Systems and method for compensation of motions of a floating structure, which includes a lifting system with a working platform supported by its actuators driven along vertical axis, where the foremost and the aft-most units are paired with each other providing a self-leveling movement; and a balance system, which can freely deviate from its position relative to the deck, with its own actuators and which is arranged to at least one side of the working platform, providing an even distribution of weight enabling the working platform to remain upright and steady, regardless of the floating structure. The lifting system is associated with the balance system by the plurality of arrangements of motion units, which assure the substantially constant angle between the working platform and the working frame, providing free linear movement relative to the working frame regardless of the base structure and the floating structure.

A vessel with three platformsan outer hull, an inner deck hull and a passenger carriage, having four independent suspension systems there between so as to accommodate for the multi axis movements of the outer hull. This multi axis suspension system spread between the three platforms will offer the passenger carriage stability against the pitch, yaw and roll rotations a vessel makes as it twists and turns going up and down the slope of a wave as well as the heave, sway and surge movements induced by the waves pushing the vessel around and or the ship sliding down the face of a wave.

A powered swim platform for improving accessibility to a swim deck of a water-sports boat or other watercraft. The powered swim platform includes a platform driven by an actuator. The actuator can rotate the platform between stowed and deployed configurations to assist a user in mounting or dismounting the swim deck of the water-sports boat or other watercraft.

An adjustable height boat includes a lower deck and an upper deck, movable relative to the lower deck. The upper deck is configured to support one or more passengers and facilitates movement of the passengers in an upright position. The adjustable height boat include a plurality of telescopic support legs. In one embodiment, the plurality of telescopic support legs includes four columns having actuators therein, which are configured to extend and retract in response to signals received from a controller to move the upper deck from a first position in which the upper deck is a first height above the lower deck and a second position in which the upper deck is a second height above the lower deck.

A swim platform is built into a side of a boat, either the port or starboard side. The swim platform is raised and lowered by a mechanism that fits within the side wall of the boat beneath the gunnel. The swim platform is raised when the boat is underway to prevent water intrusion, provide safety, and reduce drag; while the swim platform is lowered, for example, when the boat is anchored for enjoyment of the boaters using the boat.

A superstructure-integrated backspray mitigation system for yachts including an aft spoiler secured to the vessels hardtop for directing airflow about the hardtop downwardly into the aft cockpit area to interfere with, mitigate and eliminate the natural reverse backspray created by the low-pressure region behind the yacht. The spoiler protrudes from the hardtop and includes at least one air ducting channel directing airflow at select angles into the cockpit area presenting a protective shield preventing the backspray from entering the cockpit. An optional pivotal panel member selectively enables operation of the spoiler.

A quick connect system for a boat connects the deck of the boat to the hull of the boat. The deck sits on top of the hull. The hull is preferably inflatable, and preferably in two opposing, symmetrical hull sections being a left hull and a right hull. Each hull preferably has two parallel inflatable tubes that extend from the rear of the hull to the front. The deck is preferably a multi-piece system having a spaced apart front deck rear deck. An elevated casting platform extends between the deck sections and is supported by legs. The hull and deck have a series of aligned rigid tube receivers and loops that receive a series of rails. The rails are slideable into the loops and rigid tube receivers to secure the deck to the keel, and to provide a quick mechanism to disassemble the deck from the tubes.

A stern platform assembly for an outboard propelled boat, comprising a pair of side support wings, a movable platform arranged adjacent to the side support wings, and a motion mechanism housed within each of the side support wings and carrying the movable platform, wherein the movable platform is movable between a terminal elevation position, in which it is arranged adjacent to the top of the side support wings, and a terminal lowering position, while keeping a predetermined orientation with respect to the side support wings and keeping a closeness relationship with them, and wherein, when viewed in plan view, the assembly encompasses a room circumscribed on three sides by the movable platform and by the side support wings.
