ABSTRACT:
A substantially rigid ski is provided to afford high degrees of maneuverability and stability. The bottom surface of the ski is convex from front to rear and convex from side to side. The ski has a maximum effective width substantially in line with the pivot point over which the skier's weight will be centered. The ski assumes a narrower effective width both forward and rearward of the pivot point and then assumes an intermediate effective width closer to the front and rear respectively. The narrower effective width can be achieved by a narrower actual width, a greater degree of convexity or by a combination of the two. The bottom surface includes well defined bottom side edges that are substantially parallel to the top surface of the ski. The sides of the ski are concave adjacent the bottom side edges.
