A motorized water sports equipment rack and method for motorized swiveling of a water sports equipment rack attached to a boat are disclosed. The motorized water sports equipment rack includes a mounting bracket for securing the mounting bracket to the boat and a water sports rack mounting bolt connected to the mounting bracket. A swivel bracket is connected to the water sports rack mounting bolt. A water sports equipment rack mount is connected to the swivel bracket. The water sports equipment rack mount supports a water sports equipment rack adapted for holding various types of water sporting equipment. A sealed actuator housing is connected to the swivel bracket and houses an actuator, such as an electric, pneumatic or hydraulic actuator. The actuator is configured to drive the swivel bracket to rotate the water sports equipment rack.

The invention relates to a water sport device having a sitting or standing surface (2) for a person practicing water sports, a jet drive (8) and a pivotable nozzle (13), wherein a fin (23) is disposed at the nozzle (13) and is arranged in a fixed position relative to said nozzle.

Hydrofoil assemblies that can be attached to a board used for watersports are disclosed herein. A hydrofoil assembly may include, for example, a mast a coupleable to a fuselage at a lower portion of the mast and coupleable to a board at an upper portion of the mast, and front and rear wings coupleable to the fuselage. A hydrofoil mast may include, for example, first and second composite sections bonded together to form a hollow load-bearing mast structure. Leading and trailing elements made of a material that is softer than the composite mast structure may be adhered to the mast structure to complete a hydrodynamic profile of the mast.

Embodiments of water activity board 10 that may be configured with several components 210A-H to form a WABS 200, where the components 210A-H may be securely and removably coupled to the board 10 via one or more rail modules 100A-I. Other embodiments may be described and claimed.

A motorized hydrofoil apparatus may include a sailboard having a top surface and a bottom surface; a first hydrofoil assembly having a first hydrofoil and a first support unit; a second hydrofoil assembly having a second hydrofoil and a second support unit; and a propulsion system. The hydrofoil apparatus may also include one or more sensing units disposed on predetermined locations on the first support unit to operatively communicate to a plurality of actuating units on the first hydrofoil assembly and second hydrofoil assembly to automatically generate corrective responses to various destabilizing hydrodynamic effects to stabilize the hydrofoil apparatus.

A watersport board includes a board body, two female fasteners, a baseplate, a fin adapter, a fin and two male fasteners. The board body defines a receptacle. The female fasteners are embedded in the board body. Each female fastener has a receiving hole. The baseplate is attached underneath the board body. The baseplate has a first bore and two second bores. The fin adapter has an adapter body and an extension laterally extending from the adapter body. The adapter body passes through the first bore of the baseplate and is engaged in the receptacle of the board body, and the adapter body has a cavity. The fin has a base portion received in the cavity of the adapter body. Each male fastener has one end connected to the extension of the fin adapter, and the other end passing through the second bore of the baseplate and being engaged in the receiving hole of the female fastener.

A fin mounting assembly having a fin box and a cover plate. The fin mounting assembly has a fin box with an upper end that is substantially closed and a lower end that is open with an outer edge. An elongated recess is disposed substantially central along a first axis of the fin box that is adapted to receive and secure a base of a fin. The upper end of the fin box has a flange with an outer border. The flange has a gradually increasing wall height curvature along the first axis, beginning adjacent to the outer edge of the flange and a greatest wall height curvature at a flange central portion. The flange also has a slot cover wall that extends up and away from the flange along the first axis and positioned over the elongated recess. The slot cover wall has an increasing width thickness beginning at the outer edge of the flange that increases in width and has a largest width at a slot cover central portion. A cover plate has an outer border and is adapted to be attached to the outer edge of the fin box.

A single support stake surfboard support for elevating surfboards above a sandy beach. An elongated, hollow support stake, typically having a diagonal cut at its distal end to facilitate pressing the support stake into sand or other terrain. A T-support arm is removably, frictionally attached to a proximal end of the hollow support stake. In a first embodiment, cylindrical polymer cushions are disposed along the T-support arm. In the first embodiment, one or more surfboards may be laid flat across the pair of supports. In a second embodiment, at least two upwardly projecting members are attached to the distal and proximal ends of the T-support arm. Each of the upwardly projecting members may also have one or more cylindrical polymer cushions thereupon. In the second embodiment, up to four surfboards may be accommodated on edge between the upwardly projecting members.

A device for carrying a surfboard, similar sporting equipment or other objects. One embodiment is comprised of webbing material with fixed loop 24 having a buckle 22 that slides along the fixed loop 24 and a strap element 20 that in combination with the buckle 22 creates a secondary adjustable loop. The secondary adjustable loop is used to hold a surfboard or other object securely in place and the fixed loop 24 supports the surfboard from one of the user's shoulder allowing hands free operation. When not utilized as a carrier the device can be worn, such as a belt. The user keeps the fixed loop 24 compressed together, wraps the carrier around his/her waist, through the buckle 22 and then attaches it back onto itself.

A fin box is provided for detachably attaching a fin to a surfboard. The surfboard has a nose and a tail at opposite ends. The fin has a groove base with one or more pins. The fin box includes one or more inner walls. The inner walls have (i) a hollow base with a width that is at least as great as a width of the groove base and a length that is at least as great as a length of the groove base, (ii) one or more recess parts disposed at locations that correspond to the locations of the pins of the fin, the recess parts extending in a direction that is substantially perpendicular to a length of the fin box, and (iii) one or more ditch parts that extend from the recess parts, the ditch parts extending in a direction that is substantially parallel to the length of the fin box and toward the tail of the surfboard. The recess parts and ditch parts are configured to allow the fin to be inserted into the fin box by (i) pressing the fin downward into the fin box until a bottom of the groove base is adjacent to the hollow base, and (ii) sliding the fin toward the tail of the surfboard, without any opposite motion toward the nose of the surfboard. The ditch parts are configured to, when the fin is attached to the fin box, hold the pins of the fin in the fin box.
