Abstract: A system and method for circulating water in a swim spa. A recessed chamber formed in the shell of the spa defines a space to hold at least a portion of a first, upper horizontal water propulsion device and at least a portion of a second, lower vertical water propulsion device. The first, upper horizontal flow of water is combined with the second, lower vertical flow of water to create a third, horizontal flow of water. The resulting turbulence is lower, creating a more laminar flow and better user swimming experience. Jet bodies with side intakes may maximize capacity of the water propulsion devices.

Abstract: A reinforcing system for a vessel that can contain water. The system includes a shell for containing water, the shell having one or more jets extending therethrough from an inside of the shell to an outside of the shell, and a structural support layer on an underside of the shell. The structural support layer can include: an inner layer of rigidizer applied to the underside of the shell, a central low density core, and an outer layer of rigidizer applied to the central low-density core. The structural support layer can extend from a bottom side of the underside of the shell, across at least one sidewall of the underside of the shell, and form at least one rib along the sidewall of the underside of the shell.

Abstract: A system and method for providing a hammock for a user to rest thereon in the water of the spa. The hammock may include a proximal end with head support portion and one or more attachment means for connection to an anchor on the spa shell, and a distal end with one or more attachment means for connection to an anchor on the spa shell. One or more lateral coupling members may couple the hammock to the lateral sides of the spa, and one or more longitudinal coupling members may couple the hammock to a front side and/or back side of the spa. The longitudinal and lateral coupling members may support the hammock in the water to give the user a unique flotation experience.

Abstract: A system and method for providing an exercise bar for a user to use for rowing or other exercises in the water of the spa or adjacent to the spa. The exercise bar may comprise a central hub, and two sides, each with a first inner tube attached to opposing side of the central hub and a an outer tube in telescoping connection with the inner tube, and a handgrip in connection with the first outer tube. A connector may be mounted to the central hub, the connector to enable the exercise bar to be connected to one or more resistance cables. The exercise bar may be adjustable from a first, shorter length for use with exercises in which a user's hands are positioned closer together and a second, longer length for use with exercises in which a user's hands are positioned father apart.

Abstract: A system and method for reinforcing a spa shell includes a structural support layer on an underside of the spa shell. The structural support layer may include an inner layer of rigidizer, a central foam layer, and an outer layer of rigidizer. The structural support layer may extend from a bottom side of the underside of the spa shell, across at least one sidewall of the underside of the spa shell to a lip of the spa shell, the structural support layer forming at least one rib along the sidewall of the underside of the spa shell.

Abstract: A system for supporting a spa shell may include a structural support paddle. The paddle may include a base portion and a paddle portion, connected to each other through an articulating joint such as a ball-and-socket. The top side of the paddle portion may include one or more pieces of cushioning material, such as EPF foam. The structural paddle assembly may be placed between the base of the spa and the spa shell. Typically, 5 or more paddle assemblies are placed in a spa for support, such as in the lowest areas of the spa shell and/or concavities, or convexities, of the spa shell. Compared to typical large blocks of foam used to support a spa shell from beneath, the structural support paddles provided increased room below the spa shell for ease of maintenance and installation, and more directly controlled support.

Abstract: A water jet suitable for use in a water recreational apparatus has (a) a body defining a body interior passageway between a body inlet opening and a body outlet opening, the body having (a) a light well with an open external end and a closed transparent internal end, and (b) an insert disposed largely within the body, the insert defining an insert interior passageway between an insert inlet opening and an insert outlet opening, the insert defining a flange cover at the proximal end of the insert. The insert is moveable within the body between a water open position and a water closed position. The insert is also moveable within the body between a light on position and a light off position.
