ABSTRACT:
An adjustable fin system for a watercraft such as a surfboard, includes a fin having a base, a foot extending from the base, a fin box mountable within a hull of the watercraft and a manually operable detent mechanism for releasably holding the fin in a plurality of different positions relative to the fin box. The fin box defines a cavity for receiving the foot. The cavity has an opening on a first surface through which the foot is inserted. The opening and the base are relatively dimensioned so that when the foot is received within the cavity the base substantially covers the opening.
