    Abstract

    This invention is directed toward a fin box capable of accepting either a Futures® or an FCS® fin without the need for any additional products being added to either the fins or the fin box. The box has an internally-adjustable wedge that can force the bottom of a fin into an indent, thereby giving it a cant or angle. The box also has channels for both FCS® and Futures® fins, such that a user can easily exchange either brand of fin without adding or subtracting items from the fins or fin boxes. Another embodiment of the invention provides a fin base with a wedge angle that compresses an underlying wedge, thereby “wedging” the fin in the fin box. A further embodiment has a button on the fin that compresses a springy material as it passes over a fin box lip, thereby removably securing the fin in the fin box.
