ABSTRACT:
A water ski with a short and broad ski body and having a forebody, midbody, and tail rocker and a top and bottom surface. Affixed to the top surface is foot binding having a right and left boot. The right and left boot are mounted on the right and left side respectively of the longitudinal centerline of the ski body by means of a binding plate which is adjustable either forward or rearward on the ski body. Just behind the heel clamp of the binding assembly is the transverse center of the stabilizing fin. The fin blade protrudes through a slot in the ski body downward through the ski body. The fin is affixed to the top surface of the ski body by the fin fixing flange. The bottom surface of the ski body has a bevel along the entire perimeter and a concave tunnel that begins at the tail and ends at the forbody. Between the bevel and concave tunnel is a flat rail the is generally parallel to the top surface of the ski body. The ski is intended to perform as a trick ski because of its short length, light weight, and side by side binding configuration. It also is intended for use as a slalom ski due to its short length and therefore short turning radius and the mounting of the fin just behind the heel thereby requiring less leverage to initiate slalom turns. The ski also provides a stance very similar to that of snow skiing and therefor may be used to practice snow skiing during the off-season.
