The invention provides a solution to people who want to enjoy therapeutic exercises in water using body boards but do not yet have the necessary skills to maneuver themselves alone. This invention serves as a way of acquiring these skills through a body board anchored to a fixed position and leaving a reasonable amount of space for the user to freely move his/her body without interfering with the operation of the board.

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.

A powered watercraft system including a watercraft body having a propulsion system, a foot swimfin, a sensor configured to measure a value indicative of a manually-generated time-variable first propulsive force resulting from a leg motion to the foot swimfin to move the watercraft body, and a controller configured control the propulsion system to generate a second propulsive force for powering the watercraft body based on the value indicative of the first propulsive force, the generated second propulsive force being at least partially contemporary with the first propulsive force.

A motorized, steerable, electrically-operated personal watercraft that includes a hull with a bow, stern, top deck surface, underside surface, and a support and steering console. The deck is configured to allow a user to lie prone on the deck with the user's chest located on or proximate the console. There are left and right steering control devices located at the left and right of the console, respectively. The steering control devices are configured to be manipulated by the left and right hands of the user. Motive power and steering are both provided through an electrically-powered water jet, which may be but need not be located at the stern. The water jet is mounted to a fixture that is configured such that the outlet nozzle of the jet can be turned left and right, in order to steer the craft to the left and right. Jet nozzle steering is accomplished by manipulation of the left and right steering controls. User-operable kill switches also located at the left and right of the console must be operated in order to operate the jet.

One embodiment of this invention provides a body sure article providing a planing device having an inclined shape behind a leading edge, forming a planking effect when in use and an overall size and shape that allows a specific position relative to a user's arms and/or elbows. A material is used having a density sufficient to be slightly buoyant relative to water, but is easily submerged under waves momentarily without substantial opposition force to a user duck diving.

An exhaust system for a combustion engine vehicle includes an exhaust pipe extending between an exhaust inlet disposed opposite an exhaust outlet. The exhaust inlet and exhaust outlet are in fluidic communication with one another. The exhaust inlet is configured to receive an exhaust gas produced by an internal combustion engine of the combustion engine vehicle. A second pipe has an air inlet extending from and connected to the exhaust pipe. The second pipe is configured to be in fluidic communication with the exhaust outlet. The air inlet is configured to receive an outside flow of air. The exhaust gas from the combustion engine vehicle and the outside flow of air captured by the air inlet when the combustion engine vehicle is moving forward are configured to be combined and to cooperatively exit out the exhaust outlet.

A surfboard baffle arrangement system may be provided utilizing a watercraft body having a first side surface and a second side surface. The surfboard baffle arrangement system may further utilize an array of baffle structures disposed into the watercraft body and through the first side surface. Each baffle structure within the array of baffle structures may have a baffle retainer and a baffle panel such that the baffle panel and the baffle retainer may be operably coupled to one another. Further, the baffle panel may have one degree of freedom of rotation relative the baffle retainer such that the one degree of freedom of rotation utilizes rotation of the baffle panel between an open configuration and a closed configuration.
