A jewelry display includes a ferromagnetic planar substrate and a bracket attached to a wall. The bracket has a wall engagement surface along an inner surface and a ferromagnetic planar substrate engagement surface along an outer surface. A non-slip covering attached to the ferromagnetic planar substrate engagement surface abuts the back surface of the ferromagnetic planar substrate. At least one bracket magnet is attached to the bracket. The back surface of the ferromagnetic planar substrate is configured to removably attach to the bracket due to the magnetic force of the at least one bracket magnet attracting the ferromagnetic planar substrate and a frictional force between the non-slip covering and the back surface of the ferromagnetic planar substrate. A plurality of jewelry fixtures are removably attached to the front surface of the ferromagnetic planar substrate, each jewelry fixture having at least one permanent fixture magnet and a jewelry holding structure.

A dual drive system for providing motive power to a watercraft has a frame configured for connecting to the watercraft and a drive assembly connected to the frame. The drive assembly has a manual drive mechanism configured for receiving mechanical input from a user, a motor drive mechanism configured for receiving mechanical input from a motor, a driveshaft having a first end in selective engagement with one of the manual drive mechanism and the motor drive mechanism and a second end in engagement with a propeller, and a drive selector for selectively engaging the manual drive mechanism or the motor drive mechanism with the driveshaft based on a position of the drive selector between first and second positions. In the first position, the drive selector engages the manual drive mechanism with a driveshaft. In the second position, the drive selector engages the motor drive mechanism with the driveshaft.

A swimming enhancement device has a frame and a push bar pivotably coupled to the rear portion of the frame. A left end is rotatably coupled to the left portion of the push bar and a left foot pad is pivotably coupled to the left end. A right end is rotatably coupled to the right portion of the push bar and a right foot pad is pivotably coupled to the right end. A propulsion fin is attached to the push bar or to a tail bar distal end of the push bar. A receiver is movably coupled to the front portion of the frame. A body coupling device is attached to or formed as part of the receiver. The body coupling device is configured to removably attach to a portion of a user's body or be held by the user.

A paddle board has two tracks integrally associated therewith for the further attachment of a slide within each track thereon. Thus, to effect motion of the slide associated with the track the Supski Paddle System has two actuation drives that are rotationally associated with the aforementioned slides one to each slide respectively. Upon user actuation of the drive using a pole associated with the drive the slide is directed to move longitudinally upon a track or to insert a paddle into and out of the water.

A stand-alone modular removable rudder system for watercraft having a rudder comprising a steering handle coupled to a quick release mechanism adapted to releasably secure said steering handle to said watercraft in proximity to the operator, said system further comprising, a rudder mount adapted to be coupled to the rear of the watercraft by a quick release mechanism adapted to releasably secure said rudder mount to said watercraft, said rudder being carried by a rudder support pivotal about said rudder mount and cables operatively connecting said steering handle to said rudder mount whereby the steering handle can be operated to steer the rudder.

An apparatus for adjusting a human propelled watercraft having a pair of flexible fins extending into the water. The invention allows the user to easily adjust the propulsion device to match the user's leg length. The invention consists of a push button mechanism that converts a vertical motion into a horizontal motion allowing a locking pin to retract and the propulsion device to be adjusted. Once an adjustment position is selected, the user releases the button and a spring reverses the motion of the pin, locking the mechanism into position.

In the first position, the drive selector engages the manual drive mechanism with a driveshaft. In the second position, the drive selector engages the motor drive mechanism with the driveshaft.

A human propelled watercraft having a pair of flexible fins extending into the water each adapted to oscillate through an arcuate path in a generally transverse direction with respect to the central longitudinal dimension of said watercraft. Pedals are provided for applying input force whereby as input force is applied, the flexible fins can twist to form an angle of attack for providing forward thrust with respect to the longitudinal dimension of the watercraft while moving in both directions along the arcuate path. The user can pull a lever and cause the fins to rotate 180 and produce thrust in the reverse direction. The fins are able to pivot and swing aft to avoid damage if there is a collision with a submerged object. The fins are more efficient, durable, and adjustable. Simple plastic roller bearings have been adapted to reduce mechanical friction without the need for oil seals.
