ABSTRACT:
A vehicular snow ski is disclosed having an ultra high molecular weight polymer material for extended wear and an adjustable curvature tip end. The tip end is adjustable using a variable length turnbuckle for controlling the curvature and tension of the curved tip end. The radius of the curved tip end is changed to meet varying snow conditions encountered by an operator. The under surface of the ski includes a plurality of concave surfaces extending longitudinally therealong for compacting snow and lifting the ski in the snow when moving therein. Two concave surfaces are recessed from a center concave surface to form two vertically oriented steering surfaces for controlling the direction of the ski in opposite directions. A wear bar with carbide inserts extends beyond the center concave surface for running on ice and other hard surfaces. Attached to the top surface is a shoe for mounting the ski to the suspension of a vehicle such as a snowmobile.
