ABSTRACT:
A water ski fin is carried by a housing mounted to the upper surface of the rear end of a ski with the fin extending downwardly through an elongated slot in the ski. The fin carries a transversely extending wing thereon and the combination is capable of being pivoted relative to the housing and ski to thereby change the angle of the wing. Movement is accomplished by a handle on one side of the housing which rotates a cam element which, in turn, engages an opening in the fin adjacent the top thereof. A locking device maintains the wing and fin in the desired position by preventing further movement of the cam element.
