A therapeutic flotation device and a therapeutic method of use thereof is disclosed. The device includes a plurality of buoyant float elements and a member (an elongated web strap) that couples each of the buoyant float elements such that the buoyant float elements are serially aligned along the member. A first end of the member is secured to a second end of the member. A mating mechanism, such as a buckle, secures the first end of the member to the second end of the member, or the two ends of the member may be permanently secured to each other using an adhesive or by being sewn together. Each of the buoyant float elements has a center aperture aligned along the center of a cross-section thereof. The member is preferably coupled to each of the buoyant float elements by being sequentially passed through the center apertures of each buoyant float element.

Disclosed are systems, devices, and methods for swimming using a swimming apparatus that includes an exterior shell, optionally including a top half and bottom half and an opening to accommodate a propulsion system.

Wakeboat hull control systems are provided that can include a first accelerometer operatively associated with the hull of the wakeboat to measure the acceleration of the hull along a first axis; a second accelerometer operatively associated with the hull of the wakeboat to measure the acceleration of the hull along a second axis, the first axis being non-parallel to the second axis; and processing circuitry calculating the rotation of the hull of the wakeboat about a third axis based on the acquired measurements. Wakeboat hull control methods are provided that can include using the processing circuitry to calculate the rotation of the hull of the wakeboat about a third axis based on the acquired measurements.

Many different types of systems are utilized and tasks are performed in a marine environment. The present invention provides various configurations of castable devices that can be operated and/or controlled for such systems or tasks. One or more castable devices can be integrated with a transducer assembly, such as a phased array, that emits sonar beams and receives sonar returns from the underwater environment. Processing circuitry may receive the sonar returns, process the sonar returns, generate an image, and transmit the image to a display.

A watercraft with improved safety and stability is provided. The watercraft includes a shell defining a plurality of raceways for receiving water during certain maneuvers of the watercraft, thereby excerpting force upon the watercraft in a first direction. The shell is configured so as to prevent or otherwise inhibit the water from excerpting an opposed second force upon the watercraft. An intermediate panel of the shell provides increased flexibility, thereby serving as a shock absorber for the watercraft.

A swimming pool Smart Boat for pool maintenance and water safety is described. The Smart Boat includes chlorine and pH sensors for monitoring water quality and is capable of releasing chemicals into the pool water based on monitoring. A screen panel is configured to trap debris in the pool. Additionally, the Smart Boat provides for water safety by monitoring water disturbances which indicate a swimmer has entered the pool and sending an alert based on the detection of a disturbance. A remote control unit provides alerts and controls navigation, the release of chemicals and the screen panel position.

A floating water mat reel that has a plurality of plates mounted to an axle. A floating water mat is selectively connected to the plates. A crank, connected to the axle is used to rotate the plates so that the mat wraps around the plate.

A floatation mattress assembly for sleeping upon or floating in a body of water includes a mat that is comprised of a resiliently compressible material for sleeping upon. The mat is comprised of a buoyant material to float on a body of water. The mat is structured to have the ornamental appearance of a flip flop article of footwear. A first tube is pivotally coupled to the mat, and the first tube is positionable in a deployed position or a stored position. A second tube is coupled to the first tube and slidably extends through the mat. Thus, the first and second tubes have the ornamental appearance of foot straps on the flip flop article of footwear. A net is removably attached to each of the first and second tubes. The net forms a hemispherical dome over the mat when the first tube is positioned in the deployed position.
