ABSTRACT:
The water ski board of the present invention is a generally flat U-shaped board with an upward curvature at its forward end portion. Two short tails extend backward from the body of the board slightly forward of which is fixed a pair of foot bindings. The tails are of greater thickness than the board with a taper beginning at the front of each tail. A U-shaped channel with a plurality of holes provided along its length is affixed to the top of the board along its center axis to permit the tow line to be attached at any of the holes. The variable attachment of the tow lines allows the board to plane at different speeds, depending on the weight of the rider in relationship to the direction of pulling force from the boat. On the bottom surface of each tail a semicircular tunnel is formed at the approximate center running parallel to the axis. On both sides of the tunnel a tube runs through the length of the tail parallel to the axis. The tube is open at both ends so that water enters the front of the tube at the taper of the tail and exits from the back of the tail. A fin is located in the center of the board on the axis on the bottom surface, slightly forward of the tails.
