Hull structure made of composite material that includes a hull with high thickness “single skin” monocoque plating without reinforcements and an internal stiffening structure (1) formed by a deck (2), two opposing transverse bulkheads (3) and more cradle-shaped load-bearing elements (5) to support components or machinery intended to be housed on board said hull structure. Advantageously, the above-mentioned cradle-shaped load-bearing elements (5) are supported at the respective internal portions of said opposite transverse bulkheads (3) only at their opposite head ends (5b).

A drive arrangement for a marine vessel. The drive arrangement includes an outboard drive unit provided with at least one propeller, wherein the outboard drive unit is configured to be arranged on an outside of a transom of the marine vessel and to be connected via an opening in the transom to further parts of the drive arrangement arranged inside the marine vessel; and a supporting carrier configured to be arranged at the opening in the transom for fastening and support of the outboard drive unit so as to take up thrust and steering forces from the outboard drive unit when the drive arrangement is installed and used for propelling the marine vessel. The drive arrangement includes a supporting frame structure configured to be fixed to a supporting hull structure arranged on an inside of the marine vessel forward of the transom. The supporting frame structure extends aft-wards from or along the supporting hull structure to the opening in the transom. The supporting carrier forms part of or is firmly fixed to the supporting frame structure.

The invention relates to a method for producing a vessel hull (1) for use as a hull of an FPSO or FSO, comprising producing a vessel hull with a stern portion (2), a bow portion (3) and a central portion (4), arranging a deck (6) on the hull, for supporting processing modules, arranging hydrocarbon storage tanks inside the hull, providing the hull with an anchoring connection arrangement (7), characterized by arranging process module reinforcements (8) in the deck for supporting the hydrocarbon process modules, providing both longitudinal hull sides with mooring line connection reinforcements (9) at or near the bow portion, arranging riser connection reinforcements (10, 14) on one or more longitudinal hull sides, in between the mooring line connection reinforcements in longitudinal direction, for a riser balcony (28, 29), and providing the bow portion with turret reinforcements (11, 12).

An article of manufacture including molded-in cavities that permit the installation of recessed trolling motor foot pedals and seat pedestal bases in such a manner that allows water to drain away from thereof so as to prevent the accumulation of standing water. The article of manufacture includes a body, wherein the body is a plastic molded boat hull comprised of numerous molded-in cavities and molded-in features to create an interior layout that is comparable to a conventional boat built of aluminum or fiber reinforced plastic.

A system for mounting equipment to a vessel's hull is disclosed. The system comprises a first stringer and a second stringer, where each stringer is attachable to the inside of the vessel's hull. The system also includes a layer of adhesive attaching both stringers to the inside of the vessels hull. Both stringers have a top cap for attaching equipment. Additionally, each stringer has a first vertical side wall connected to a first end of the top cap, a second vertical side wall connected to a second end of the top cap, and two flanged portions. A first flanged portion connects to a lower end of the first vertical side wall, and a second flanged portion connects to a lower end of the second vertical side wall. The system has an open side portion at the bottom end of both stringers.

A boat hull has one or more track systems integral with a main body of the boat hull, each track system having a longitudinally extending channel comprising: a longitudinally extending channel body; and a longitudinally extending channel opening in communication with the channel body, wherein the channel body is wider in cross-section than the channel opening, the channel body is adapted to receive a fastener which has a portion that is wider in cross section than the channel opening, thereby preventing the fastener from being withdrawn from the channel body through the channel opening, and wherein the fastener can be selectively secured to the track system at a selected longitudinal position. The track systems can be used for mounting boat hull structural parts and other parts and accessories.

A bracket for mounting a thruster to a boat includes horizontal and vertical members disposed at right angles to each other. The horizontal member includes an enclosure which contains a lamp. A thruster is mounted to the horizontal member, and the vertical member is affixed to the transom of a boat. The thruster is therefore held in spaced-apart relation to the boat, optimizing the flow of water through the thruster, and minimizing the amount of space required, on the transom, for installation of components. The horizontal member, and one of the connectors holding the vertical member to the boat, are hollow, allowing wires to extend into the horizontal member, to provide power to the thruster and the lamp.
