack up at the end of the trip it would be perfect.
im thinking about used ripstop truck cover fabric to make a foldable skin-on-frame boat, the frame should use practical clamps system and the use of tension ropes could be used also with bowtegrity (a type of tensegrity) both longitudinaly and cross sectional to reduce compression frame weight and improve stiffness
theres a lot of savings by using ropes por tension for three axis, this boat also could have made with a foldying frame made of reclaimed wood supported by ropes and some upcycled truck cover ripstop fabric
