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.

An adjustable water ski fin and wing assembly comprising: a shallow substantially rectangularly shaped mounting means, said mounting means being adapted to overlie an elongated longitudinally extending slot in the rear end of a water ski; means for securing said mounting means to the upper surface of said ski; a fin including a top edge lying substantially totally within said mounting means and extending downwardly therefrom through said slot; a pivot pin located adjacent said top edge of said fin for pivotally fastening said fin to said mounting means, said pin extending transversely of said mounting means; a wing extending outwardly from either side of said fin and substantially perpendicular thereto; means for manually pivoting said fin including a first cam element located within said mounting means and including a handle portion extending to the exterior of said mounting means and a second cam element carried by said fin adjacent one end of said top edge in cooperative relationship with said first cam element, and means for locking said fin to prevent pivotal movement thereof.
