Abstract
A water craft having an adjustable fin assembly. The fin includes a base having a circular cross-section for rotating within a circular recess formed in a fin box attached to a water board. A means is provided for securing the fin at a predetermined angle of attack. The fin may be secured by a set screw or pin passing through the fin box and making contact with the base. The pin may pass through a hole in the base to provide vertical and rotational support for the fin. The pin may be moved between an engaged position and an unengaged position by the rotation of a gear interfacing with teeth formed on the pin. The fin base and fin box may include mating projections and slots for securing the angular position of the fin and an associated pin for retaining the fin within the fin box.
