I think I made about 6-7 models with paper and cardboard.
I’ve finally tweaked the design to where I’m happy and brave enough to start cutting real wood.
After modifications I’m looking at a max beam around 33″ and total length of 13’1 (I think that’s what I remember)
I know there will be some issues as scaling 2d parts doesnt necessarily make sense for a complex 3d object.
Of course the bulkheads had to be modified to support a cockpit. And the sides raised to be more kayak like.
