Example implementations include a system and method of using plastic from bodies of water and creating a floating platform by collecting plastic from a body of water, cleaning the collected plastic, melting and compacting the plastic, molding a plurality of hexagonal blocks from the compacted plastic, stacking the plurality of hexagonal blocks, wherein a system of springs and an energy storage device is provided between each of the plurality of hexagonal blocks, and coating the stacked blocks with a non-toxic material. Through the use of various onboard functionalities, energy may be generated to regulate temperature and provide electricity, oxygen may be supplied, and water may be purified.

An apparatus including a fine-array porous material with a specific surface area higher than 10/mm, the specific surface area depending on different pore sizes, wherein the porous material comprises a plurality of pores having a substantially uniform size with a variation of less than about 20%, wherein the size is larger than about 100 nm and smaller than about 10 cm. The high-buoyancy apparatus can be part of a water vehicle such as a boat or a submarine, and the fine-array porous material is configured to reduce friction and/or control buoyancy. A conduit is also provided employing a fine-array porous material to reduce friction and/or control buoyancy. A garment is provided taking advantage of water repellant and/or UV/IR reflection properties of the fine-array porous material.

The present invention relates to a lightweight composite propeller for an outboard motor, wherein the propeller has a separate hub and blades which are easily repaired when damaged, improves fuel efficiency because a lightweight composite material is used therefor, and is easily manufactured in large quantities.

The instant invention relates to a buoy for the installation of underwater equipment, preferably used in equipment associated with petroleum underwater exploration, comprising an outer body, which has a top lid and a bottom lid, passage pipes, which extends internally along the entire length of the buoy, being provided also of a plurality of thrust elements arranged internally, which consist of gas microbubbles with quartz spherical body, vinyl material of closed cells and resin.

A fish skiff includes an inflatable floor made of high pressure drop stitch material; inflatable sides made of high-pressure drop stitch material formed at port and starboard sides of the inflatable floor, respectively; and a rigid transom formed at a rear portion of the fish skiff. The rigid transom is formed between the inflatable sides configured to have an outboard motor mounted thereon.

An inflatable structure that includes continuous longitudinal and axial curves, constructed to form a hydrodynamically designed performance platform for use as a performance water sports board, rescue board, or rescue sled, such as a stand-up paddle board, paddleboard, surfboard, PWC rescue sled, bodyboard, or other floating or dynamic platform. Alternatively, it may be adapted for use with additional structure to provide an inflatable hull and floor for a watercraft, such as a boat, raft, life-raft, rescue craft, or other floating or dynamic platform. Longitudinal stringers welded to opposing panels defining the interior volume of the inflatable structure are joined by welding, gluing, or lashing, and the shape of the stringers and the welding/gluing/lashing schedule can be employed to give the inflatable structure a highly customized curved shape.

A marine vessel includes pipes and tubular fluid conduits which are a part of a waste water management system. The waste water management system includes CPVC piping that is used to transport at least one of black water or gray water. The CPVC piping meets at least one fire endurance test set forth by the International Maritime Organization. Additionally, or alternatively, the CPVC piping meets at least one test set forth in IMO A.653 (16).

A structure for reducing the drag of a ship and its application thereof is provided. The structure for reducing the drag of a ship comprising at least one turbulence generator which is installed on the side surface between the widest section and the aft end or on the bottom surface between the deepest portion and the aft end of the ship. The arrangement of the turbulence generator can generate turbulence to reduce the drag of the ship, and thereby increase the speed of the ship or reduce fuel consumption as well.

The invention relates to a marine vessel cryogenic barrier which is formed of a plurality of individual panels, each panel being arranged to align with an adjacent panel on an inner surface of a hold space of a marine vessel and comprising a single coupling means at the centre of the panel and an impervious layer on a surface of the barrier facing the hold space.

A grip pack for providing a slip-resistant, water-resistant, and antibacterial surface to a piece of sporting equipment including at least three substrates printed with images. The images are printed with ultraviolet curable ink and the substrates are non-silicone. Each substrate includes a top printable layer, a middle adhesive layer, and a bottom removable layer. The top printable layer is printed with an image. The bottom removable layer is removable from each substrate printed with an image to expose the middle adhesive layer. The middle adhesive layer is configured to adhere the top printable layer to a surface of the piece of sporting equipment. Each substrate printed with an image and each image printed with ultraviolet curable ink is smoothed flat to conform to the shape of the piece of sporting equipment and provide a smooth protective layer with the slip-resistant, water-resistant, and antibacterial surface.
