ABSTRACT:
A mono-ski for alpine skiiing to which both of the skier's boot bindings are mounted such that the skier's boots are side by side, close together and both facing forward. The widest part of the forward or shovel area of the mono-ski is thirty percent or more wider than the narrowest part of the central or waist area of the mono-ski. The mono-ski has concave side-cuts which are three-quarters of an inch or more. The forward or shovel area of the mono-ski slopes gradually upward over at least the forward fifteen percent and the rear or tail area slopes gradually upward over at least the rear seven percent of the total length of the mono-ski. The skier's boots are positioned rearward of the center, the thickness of the mono-ski is greatest at the central or waist area, the bottom is flat transversely without grooves and the mono-ski has camber. The bottom running surface should be of polyethylene or similar material. It is desirable that the top surface also be of the same material, to have bottom metal edges, interior reinforcing plates under the boot bindings and a protective metal insert in the tail of the mono-ski. The mono-ski can be made by methods and of materials commonly used in the industry.
