An inflatable shuttle boat including a seat tube, a pair of exterior buoyancy tubes, and a pair of foot support tubes. The seat tube has an elongate, cylindrical outer surface that is centrally located and extends from a front end to an aft end, the seat tube sized for single-file, straddled seating of a plurality of riders on top of the cylindrical outer surface. The pair of exterior buoyancy tubes have an elongate shape providing exterior sides of the inflatable shuttle boat, each of the pair of exterior buoyancy tubes having a larger diameter and height than the seat tube and extend in a parallel disposition to the seat tube at right and left sides. The pair of foot support tubes have elongate shapes extending adjacent and parallel to the seat tube in coupled engagement between the pair of exterior buoyancy tubes and the seat tube.

A watercraft includes at least one float, a first frame supported by the at least one float, and a main panel affixed across the first frame. The watercraft further includes a second frame affixed to the first frame rotatably about a first edge and a second panel affixed across the second frame. In an embodiment, the first edge includes a shared frame member belonging to both said the frame and the second frame. In an embodiment, the watercraft includes a third frame affixed to the first frame rotatably about a second edge distinct from the first edge and a third panel affixed across the third frame. In an embodiment, the watercraft includes a shade rotatably affixed to a shade support edge member of the second frame and a shade panel affixed across the shade frame. The shade frame includes a pair of shade frame edge members rotatably affixed to the shade support edge member of the second frame.

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 onshore power or combinations thereof which can be controllably adjusted by the energy management control system over time.

The present disclosure provides an inflatable kayak. The inflatable kayak includes an inflatable floor having two ends defined upward; two inflatable gunwales arranged on the left and right sides of the inflatable floor, the height of the upper edge at both ends of the inflatable gunwale being higher than the height at the middle of the inflatable gunwale, allowing the height of the prow and the stern of the inflatable kayak to be no less than the height at the middle of the inflatable kayak; and a reinforcing assembly including a bottom reinforcing layer, a prow hatchway cover, and a stern hatchway cover, the bottom reinforcing layer at least covering the joints of the inflatable floor and the two inflatable gunwales. The prow hatchway cover connects the two inflatable gunwales at the prow, and the stern hatchway cover connects the two inflatable gunwales at the stern.

A device for collapsibly supporting a cover, comprising a mount and one or more resilient and substantially radial spars arranged to pivot relative to the mount, wherein a first end of the or each spar is associated with the mount and a second opposite end is configured to secure to an outer end of the cover, wherein in use, the device is movable from a collapsed state for stowage of the cover, to an open state, wherein: (a) the or each spar extends outwardly from the mount to spread the cover; and (b) tension is applied to an outer region of the cover, thereby drawing the second end of the or each spar downwardly such that the or each spar deflects and urges the cover upwardly and away from a plane defined by the perimeter of the opened cover.

The invention relates to a drop-stitch element in which at least one adhesive fold (9, 10) of variable depth is introduced into a flat drop-stitch component (8) such that the outer skin of the drop-stitch component can be folded on one side of the drop-stitch component or, according to the position of the fold, alternately on both sides of the drop-stitch component.
