An expandable pontoon boat includes a center section, a first side section, and a second side section. First and second telescoping assemblies connect the first side section to the center section, and third and fourth telescoping assemblies connect the second side section to the center section. The telescoping assemblies may be extended and retracted to extend and retract the first and second side sections from the center section, thereby widening and narrowing the boat, respectively.

A damping system is presented for damping an oscillation of a load on a fluctuant water surface. The damping system may include four buoyancy systems, two on each side of the load. Each buoyancy system may include two buoys, a lower frame and an upper frame.

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 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.

It relates to an urban craft, which belongs to the industrial sector of nautical vehicles for transportation of crew and passengers in general, composed of a speedboat (1) equipped with a central cab (2), a transparent roof (3), a honeycomb grid (4), an X-shaped structure (5), faceted areas (6), a catamaran hull (7), an inverted nose (8), a negative bow (9), engines (10), a propeller (11), seats (12), safety belts, airbags, acceleration and braking pedals (13), a steering wheel (14), a dashboard (15), a central console (16), a gear shift lever (17), armrests (18), cupholders (19), internet/Wi-Fi access, detachable tablets (20), a lateral boarding platform (21), headlights (22) and lateral arrows in the camera-based rearview mirrors (23), an air-conditioning system, a pneumatic suspension system with adjustable airbags and hydrogen-based shock absorbers, individual (rear and front) lateral doors (24), large gullwing lateral doors (25), an upper airfoil (26), a rear window (27), a foldable rear platform (28) with a step over the propelling devices (29), a central watershed system (30), a panoramic front window (31), a front hood with luggage compartment and access to fuel supply, a rear camera (32).

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.

Disclosed herein are hydrofoil vessels and systems integrated with renewable energy sources. In one aspect, the hydrofoil vessel includes one or more hulls, an omni-directional platform connecting the one or more hulls of the hydrofoil vessel. The omni-directional platform may include at least one of: a sail, a wind turbine, a solar panel, a hydroelectric motor, a hydrofoil controller platform, and a battery component. Also disclosed herein are methods and computer readable medium for controlling an omni direct modular hydrofoil vessel having one or more hulls integrated with renewable-energy sources.

A watercraft (1) is provided having a primary deck (3) that is carried on two primary buoyant members, such as pontoons (5, 7), that are substantially parallel to one another. The watercraft (1) includes a pair of deck extensions (13, 15) that are articulately connected to opposing sides of the primary deck (3). Each deck extension (13, 15) may comprise a number of extension segments (21, 23) that in concert form the deck extension. The watercraft (1) is operable between a deployed condition in which the deck extensions (13, 15) are substantially coplanar with the primary deck (3), thereby extending the primary deck (3) and a stowed condition, in which the deck extensions (13, 15) are raised substantially above the primary deck (3) with the extension segments (21, 23) of each deck extension alternately folded. The deck extensions (21, 23) are each connected to an auxiliary buoyant (25) member such that, when the watercraft (1) is in the deployed condition, each deck extension (13, 15) is carried on the buoyant member (25) connected thereto.

A marine vessel comprising: at least one buoyant tubular foil; and at least one baffle plate positioned about the perimeter of the at least one buoyant tubular foil so as to protrude into the flow of water passing by the perimeter of the at least one buoyant tubular foil, whereby to create a high-pressure zone fore of the at least one baffle plate and a low-pressure zone immediately aft of the at least one baffle plate, whereby to create a dense stream of supercavitated water immediately aft of the at least one baffle plate.
