The present invention comprises a method, apparatus, and system for modular mounting of typical pontoon or deck boat furniture and accessories including, but not limited to, seats, loungers, helm, bars, tables, fishing pedestals, sun pads storage bins, privacy curtains, lighting fixtures, and the like. The present invention allows customers to easily reconfigure the cockpit as needs or preferences change without leaving unwanted holes in the boat deck. The present invention also incorporates tool-free mounting devices arranged in a grid pattern that allows flexible placement and orientation of typical pontoon boat furniture and accessories. Further, the present invention permits streamlined manufacture by use of uniform, interchangeable inserts and modules.

A modular catamaran is a small body catamaran capable of being easily disassembled. The catamaran has approximate dimensions of ten feet-four inches (10′-4″) long and ninety-five and a half inches (95½″) wide having a pair of foam filled fiberglass pontoons. The top of the catamaran is fabricated with a welded aluminum frame that may be provided complete with seats and an engine.

A docking system for a boat includes spring-loaded bumpers that protrude from the bow of the boat, thereby enabling a boat operator to dock the boat against a vertical structure such as a seawall. Anchors are mounted with respect to the seawall to which ropes may be tied to secure the boat and maintain contact between the bumpers and the seawall. Anchors may be supported above the water level by floats, which automatically adjust the height of the anchors in response to changes in the water level.

A catamaran lifting apparatus is disclosed for lifting objects in a marine environment. The apparatus includes first and second vessels that are spaced apart during use. A first frame spans between the vessels. A second frame spans between the vessels. The frames are spaced apart and connected to the vessels in a configuration that spaces the vessels apart. The first frame connects to the first vessel with a universal joint and to the second vessel with a hinged connection. The second frame connects to the second vessel with a universal joint and to the first vessel with a hinged or pinned connection. Each of the frames extends upwardly in an inverted u-shape, providing a space under the frame and in between the barges that enables a marine vessel to be positioned in between the barges and under the frames.

A watercraft includes at least one float, a first frame supported by the at least one float, and a main panel affixed across the first frame. The watercraft further includes a second frame affixed to the first frame rotatably about a first edge and a second panel affixed across the second frame. In an embodiment, the first edge includes a shared frame member belonging to both said the frame and the second frame. In an embodiment, the watercraft includes a third frame affixed to the first frame rotatably about a second edge distinct from the first edge and a third panel affixed across the third frame. In an embodiment, the watercraft includes a shade rotatably affixed to a shade support edge member of the second frame and a shade panel affixed across the shade frame. The shade frame includes a pair of shade frame edge members rotatably affixed to the shade support edge member of the second frame.

A floating body for an offshore wind turbine includes: one first column; two second columns; two lower hulls connecting the first column to each of the second columns; and a beam member connecting the two lower hulls. The beam member is disposed within a height range between an upper surface and a lower surface of each lower hull.

An apparatus and methods according to the present invention provides a human powered catamaran-styled watercraft and methods of configuring and operating the watercraft. The watercraft generally comprises at least one hull in communication with a folding collapsible frame, wherein in the frame comprises a center rack pivotally joining hulls of hull sets to provide for common pivoting of the hulls during articulation of the watercraft, thereby the hulls and frame are in further communication through a at least one pivot pad which provides for slidable pivoting of the hulls during articulation of the watercraft. A method of folding and reversibly extending the watercraft to provide for optimized storage is provided. A method of operation of the watercraft to provide for articulation of the watercraft is provided.

Disclosed herein is a broad-based ship that may be facilitated for landing and taking off of multiple aircraft, in accordance with some embodiments. Accordingly, the broad-based ship may include hulls, decks, and elevators. Further, the hulls may be configured to be floatably disposable in a water body. Further, the decks may be supported on the hulls. Further, the decks may include a flight deck and a lower deck. Further, the flight deck may include airstrips configured for allowing landing and taking off of aircraft on the airstrips simultaneously. Further, the elevators may be configured for transporting the aircraft between the lower deck and the flight deck simultaneously. Further, the transporting may include transferring the aircraft from the lower deck to the flight deck simultaneously. Further, the taking off of the aircraft simultaneously may be based on the transferring.

A method of controlling a plurality of marine drives on a multi-hull marine vessel includes determining, based on steering information, that the multi-hull marine vessel is entering a turn and then receiving a running trim position for each marine drive. A trim position of at least a portion of the plurality of marine drives is then adjusted from each respective running trim position so as to induce roll of the multi-hull marine vessel during the turn.

A section of a pontoon for a pontoon boat includes a tubular body having a first end and a second end. The second end is configured to being coupled to another section of the pontoon. An end cap is coupled to the first end of the tubular body and a profile having at least two curvatures. The at least two curvatures include a first curvature defined by a first radius and a second curvature defined by a second radius.
