Here's a 12 foot long outrigger sailing canoe I built in Kenya this spring.
It has folding "beds" for two, a removable roof, and a sail.
It's easy to build.
The only tools needed were a machete, knife, drill, chisel, spokeshave, hammer, screwdriver.
Here Nathan Eagle, Eddie Elliot, and myself get the boat ready to launch.

Step 1: Specifications
All measurements are actual not milled.
The wood species names are what the locals call them. The wood is grown locally and probably not related to the species we call by the same name. Their "cedar" is heavier and stronger than ours.
The hull is 12' 2" overall, made from 6mm cypress plywood joined with 3/4" cedar sticks at the edges. The hull is 18" deep, 18" wide in the middle. The stems are 2'x4" cedar carved into a wedge shape. The stems stand tall and the front one is carved into a dog's head.
The crossbeams are 2x2" square pine, 102" long.
The outrigger floats are 1" thick pine boards 127" long, carved to an upturned point at the front.
The mast is a 12 foot pine 2x2 shaved into an octagon shape, tapered down to a 2" diameter rod at both ends. The sprit is 1" square.
The sail is a 6' square shower curtain rigged as a spritsail. They don't have polytarp in kenya, and tarp like things are expensive.
