摘要： A system for propelling a paddleboard or surfboard along the surface of a body of water, comprising a controller motor coupled to a propeller, a rechargeable battery, a controller which may be wearable on the wrist of a user, and a housing structure that is adapted to be attached to the fin box of a paddleboard without the need to remove the fin. The apparatus presents a low-drag profile, has a long battery life for extended range, and is able to be controlled so that user may operate the paddleboard at any desired speed, and in a forward or rearward direction, or in a controllable direction of thrust. The housing structure is adaptable to various fin box T-bolt separation distances.

摘要： A stern rudder fixing structure for fixedly connecting a stern rudder body to a stern rudder base is disclosed. The stern rudder fixing structure comprises a T-shaped bolt, a nut and a rotary rod, wherein the stern rudder body is detachably connected to the stern rudder base. The stern rudder comprises a stern rudder body, a stern rudder base and a fixing structure. The stern rudder and a paddle board provided by the disclosure are matched with a first insertion hole and a second insertion hole of the stern rudder base through the fixing structure, so that the stern rudder body and the stern rudder base are quickly assembled and dissembled in a time-saving and error-saving mode.

摘要： A fin for use on a surfboard, the fin comprising: a leading edge, a trailing edge, and a base, the base comprising at least one mount for mounting the fin onto a surfboard; a first and a second outer fin surface which meet along the leading edge and the trailing edge and abut the base; and a first ridge protruding laterally from the first outer fin surface, and/or a second ridge protruding laterally from the second outer fin surface; wherein the shape and configuration of the fin creates an area of lower water pressure around and in front of the fin, as well as disrupting and/or reducing the size of trailing vortices, resulting in additional forward thrust for the board on which the fin is mounted.

摘要： The invention relates to a hydrofoil for a watercraft including a fuselage and two wings arranged on either side of the fuselage and designed to provide hydrodynamic lift to the hydrofoil when it is moving through the water. According to the invention, the two wings are rotatable relative to the fuselage between a deployed position when the hydrofoil is stationary, and a retracted position towards a rear part of the fuselage by the water pressure exerted on the wings when the hydrofoil is moving through the water.

摘要： A personal watercraft includes a floatation member, a thrust assembly, a steering assembly, and a braking assembly. The assemblies may be actuated either mechanically or electrically. The thrust assembly is human powered, solar powered, or electric powered. The thrust, steering, and braking assemblies can be added after-market to an existing stand-up paddle board (SUP), or built into one or a plurality of SUPs during initial manufacturing. When the thrust assembly is human powered, it is leg or arm powered. When the thrust assembly is leg powered, the legs can move backward and forward in a sliding motion, up and down in a stomping fashion, or move in a loop trajectory. When the thrust assembly is arm powered, the arms can move forward/backward together or separately. The thrust assembly includes one or a plurality of paddles or flippers that are positioned to the side or under the SUP.

摘要： A surfboard includes a first layer and a second layer. The first layer is defined by epoxy impregnated fiber reinforcement fabric configured to cover a rocker and rails and wherein the first layer extends onto a deck at a middle portion of the surfboard and tapers toward a tip and tail so that the first layer does not extend onto the deck at the tip and the tail. The second layer is defined by epoxy impregnated fiber reinforcement fabric configured to cover the deck and wherein the second layer extends to cover the rails at the middle portion of the surfboard and tapers toward the tip and tail so that the second layer covers less than half of the rails at the tip and the tail.

摘要： Watersport board fins with fin retention systems and associated watersport boards and methods. A fin includes a hydrodynamic blade and a fin base extending from the hydrodynamic blade. The hydrodynamic blade defines a fin plane and includes a leading edge, a trailing edge, and a foil surface. The fin further includes a fin retention system with a selective retention system that includes a retainer and an actuator coupled to the retainer via a pivot shaft. The actuator forms a portion of the hydrodynamic blade when the selective retention system is in a locked configuration and is configured to rotate away from the fin plane when the selective retention system transitions from the locked configuration to an unlocked configuration. The retainer is configured to rotate away from the fin plane when the selective retention system transitions from the unlocked configuration to the locked configuration.

摘要： A hydrofoil watercraft, in particular, a hydrofoil board is described herein. The hydrofoil board may comprise one or more of a body, a hydrofoil assembly, and/or other components. The body may have one or more of a deck surface configured to support a rider, a bottom surface opposite the deck surface, and/or other surfaces and/or features. The body may comprise a fore portion having a planing surface forming part of the bottom surface. The body may have an aft portion having an aft bottom surface forming part of the bottom surface. The fore portion may be toward a front end of the board. The aft portion may be toward a rear end of the board. An aft cross-sectional thickness between the deck surface and the aft bottom surface may be less than a fore cross-sectional thickness between the deck surface and the planing surface.
