The effects of a side-cut of skis on ski turns were investigated in ski descent experiments using model skis on soft sand surfaces of various thicknesses. The side-cut shapes of the model skis are linear, reel, and barrel types. When the sand was thick and the tracks of the descending ski remained on the sand surface, the effect of the side-cut was very small. When the sand was extremely shallow and only faint tracks of the edge of the ski remained on the sand surface, the effect of the side-cut was large. The shallow sand surface is considered to be equivalent to a hard snow surface such as an icy slope. When the ski is edged on a sand surface, the surface is deformed according to the shape of the edged ski. The turning mechanism of linear-type skis is explained using the deformation of the sand surface.
