Abstract
Abstract A seat affixed to an extra wide ski for use primarily by paraplegics for the sport of water skiing. The seat is comprised of a tubular framework with a fabric sling-type seat which supports the rider in a forward angled seated position with the knees drawn up towards the chest. Padded front and side rails prevent forward and lateral movement of the rider's buttocks. Frictional fit of the rider's buttocks between the padded side rails and placement of the knees and legs over the front rail secure the rider in position without the use of belts or straps. The tubular framework is affixed to a base which is connected to the central top surface of the sky by bolts. Foot bindings are affixed to the forward top surface of the ski to removably retain the rider's feet.
