There have been a few canoe like objects put up on instructables but this one is really a pirogue- or flat bottom canoe. There is actually a lot of theory on boats like this one but the basic idea is you take two planks, stick them together at the ends with a frame or two in the middle, fill in the hole in the bottom with another plank and then add decks and thwarts and yokes and outriggers and sails and whatever else you feel like.
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 something like pool noodles tied under the seats and a 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.
The woodworking skills required here are minimal and if you use epoxy, any mistakes are easily covered up, or filled.
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.
