Abstract: One or more variable angle fin box assemblies are sealed on the underside of a surfboard or the like that allows the angle of attack of the fin to be varied with the respect to the longitudinal axis of the surfboard, enabling the speed, stability and maneuvering characteristics of the surfboard to be adjusted or "tuned" by the rider in accordance with the rider's level of skill, different surf conditions and wave sizes. The novel fin box assembly has a longitudinal channel to receive the base end of a conventional surfboard fin, and in which a device is provided for securing the movable fin in the selected adjusted angular position.

Abstract: A sports cap is fabricated to provide maximum sun and wind protection to the face, ears, and neck of the wearer during use in land, and especially in water activities. These unique results are achieved by constructing the cap with a crown having front and rear brims. The rear brim may be made detachable from the crown, and used independently as a front visor or be attached to the rear portion of any other cap or hat. The brims are made from a mesh material with variable density and maintained in shape by a tensioned flexible rod secured along their periphery. The mesh material reduces resistance to wind and water, minimizing loss of the cap during very active use, and filters the passage of light. When the cap is applied to the head the tensioned rods enable the front brim to be flexed either to an upper position for an unobstructed field of vision, or flexed to the lower normal position for maximum sun and wind protection. The cap may contain a buoyant material to keep it afloat in water.
