ABSTRACT:
A water sports board for use in supporting a person riding along on the top surface of the water. The elongated buoyant board has an elongated slot in its bottom surface for each of its fins. The fins are removably received in the elongated slots when the fins are raised up into the interior of the board. A mechanical structure is utilized for reciprocally moving the fins between an upper position inside the slot and a lower position in which a predetermined portion of the fin extends below the bottom surface of the board. A hydraulic system is used for actuating the mechanical means. It utilizes a resilient compressible bladder that is squeezed or released to move the pin between its upper and lower positions. The water sports board may take the form of a bodyboard, surfboard, kneeboard or wakeboard.
