The
Tamanu is a "three
board"
canoe with a flat bottom and moderate rocker. The
hull can be quickly and easily constructed with 1/4" or 3/16" plywood.
The ama or amas can be foam and fiberglass or hollow plywood. The most important difference between the Tamanu and my other designs is the self bailing footwells. The hull is completely decked over with self bailing footwells or a larger self bailing cockpit making it suitable for more ambitious cruising. The Tamanu can be configured with a single outrigger, double outrigger, or as a catamaran.
The rig style is tacking only and a kick-up rudder is mounted on the stern or on the side. A pivoting leeboard is mounted on the side of the hull. There are two rig options shown in the plans; the first can be reefed by rolling the sail around the windsurf mast. The second option uses a stub mast that is used to raise and lower the yard and sail. However, Tamanus have successfully used lug rigs, junk rigs, sprit rigs, gaff rigs and windsurf rigs. While my other designs are cartoppable, the Tamanu is almost too large and heavy to be transported on a car roof. Heavier racks on a pickup truck or a trailer is recommended.
