A water mat for a boat and a boat. The boat may be a pontoon boat. The water mat may include a cut-out. The cut-out may be formed in a forward side of the water mat, with the forward side of the water mat is connected to the stern of the boat such that the outboard motor is positioned in the cut-out of the water mat. A flexible connecting sheet, that is configured to connect the water mat with the boat, may be attached to a connection side of the water mat and extend along the connection side of the water mat.

A hull locating arrangement for a vessel is disclosed that has a body at least partially suspended above at least a first hull by at least one support. The hull locating arrangement includes for the first hull a forward locating linkage and a rearward locating linkage, each of the forward locating linkage and the rearward locating linkage being connected between the first hull and the body to together constrain said hull in the lateral, longitudinal, roll and yaw directions relative to the body. The forward locating linkage includes a forward radius arm and a drop link, the drop link being pivotally connected to the radius arm. The rearward locating linkage includes a rearward radius arm connected between the body and the first hull.

A ground effect craft having a ground effect wing, a plurality of sponsons, and a control system is disclosed. The ground effect wing may include a fore ground effect wing and an aft ground effect wing. The ground effect wing may generate a stabilizing moment on at least one sponson to stabilize the around effect craft. The plurality of sponsons may be dynamically coupled to the body. The plurality of sponsons may be dynamically coupled to each other. The dynamic coupling may permit the sponsons to move relatively independent of the body and each other, thereby stabilizing the ground effect craft. The ground effect craft may include a stabilizing wing.

A floating solar power plant (1) comprising a floating carrier module (3), wherein the floating carrier module (3) comprises photovoltaic modules (5) for electric power generation and a floating structure (50) provided with one or more buoyancy elements (9) extending into the water. The floating structure (50) further comprises a flexible means (53, 57, 57a, 57b) providing a change of shape of the floating structure when exposed to external forces, as the floating structure (50) comprises a plurality of interlinked rigid elements (51), wherein the rigid elements (51) are linked together with flexible means comprising flexible joints (53) to form a chain that encloses a center area (55). A method is also disclosed.

The present invention provides a hull-conversion device and method for modifying the underside of a watercraft, more specifically a multihull watercraft. The hull-conversion device comprising a water diverting surface, a kinematic assemblage, and a frame. The hull-conversion device may be operable to adjust the watercraft's characteristics in displacement mode and planing mode. The hull-conversion device may function to provide a more stable, controllable, and efficient platform for operating a multihull watercraft, and provide a suitable wake for towable water sports.

Power generated by a wind turbine is applied to drive reverse osmosis (RO) desalination. Rather than discharging the brine back into the ocean, it is concentrated and modified through industrial-scale processes to produce sodium hydroxide (NaOH). Direct air capture of CO.sub.2 occurs when liquid NaOH, created from the RO desalination brine, is conveyed to the rotor hub and emitted from the wind turbine blades to react with CO.sub.2 in the atmosphere. The power of an offshore wind turbine is used for the onboard production of fresh water to supply shoreside water needs, or water may be electrolyzed to produce hydrogen while adding the vital process of CO.sub.2 sequestration to the ocean.

A suspension system for a vessel with at least one left hull, at least one right hull and a chassis, the suspension system including respective front left, front right, back left and back right support rams connected between the chassis and the respective hull and including a respective compression chamber which with a respective diagonal conduit forms a respective support compression volume; first digonal support interconnection valve (59) selectively interconnects front left and back right diagonal conduits (61, 64) and support compression volumes second diagonal support interconnection valve (60) selectively interconnects front right and back left diagonal conduits (62, 63) and support compression volumes, a deck attitude control system (100) comprising a controller (102), sensors, first and second diagonal actuating arrangements (25, 26) for controlling fluid flow across the respective diagonal support interconnection valve to control a position of a point on the chassis relative to a reference (5).

There is provided an amphibious vehicle for use on land and water comprising lateral floaters which increases the stability of the vehicle when in water. While on land, the lateral floaters may be retracted within the body of the vehicle to reduce the width of the vehicle.

A boat may have a deck and a plurality of pontoons or hulls supporting the deck of the boat. The boat may include a starboard side pontoon, a port side pontoon, and possibly a middle pontoon. A positioning assembly may be provided with one or more of the foregoing pontoons. Each of the positioning assemblies may comprise a link assembly and an actuator provided to position the toon between the retracted position and the extended position. The boat may further include a leveling control system having a controller and a level sensor configured to detect an attitude of the deck, the controller in communication with the actuators and cause actuation of either or both of the actuators to extend or retract the port side toon and/or the starboard side toon based on data received from the level sensor indicative of the deck attitude.

A ground effect craft having a ground effect wing, a plurality of sponsons, and a control system is disclosed. The ground effect wing may include a fore ground effect wing and an aft ground effect wing. The ground effect wing may generate a stabilizing moment on at least one sponson to stabilize the ground effect craft. The plurality of sponsons may be dynamically coupled to the body. The plurality of sponsons may be dynamically coupled to each other. The dynamic coupling may permit the sponsons to move relatively independent of the body and each other, thereby stabilizing the ground effect craft. The ground effect craft may include a stabilizing wing.
