Abstract: Aquatic curtain devices and methods for forming waterway channels and reducing waterway maintenance are disclosed. Each curtain device comprises an elongated float and an elongated flexible curtain depending from a first side of the elongated float. The curtain has a bottom end with a weight extending along the entire length of the elongated float. The float is configured to be sufficiently buoyant to support the curtain in an upward direction. Each curtain device is configured for the curtain to remain in a substantially taut state when in use and accommodate fluctuations in water levels, such that the elongated weight remains on the bottom of the waterway while the elongated float remains on the surface. Artificial channels are constructed by selecting the length of the elongated float to achieve the desired channel dimensions using two or more curtain devices positioned along a desired path in a waterway.

Abstract: An inflatable hot tub kit that includes a self-supporting tub structure that can be used on ground or used in a body of water. The kit includes a thermostat and hoses designed to connect to an external fresh water supply system. The tub structure comprises three inflatable ring sections that form the sidewalls designed to hold warm or hot water. The upper ring section is octagonal-shaped when viewed in plan view. In cross-section, the upper ring section is circular and relatively large so that when the tub structure is placed in a body of water, the water edge is approximately 8 to 10 inches below the top surface of the upper section. The middle ring section is flat in cross-section and vertically aligned under the center axis of the upper ring section. The middle ring section provides buoyancy and supports the upper ring section when used on the ground or extends into the body of water to provide buoyancy. Attached to the middle ring section is an inflatable lower ring section.

Abstract: A submersible fabric tub is floated in a swimming pool or other body of water, the tub having an upper floatation collar from which the flexible fabric structure of the tub is suspended. The tub has a pair of opposed bench seat portions with a deeper leg well located between them, and with enclosing end walls. A pair of access ports in an end wall connect by way of connecting hoses with an external heating or cooling water supply, by which the temperature of the water within the tub structure may be conditioned to a desired extent. The flexible floatation collar can be readily locally depressed, enabling users of the tub to readily enter or leave the tub for the surrounding body of water by swimming over the collar. The bench seat portions incorporate plastic reinforcing beams.
