An oscillating reversible motor providing a novel means of converting oscillating motion into selectable clockwise or counterclockwise rotary motion. More particularly, the invention presents a novel approach to a foot or hand pedal driven apparatus with which a traditional rotary water propeller or other output device may be employed in both forward and reverse directions of relative motion.

A jewelry display includes a ferromagnetic planar substrate and a bracket configured to be attached to a wall. The bracket has at least one wall engagement surface disposed along an inner surface and at least one ferromagnetic planar substrate engagement surface disposed along an outer surface. An adhesive backed non-slip covering adhesively attaches to the substrate engagement surface. At least one bracket magnet is disposed on the inner surface of the bracket. A plurality of jewelry fixtures are configured to be 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, where the at least one permanent fixture magnet of each jewelry fixture is magnetically attracted to the ferromagnetic planar substrate.

In an oscillating fin propulsion apparatus adapted for use by a disabled diver, a propulsion force may be produced by a fin adapted to sweep back and forth in a generally transverse direction relative to the traveling direction of the diver. The fin may be mounted on a scuba tank operatively connected to drive members that may be reciprocated by the diver. The oscillating fin may provide a propulsive force propelling the diver forward during both oscillating directions of the fin.

A tri-hull fishing kayak includes a platform, an elevated seat, a foot operated paddle, and a triple hull including two side pontoons and one forward central pontoon having a front portion and a rear portion. The front portion, extending centrally from the platform, provides enhanced longitudinal stability. The two side pontoons are of a width and separation to provide enhanced lateral stability. The tri-hull fishing kayak reduces the need to frequently re-position the kayak when there is wind and/or current, thereby minimizing interruptions to fishing. The elevated seat is ergonomic for long-term sitting, and is high enough above the water to facilitate effective pitching and casting underhand, and to permit a steeper viewing angle into the water, thereby making sight fishing easier. The foot-operated paddle can be used to precisely steer the kayak, and therefore frees up the user's hands for fishing. Further, the platform enables fishing while standing.

An elliptical powered watercraft includes a buoyant platform, a paddle wheel, pedals operatively connected to the paddle wheel, and a skeg, a fin, or a rudder operatively connected to a steering device, such as handlebars or a steering wheel. An operator propels the elliptical powered watercraft by balancing on the buoyant platform, generating rotational movement with the pedals to deliver power to the paddle wheel, and steering the elliptical powered watercraft by turning the skeg, the fin, or the rudder with the handlebars or the steering wheel.

There is disclosed a watercraft paddle apparatus operable by a user's legs and feet. In an embodiment, the watercraft paddle apparatus comprises a pair of rails positioned side-by-side and mountable to a watercraft, each rail configured to slidably receive a pedal mechanism adapted to slide back and forth along each rail. Each pedal mechanism includes a downwardly extendable paddle adapted to engage a water surface on which the watercraft is floating during a backward stride and to lift from the water surface on a forward stride, whereby a user can operate the pedal mechanism in each rail using an alternating walking or skiing motion. In an embodiment, each pedal mechanism is supported laterally by a front axle with a pair of wheels on either end of the front axle engaging the parallel rails. In another embodiment, each pedal mechanism is attached.
