Mast and Sail
If a canoe is outfitted with a mast and sail, it should also have outriggers. Otherwise, it can easily be toppled by the wind.
The mast is roughly 4 meters160 in long and tapers from 28 mm1.125 inches at the top to 45 mm1.75 in at the bottom. It is inserted into a hole in the seat, and then into a socket cut into the bottom of the boat to receive it.
A few inches above the seat it is fastened to a boom. The boom is the same length and diameter as the mast. Shoulders are cut near both ends, with the mast-end having a deeper shoulder (see illustration).
The boom is simply tied to the mast, and the sail is tied to both the mast and the boom. The sail itself is triangular.

Choose a soft wood and shape the model as closely as you can to match your canoe. People will often carve a scale model before beginning to shape the log. The model can then be used as a reference.
