Proa... or at least the ama for now.

Simple drawing:
Length is about 9.5m so it fits standard plywood sheets 4x8 feet. The ama is half that.
Ama is 4mm marine ply and the waka should be made from 7mm.
I used the Carlsson program for the plywood projections but I had to make two main hulls with the same sideview to get the asymmetrical hull.

Also in the end a little roof 11x3m that we put in the garden to provide some space with shadow and protection from rain. That will be ok for building the main hull.
