ABSTRACT:
A slalom water-ski training device comprising a main channel member having a vertical upright member that is rigidly mounted substantially perpendicular thereto at one end thereof. At least two auxiliary support braces are connected at one end to the vertical upright member and connected at their opposite end to the main channel member. At least one stabilizing member is rigidly connected to and in substantial coplanar relation with the main channel member a proximate predetermined distance from the vertical upright member. A ski rope is detachably and reattachably connected to the vertical upright member at a free end distal the main channel member. A ski board is slidably and swivelly mounted to the main channel member. A resilient sliding resistance means is attached to the main channel member distal the vertical upright member and the ski board for the purpose of applying a substantially elastic resistance to the sliding longitudinal displacement of the ski board. An angle plate is pivotally mounted to the main channel member for varying the pitch angle of the ski board relative to the main channel member. The angle plate has a top and two sides, each side having a front portion and a rear portion. Each front portion has a plurality of coaxial apertures therein for insertion of a locking pin therethrough. Each rear portion has a coaxial aperture therein for insertion of a locking pin therethrough. The present invention also includes a strain gage connected to the free end of the vertical upright member for measuring a force exerted on the ski rope by a skier using the invention.
