Abstract
A wind propelled apparatus is disclosed which includes a surfboard having a wind-propulsion sail adapted to receive wind for motive power, and a training sleeve which surrounds a substantial portion of the surfboard and includes side pontoons or stabilizer tanks filled with air under pressure to stabilize the surfboard with respect to a longitudinal axis. The training sleeve is preferably of a woven fabric which is maintained in tension and snugly against the board and has a relatively non-skid surface for stepping by an operator. This function is useful in combination with the stabilizer tanks particularly as a training aid for novice operators, but may also be used as desired by experienced operators under extreme conditions.
