This boat is made from one sheet of 4mm marine ply for the sides, one sheet of 6mm marine ply, for the bottom and some sticks, fibreglass and epoxy to stop the thing from falling apart and to give yourself somewhere moderately comfortable to sit.
Most of the layout for this example comes from free sources on the web which I will include reference to where I deem I feel like it, but the main one is the lazy weekend canoe from the Toledo Community Boathouse
This design is 6/7 of a Lazy weekend canoe, being 12 rather than 14 inches high and built using only 2 sheets of plywood instead of 3.
The canoe is a basic plan intended for two people and fishing gear on calm waters. Emergency floatation will be pool noodles tied under the seats and a custom made beanbag cushion for the center. The back seat has a low back rest but the front is intended to be used in reverse when paddled single handed.
In this layout it would traditionally be propelled by two people with one ended paddles paddling one side each. Two ended paddles can be used but to clear the sides easily you might need to make an extra long one. "Real" two ended paddlers will fit the length of the paddle to the person rather than the boat, which is fine till you are paddling something too wide for how you are tall. More on this in step 17 - water trials.
This is the perfect boat to use for your uke'n'paddle.
