A chassis module for a vessel, the chassis module having: a frame; a left linkage arrangement including at least one left hull connection and configured to movably couple the frame to at least one left hull when the left hull connection is connected to the left hull; a right linkage arrangement including at least one right hull connection and configured to movably couple the frame to at least one right hull when the right hull connection is connected to the right hull; at least one left support mount and at least one right support mount for respectively connecting to a respective support providing support for the frame relative to the respective left or right hull when hulls are connected to the hull connections; the frame having a plurality of body attachments to facilitate attachment of the chassis module to a body of a vessel.

Implementations described and claimed herein provide an underwater vehicle includes a vehicle body having a frame enclosed by a fairing. The vehicle body extends between a proximal end and a distal end and defining an interior. A nose is disposed at the proximal end of the vehicle body. The nose has a tow system configured to move between a tow position and a stow position. A propulsion system is disposed at the distal end of the vehicle body. The propulsion system includes a plurality of control fins and a thruster. A power distribution system is housed in the interior of the vehicle body. The power distribution system includes a first power system housed in a first pressure vessel and a second power system housed in a second pressure vessel. The first pressure vessel is isolated from the second pressure vessel.

A truss system may include a plurality of beams. Each beam of the plurality of beams may have various cross-sectional sizes in a same plane. Additionally, the plurality of beams may have a geometric arrangement such that a structural weight at required strength level may be reduced to achieve optimal design.

A hybrid personal watercraft combines features of pontoon boats and deck boats, in a cost-effective and versatile package. The watercraft includes port and starboard sponsons which combine a pair of outboard flotation cavities. A space below the deck and above the hull bottom creates at least one, and potentially up to three additional flotation cavities, which may also be used as storage areas accessible by an access door in the bow of the watercraft and/or a set of hatches in the deck. The watercraft may be efficiently produced assembled from polymer materials, such as thermoplastic polyolefin (TPO).

A water vessel that may be assembled from a single piece of material via a fold and lever/clamp system that allows a user to assemble, use, and later disassemble the vessel into a packed form as well as assemble the vessel from the packed form.

A load-bearing frame structure for a maritime vehicle includes two support plates, a deck plate structure, a front bulkhead structure, and a back bulkhead structure. Each of the support plates has a front edge, a back edge, a top edge, and a bottom edge. The support plates can be angled relative to each other and connected to each other at the top edges thereof forming an inverted V-shape. The support plates can alternately be parallel to each other in a vertical orientation. The support plates each have one or more cut-out sections. The deck plate structure connects the two support plates proximate the bottom edges of the support plates. The front bulkhead structure connects the front edges of the support plates, and the back bulkhead structure connects the back edges of the support plates.

A semisubmersible floating platform (1) for supporting at least one wind turbine, comprising four buoyant columns (3), each of them being attached to a ring pontoon (2); a transition piece (4) configured to support one wind turbine, disposed on the buoyant columns (3); and a heave plate (5) assembled to the internal perimeter of the ring pontoon (2). The ring pontoon (2) comprises four pontoon portions forming a quadrilateral-shaped ring pontoon (2) wherein the first end of each column (3) is attached to a respective corner of said quadrilateral-shaped ring pontoon (2). The heave plate (5) is located in the internal perimeter of the ring pontoon (2), both defining a hollow. The pontoon (2) is preferably divided into a plurality of compartments or construction blocks that may be filled with fixed ballast, such as concrete. The transition piece (4) has four arms arranged in star configuration and protruding from a central point at which the wind turbine is located, the connection between the transition piece (4) and the columns (3) being designed to be located above the sea splash zone. Each of the buoyant columns (3) comprises at least one ballast tank configured for allocating sea water in order to adjust the draft and to compensate for the inclination of the platform (1), said at least one ballast tank comprised in each column (3) being independent of the at least one ballast tank of the other columns (3).
