This design is a modern interpretation of the traditional Koa fishing canoes which were 'dugouts' and made from a single log. The hull has a narrow flat bottom with 4 planks per side - the top hull panel has some tumblehome in it to emulate the log shape. Plank lengths fit within 2 standard 8' (2440mm) lengths of plywood. The hull is symmetrical about the centre frame and details are given to make the hull in 2 bolt able halves. This also means that the hull can be extended by fitting a section in the middle of the hull - potentially, using standard plywood sheets an 8' section could be inserted making the canoe 23'4" long.
Details are given for the Ama and beams used with the 18' Waka Ama.
Construction is simple stitch and tape and the beams are tied to the hulls.
