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 suspension system for a water craft, the water craft including a chassis which is at least partially suspended above or relative to at least a first hull and a second hull. The suspension system includes a first hull locating arrangement for at least partially constraining the first hull in a lateral, a yaw, a roll and a longitudinal direction relative to the chassis, the first hull locating arrangement comprising a first, a second, a third and a fourth link arranged to directly or indirectly connect between the hull and the chassis. The first, second and third links each extend in at least a lateral direction relative to the chassis and contribute to a lateral constraint on the first hull relative to the chassis. The second link is longitudinally spaced from the first link relative to the chassis to contribute to a hull yaw constraint on the first hull relative to the chassis. The third link is vertically spaced from the first and/or second link to contribute to a hull roll constraint on the first hull relative to the chassis. The fourth link extends in at least a longitudinal direction relative to the chassis to at least contribute to a longitudinal constraint on the first hull relative to the chassis and may be adjustable in length to vary the lateral spacing between the first and second hulls and thereby vary the overall width of the vessel.

A retractable pontoon boat has a deck, a starboard pontoon and a port pontoon, a center beam coupled to the underside of the deck and running substantially from bow to stern, a plurality of pivoting arms coupling the pontoons to the center beam, a plurality of bearings interposed between the deck and the pivoting arms, and one or more linear actuators for actuating the pivoting arms; wherein, in a first, retracted position, the pontoons are substantially underneath the deck; and wherein, in a second, extended position, the pontoons are substantially extended from underneath the deck.

An anti-wave floating photovoltaic device comprises a folding panel frame, an elastic support leg, a buoy and a self-locking support rod. The folding panel frame includes multiple unit frames and configured to be folded or unfolded by Miura folding. The adjacent unit frames are connected by a hinge mechanism and a photovoltaic panel is provided on the front side of the folded panel frame. The elastic support leg includes a V-shaped support rod and a U-shaped support rod with a changeable opening and providing elasticity through springs. The buoy includes a power buoy, an intermediate buoy and a driven buoy. The power buoy connects the intermediate buoy and the driven buoy through a rod.

A tipping bow has at least one articulated connection to a vessel behind and is connected to an anchoring. The tipping bow has a structural member attached to one or more attachment points at the bottom edge of the tipping bow. The anchoring is attached to an anchor attachment positioned behind and lower than the balance point of the tipping bow

The disclosure belongs to a field of hydraulic equipment, and in particular to an anti-rolling damping device for floating wind turbines. The specific technical scheme: low ends of buoys are connected with an upper surface of a support plate through a damping assembly, and the damping assembly includes a piston cylinder fixedly arranged on the support plate, a piston plate is slidably arranged in the piston cylinder, a piston rod is arranged at one end of the piston plate far from the support plate, the piston rod extends out of the piston cylinder and is fixedly connected with the buoys, and a plurality of first through holes are arranged on a side wall of the piston cylinder near the lower part. The buoys sink with waves, and the piston plate slides downwards in the piston cylinder.

An expandable and contractible boat comprises a first outer hull and a second outer hull symmetrically shaped and arranged with respect to one another. The first and second outer hulls are movable relative to one another, and each of the first and second outer hulls includes an outboard side portion, an inboard side portion, a bottom portion between the outboard side portion and the inboard side portion, and a concave chine portion connecting the outboard side portion and the bottom portion. A cross-section of each of the first and second outer hulls is recessed at the concave chine portion.
