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.

A stabilization system for a marine vessel includes at least two inflatable bladders configured to be attached to the marine vessel, a gyroscopic sensor configured to sense an angular orientation of the marine vessel, and a controller configured for inflating and deflating the at least two inflatable bladders responsive to the angular orientation sensed by the gyroscopic sensor.

Disclosed is a boat including a bottom bordered radially externally by a wall which includes an inflatable and foldable front wall, an inflatable and foldable side wall, and a rear wall. The boat includes at least one inflatable and foldable longitudinal support parallel to the side wall, the support including an inflatable tube and a foldable upper connection which connects the tube to the upper part of the side wall, the upper connection extending longitudinally along the side wall and forming during use a surface P capable of receiving an element.

A rigid-inflatable boat (RIB) includes a solid hull and an inflatable tube, forming a part of a gunwale. The boat includes a tube air filling system with an air conduit arranged to communicate with air pumping system and a tube, where the air conduit extends along at least a portion of the tube. The solid hull includes a gunwale portion, forming a part of the gunwale, where the air conduit is enclosed in the gunwale portion.

Disclosed is a boat including a flexible bottom bordered radially towards the outside by a wall which includes an inflatable and flexible front wall, an inflatable and flexible lateral wall, and a rear wall. At least one part of at least one of the lateral wall and of the front wall is constituted by a first inflatable element configured as a panel having two parallel planar faces, a second inflatable element of which the cross section is in the form of a D with a planar portion, and a flexible assembly device, the second element being situated radially towards the outside of the boat with respect to the first element, the assembly device maintaining the planar portion of the second element in contact with one of the planar faces of the first element.

Disclosed is a buoyancy tube for a life raft having: a first panel including: a first panel top edge and a first panel bottom edge, the first panel top edge defines a first repeating pattern, and the first panel bottom edge defines a second repeating pattern that is a rotated version of the first panel top edge; a second panel that has a same shape as the first panel, the first and second panels connected by a first elongated seam and a second elongated seam that are non-overlapping with one another, the first and second panels, when connected, define outer an inner boundaries of the life raft, the outer boundary defines an outer polygon having outer sides and the inner boundary defines an inner polygon having inner sides such that each of the plurality of outer sides is parallel with one of the plurality of inner sides.

A stabilization system for a marine vessel includes at least two inflatable bladders configured to be attached to the marine vessel, a gyroscopic sensor configured to sense an angular orientation of the marine vessel, and a controller configured for inflating and deflating the at least two inflatable bladders responsive to the angular orientation sensed by the gyroscopic sensor.

A marine surface vessel includes a boarding pole for maritime boarding actions and the boarding pole is at a first end of the boarding pole, attached to a deck of the vessel via a flexible joint. The vessel includes a holding device presenting, or being arranged to present, a holding cavity arranged to receive, in a non-erected condition of the boarding pole, a boarding engagement device at a second end of the boarding pole, which second end is opposite to the first end.

A system for controlling the position and orientation of a floating solar array, having: (a) a floating solar array; (b) a plurality of retractable, bi-directional thrusters mounted to the floating solar array and extending below the floating solar array; (c) a control system on the floating solar array for controlling power level of each of the plurality of thrusters, and (d) a power cable connecting the floating solar array to an onshore grid by way of a power cable connector at a bottom central location on the floating solar array. Submerged baffles, perimeter floats and a method of stowing the floating solar array in high winds by rotating the floating solar array into a direction perpendicular to the direction of the high winds are also included.

An inflatable flotation chamber comprising a seamlessly constructed flexible tube, sealed ends, and a valve for inflation and deflation. Said chamber characterized in that it can be inflated to a relatively high pressure, giving functional shape and independent structural rigidness to the chamber. A watercraft characterized by one or a multitude of such inflatable flotation chambers. A method of constructing such an inflatable flotation chamber.
