A simple shelter for flood evacuation that is lightweight and easy to carry, compact in storage, and low in cost includes a substantially cylindrical floating body formed by a plurality of floats stacked in a vertical direction, where vertically adjacent floats are connected to each other; and two partition plates provided on the inner peripheral side of the uppermost and lowermost floats, respectively, of the plurality of floats, the inner peripheral surface of the floating body and the two partition plates form a closed accommodation space for accommodating evacuees by preventing water from entering from the outside, and a door for evacuees to enter and exit the accommodation space is provided in the two partition plates.

A portable marine camping apparatus that is configured to provide a camping and recreational platform that can navigate waterways wherein the present invention is inflatable so as to facilitate easy transport thereof. The present invention includes a deck assembly that is superposed a hull portion wherein the deck assembly is planar in manner and includes rigid high pressure air chambers. Integrally formed with the deck assembly is a tent module wherein the tent module is manufactured from inflatable components and is deployed during inflation of the deck assembly. A boat unit is operably coupled to the rear of the deck assembly and is configured to provide propulsion of the portable marine camping apparatus 100. A fire module is formed with the deck assembly and is manufactured from steel grate panels. The fire assembly further includes a receptacle for receiving combustible materials.

An inflatable stand up paddleboard, combined with a thermally insulated compartment is disclosed herein. The compartment may be used for storage of food, drink, personal effects, and other items that may require storage in a temperature stabilized medium. As constructed, the compartment and storage of items therein does not diminish the functionality or versatility of the inflatable paddleboard.

Semi-rigid boat sailing on a foil (1) comprising a foil well for raising the foils on the boat in the high position, characterized in that the foils are foils with shortened arms positioned laterally at the level of the driver's seat (12), the foil well fits into the driver's seat which is a trunk with two side doors (41, 42) which open onto the foil position stop adjustments (43, 44), inside the seat trunk there is a shock absorber (44) to cushion navigation shocks.

The present invention provides a nose cone system that comprises an inflatable body, a plurality of retainer ribs, a retainer trough positioned below the inflatable body, a plurality of winches attached along the outer surface of the retainer trough, and a plurality of winch straps with which to pull in the inflatable body as it is deflated while holding it in place, in coordination with the winch.

A floating solar photovoltaic array having an energy management power control system configured to send power clipped by an inverter to the at least one powered accessory device which can be an aerator, a diffuser, a sub-surface agitator, a sub-surface water circulator, a sub-surface positioning/mooring system, a water quality sensor; a panel washer, or a bird removal system. The array has inflatable pontoons and an air manifold system which is powered by the solar photovoltaic modules can be used to adjust the angle of inclination of the solar photovoltaic modules to the sun. The powered accessories can also be powered by unclipped power or on-shore power or combinations thereof which can be controllably adjusted by the energy management control system over time.
