This invention is related to an apparatus and a method for aquatic propulsion by use of a swimming aid comprising an anchoring article and handles that are compressed and retracted in a scissor-like fashion by a User. This inward and outward motion translates by way of a pivot point to the other end of the handle, causing another set of arms operably connected to the anchoring article by way of two sets of straps, to pivot in a manner perpendicular to the motion of the handles, thus causing two vertical fins to move laterally through the water, displacing water, and propelling the user in a forward direction. In a preferred embodiment of the present invention, foldable fin arms are attached to the second set of arms that is manipulated by the straps.

A jewelry display has a ferromagnetic planar substrate having a front surface opposite a back surface. A wall attachment mechanism is attached to the back surface of the ferromagnetic planar substrate. The wall attachment mechanism is configured to attach the ferromagnetic planar substrate to a substantially vertical surface, such a wall. A plurality of jewelry fixtures are configured to be removably attached to the front surface of the ferromagnetic planar substrate. Each jewelry fixture has at least one permanent magnet and a jewelry holding structure. The at least one permanent magnet of each jewelry fixture is magnetically attracted to the ferromagnetic planar substrate. At least one of the plurality of jewelry fixtures is a ring holding structure, a bracelet holding structure, an earring holding structure, a necklace holding structure, a watch holding structure, a bowl structure or a shelf structure.

Examples are disclosed that relate to watercraft with retractable drive mechanisms. One example provides a watercraft including a hull having a receiving compartment, and also having a deck. The watercraft also includes a drive unit extending through the deck and the hull of the watercraft and being configured to receive rotational input. The drive unit includes a driveshaft and propeller moveable between an extended position in which the propeller is positioned underneath the hull and a retracted position in which the propeller is positioned at least partially within the receiving compartment.

A watercraft includes at least one floating member, a central frame supported thereon, first and second foot platforms, and first and second handlebars. The first and second handlebars define elongated configurations and include grasping end portions, intermediate portions pivotably coupled to the central frame, and base end portions pivotably coupled to first end portions of the respective first and second foot platforms. A propulsion system includes an axle assembly, first and second rotating arms, and first and second oars. The rotating arms are fixed relative to one another, pivotably coupled about the axle assembly at first ends, and pivotably coupled to second end portions of the foot platforms at second ends. The oars are engaged with and extend from the foot platforms. The propulsion system cycles the oars approximately 180 degrees out of phase to propel the watercraft while maintaining substantially perpendicular orientation of the oars.

A device that propels a swimmer to move above or below the water surface allowing it to ascend, dive or turns on its axis is disclosed. It allows great capability of movement in water, due to its control fins. This allows it to be used as a sport, recreational, water use item, such as diving or to equip lifeguards or water rescue teams that need to move at higher speeds.
