The present disclosure provides an improved design for a multi-sectional truss spar hull platform having a truss and a spar hull. One or more sections can be transported to a designated location and off-loaded into water from an available transport vessel. The truss includes a skirt tank at the upper end of truss that can be coupled to the lower end of the hull. The skirt tank can provide buoyancy during float-off and mating operations to the hull. The skirt tank is designed to allow the portion above the water to be coupled to the hull in a first orientation, the truss with the skirt tank rotated with the hull in the water to a second orientation to expose the previously underwater portion, and then the previously underwater portion can be coupled together above the water. The integral skirt tank will be flooded after the spar hull is up-ended.

A slip style bobber comprising a hollow central housing constructed from a first mating half and second mating half. The hollow central housing includes a mounting member for the attachment of a pair of printed circuit boards having a replaceable power source, a switch, and a light source. A pair of tubes arranged coaxial are received within mounting member and extend from the interior of the housing to the exterior of the bobber. The bobber is water tight and constructed out of a translucent plastic to allow for illumination of the device during low light conditions. The bobber is multi colored and reversible.

A squirting toy is comprised of a cylindrical housing and a piston that slides within to force water into or out of the housing via a hole therein. The housing is encased within a shell creating a water impervious volume sufficient for the toy to float in water. The shell is soft, so that the gun is not a safety hazard when left floating in a swimming pool. The squirting toy can further include bellows that can provide safety benefits as well as other benefits.

A floating strainer is constructed having a rectangular frame. A cylindrical drum is attached to each corner of the rectangular frame. Below the rectangular frame, a box-strainer is fixed. The distance between the box-strainer and the rectangular frame is adjustable so that the level at which water is drawn can be raised or lowered. The bottom of the box-strainer includes hose connections. These are positioned so that the hoses connect at the bottom of the floating strainer and extend vertically down from the bottom. This configuration operates to distribute the weight of the hose and reduce stress and strain on the hose.

A vehicle is adapted to operate on land and in water having a depth of over four feet. The vehicle includes a chassis, one or more pontoons supported by the chassis, and a track system disposed on each of the one or more pontoons and adapted to provide propulsion to the vehicle. Each pontoon has a height of at least four feet, a width and a length adjacent to the land, wherein a ratio of the height to the width exceeds 1.4, and a volume configured to provide buoyancy and support the chassis weight.

A system is disclosed for providing emergency buoyancy to a vessel in response to a flooding condition in one or more vessel compartments cause by external explosion, collision or projectile damage. The system may comprise one or more flexible inflatable bags disposed on an upper inboard bulkhead of one or more vessel compartments. When a flooding condition is detected in a compartment due to breach of the ship's hull, an integral gas delivery system may provide a quantity of gas to the interior of the bag in that compartment, causing the bag to expand and push flooding water back out through the ship's hull. This displacement of water, and the buoyant force provided by the filled bag will enable the ship to maintain nominal floatation. The system may be configured to provide a controlled expansion of the bag(s) to enable personnel located in the compartment sufficient time to evacuate.

A floating fountain that includes of a tubular, hollow base assembly that can be connected to a pressurized source of fluid, a primary nozzle member located centrally to the base assembly, and a plurality of secondary nozzle members located on the base assembly. Each nozzle member is connected to the base assembly such that pressurized fluid may be communicated from the base assembly to the primary nozzle member and the secondary nozzle members in a manner that allows the pressurized fluid to be organized into separate streams of fluid, which extend from each respective nozzle member. A float body is affixed to a bottom side of the base assembly to provide buoyancy to the floating fountain device. Additionally, an infinitely variable valve is included between the pressurized source of fluid and the base assembly so that the pressure at which the pressurized fluid enters the base assembly and is provided to each nozzle member may be variably controlled.

A method and apparatus is provided to support a plurality of objects such as keys with an inflatable apparatus when the inflatable apparatus is exposed to a body of water. In one embodiment, an inflatable apparatus provides an attachment member such as a key ring to attach objects such as keys to the inflatable apparatus. The inflatable apparatus is capable of inflating from a compact shape to an expanded shape upon contact with water. In the expanded shape, the inflatable apparatus provides sufficient buoyancy to support the objects coupled therewith and float the objects to the surface of the water for retrieval by a user. In situations where the weight of the object exceeds a buoyancy limit, the inflatable apparatus can extend a marker buoy to assist in the retrieval of the objects. In other embodiments, the inflatable apparatus includes a wireless transmit a wireless location signal.
