Provided are stand up paddleboards (SUPs) and methods for exercising using a stand up paddleboard (SUP). The described SUPs optionally expand the fitness experience of a paddleboard to other fitness activities, including Yoga, Pilates, strength training, Boot Camp, and personal training tailored to the unique needs of the participant.

A user propelled water board apparatus (2) is described and comprises a hull, portion (4) defining a longitudinal axis x-x. The hull portion (4) is buoyant, to enable a user (6) to rest on hull portion (4) and be supported on the surface of a body of water (8). First and second lateral fin members (10) and (12) are pivotably mountable to the hull portion (4) in a position to project into the body of water in use. The first and second lateral fin members (10) and (12) are mounted in use on opposite sides of the hull portion 4 and are pivotable towards and away from the hull portion in the direction of arrow A. A user (6) rocking the hull portion in water about the longitudinal axis x-x causes the first and second lateral fin members (10) and (12) to pivot outwardly from the hull portion and drive the hull portion through the body of water in use.

An adapter system for attachment to a surfboard leash plug receive bar. The adapter system is able to be secured to and removed from a surfboard without any damage or alteration done to the surfboard. The adapter attaches to the surfboard leash plug and provides a surfboard tail mount for devices, including but not limited to a camera.

The swivel lock quick release device is adapted to selectively attach a user to a sports equipment. The sports equipment may be watersports equipment, such as a surfboard, a kite surfing apparatus, a stand-up paddle board, sailing equipment, a wake board, etc., or land sports equipment, such as fishing, camping, climbing, animal collars or leashes, tactical rifle apparatus, and hunting equipment. The swivel lock quick release device can have a pull release and a protrusion, the pull release and the protrusion being adapted to be selectively engaged in a locked position is provided. A slide handle, a portion of the pull release, is adapted to be selectively moved in a coaxial direction by the user to disengage the pull release and the protrusion. The pull release can also be adapted to rotate or swivel around the protrusion.

The present invention provides for a novel floatation device useful for use by a snorkeler.

The present disclosure is directed to a personal watercraft, such as a standup paddleboard, provided with a viewing window that allows the user to view the underwater environment. The viewing window may be watertight and constructed from at least two durable, transparent panels. The area between panels may be sealed from air and water infiltration. A user may add waterproof lights to the bottom of the standup paddleboard in order to allow viewing of the underwater marine environment at night.

A surfboard leash apparatus is disclosed. The surf leash apparatus includes a cuff for attaching to a limb of a surfer, the cuff having an inner surface, the inner surface of the cuff having a pattern of compressible grips disposed thereon. The surf leash further includes an attachment mechanism for attaching to a surfboard, and a leash cord connected between the cuff and the attachment mechanism. The leash cord includes an elastic fiber rope core having a predetermined amount of stretch, and an extruded thermoplastic urethane cord surrounding the elastic fiber rope core. The extruded thermoplastic urethane cord has an elasticity corresponding to the predetermined amount of stretch of the elastic fiber rope.

An adapter for mounting a mounting structure on a flush mount receptacle base. The adapter includes a mounting base and an anchor. The mounting base includes a rotatable drive member with an interface surface configured and arranged for placement on a mounting surface, the rotatable member also has a bore extending thereinto and aligned with the interface surface, and the bore is at least partially threaded. The anchor extends into the bore of the drive member, the anchor has a shaft with first and second end portions and defining a center axis, the first end portion of the shaft is threaded to mate with the threaded bore of the drive member and configured and arranged to rotate relative to the drive member, the anchor also has at least one hook coupled to the second end portion of the shaft and laterally offset from the center axis of the shaft.
