There are many other interesting and easy to build sailing canoes on the outrigger Sailing Canoes website so please take a look.
The Wa'apa is a three board canoe that is very simple to built. A three board canoe is so named because that is how it is built. There are a couple of designs for this boat including a shunting version and a tacking version. It is also possible to build the boat such that it can be broken into 8 foot sections that bolt together at bulkheads.
We would plan to build two identical boats that would have the capability to be sailed or paddled individually or connected and sailed together in a catamaran configuration for use in our 4 man team entry in the Everglades Challenge in 2007.
