Tarawa, A Proa for One

Rig Details
Tarawa was designed to test sail rigs, hull shapes and steering systems to be used with shunting canoes.  At 16' (4.8 M) is is small enough to disassemble and transport on a roof rack.  Hull construction is strip composite with redwood strips and epoxy/glass skins.  Crossarms are recycled aluminum mast extrusions.  The outrigger float (ama) has a hollow box core of wood with additional polyurethane foam and fiberglass on the outside.  Two rigs have been tested; the classic Oceanic lateen and a variation of the rig used by Euell Gibbons in Hawaii in the 1950's.  The classic rig requires a little more effort in shunting but performs well with a very low center of effort.  The Gibbons rig is an attempt to simplify the shunting procedure and does not require the sailor to move to the ends of the canoe.  Testing has recently begun with special attention to stability during the shunt.  Steering closehauled and beam reaching is accomplished by slight shifts in crew weight.  A steering oar is used for broad reaches and running.  Lateral resistance is obtained through the vee-ed asymmetrical hull.
