ABSTRACT:
Equipment for towless skiing on water surface includes a pair of propulsion sticks having buoyant members at one end and handles at the other end. The buoyant members provide increased thrust against the hydrodynamic resistance of the water, and the shape of the buoyant members permits removal of the buoyant members from the water with little resistance. The equipment also includes a pair of skis comprised of foam material and provided with stabilizing shoulders on both sides of each ski for minimizing the effect of nose diving and rolling of the skis in the surf. The cross-sectional areas of the buoyant members and of the skis are such that maximum propulsion forces are provided. The skis are designed to endow the surf skier with a greater degree of freedom during surf skiing and to enable the skier to ski for longer distances on the water.
