A vehicle (20) consisting of a frame (22) with a pair of paddles (72) extending longitudinally and rotatably supported by the frame (22) in pendulum fashion for swinging movement between an extended position engaging the surface and a retracted position moved vertically out of engagement with the surface. A pair of foot platforms (74) are operatively connected to the paddles (72). A pair of depressors (84) interconnects the foot platforms (74) and the paddles (72) to rotate the paddles (72) between the extended position and the retracted position. The paddles (72) include a propulsion bar (86) and an oar (88) connected by a lost-motion connection to slide relative to one another between the extended position and the retracted position. The oars (88) have a fin-shape to propel the vehicle (20) over water and include a striker (90) to propel the vehicle (20) over land. The vehicle (20) allows movement over a surface of water and land using an elliptical motion similar to the natural motion of walking.

A human propelled watercraft having a pair of flexible fins supported by a mast 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. Each of the fins preferably is composed of a layer of stiff and durable material that is wrapped around the mast. The two layers of material touch at the trailing edge and they are free to slide relative to each other. Preferably, each of the fins is provided with adjustable tensioning at the tip of the mast.

A watercraft having propulsion means extending below the water line comprising a pair of flexible fins each adapted to oscillate through an arcuate path in a generally transverse direction across the central longitudinal dimension of the watercraft. As input force is applied, the fins twist to form an angle of attack for providing forward thrust while moving in both directions along the arcurate path. Each of the fine have a generally squared off top and preferably an outer area of harder rubber than the inner area. Each of the fins can be adjusted at the trailing edge to provide adjustable tensioning of the trailing edge.

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 watercraft includes a hull, an opening extending vertically through the hull, and a support assembly configured to mount a propulsion mechanism to the watercraft. The hull at least partially defines the opening. The support assembly includes a rightward support device attached to the hull, positioned between a forward portion of the opening and a rearward portion of the opening, and at least partially defining a right lateral portion of the opening. The support assembly further includes a leftward support device attached to the hull, positioned between the forward portion of the opening and the rearward portion of the opening, and at least partially defining a left lateral portion of the opening.
