I made the kids their own model outrigger sailing canoes. Made them out of styrofoam trays, electrical tape and bamboo skewers. They sailed really well, but they need more forward buoyancy.
They aren't true "proas" becuase they have a directional bias (with a rudder on the back) - real proas "shunt" instead of tack/jibe to move through the wind. Shunting is just going back the other way (hopefully with some ground gained).
The next set I build will have bigger (or at least wider) bows and longer (with a forward bias) amas.
