ABSTRACT:
An improved wind-propelled ski apparatus which comprises a ski, risers and deck. The risers comprise upper and lower platforms and connecting positioned members between the platforms. The risers are attached to the ski and provide an elevated surface for the installation of a deck, where the rider's feet are positioned. The elevation of the rider's feet provides greater control of the ski and protection for the rider's feet. The ski is an elongated, planar member having a series of openings along its length for the attachment of a sail mount and the risers. The openings can accommodate the risers and the sail mount in various positions on the ski to adapt to the needs of the rider.
