A shallow draft sampling raft including a bow, and a stern, in which the bow is an opposite end of the raft from the stern. The raft also includes a top surface, a bottom surface, and a plurality of longitudinal stringers. The plurality of longitudinal stringers are attached to an inner face the bottom surface and run from the bow to the stern. A top surface is also attached to the longitudinal stringers.

A stable fishing raft that is easily transportable to the water without a trailer and has a deck large enough to easily and securely carry fishing gear. The deck and bottom are flat, and the sides are perpendicular to the deck and bottom. The deck is connected to the bottom at the bow and stern with a circular arc. The core of the raft is a buoyant foam, preferably polyurethane, and covered in a water-resistant resin, preferably polyethylene. The raft is steerable and propelled by paddle or trolling motor that attaches to a removable motor mount. In a preferred embodiment the raft has a recessed accessory track and a series of recessed rings on the deck to receive the bottom edge of a bucket and hold it in place as a seat. Rafts can be joined together with couplers.

A modular multipurpose offshore operation platform comprises a floating structure having a lower portion submerged below the surface of the sea, and a platform structure provided at an upper surface of the floating structure. An integrated work platform comprises at least two modular multipurpose offshore operation platforms. Framework structures of two adjacent operation platforms are detachably and fixedly connected, and floor boards of the operation platforms collectively form a deck. A transportation method transports goods to the platform by means of a hoist, and a hoist bracket with a rotating roller. The platform can achieve standardized production, and is flexible and has multiple functions.

A shallow draft sampling raft including a bow, and a stern, in which the bow is an opposite end of the raft from the stern. The raft also includes a top surface, a bottom surface, and a plurality of longitudinal stringers. The plurality of longitudinal stringers are attached to an inner face the bottom surface and run from the bow to the stern. A top surface is also attached to the longitudinal stringers.

A system and method for lighting a surface, for example a deck of a boat, spa, swim spa, pool, watercraft or vehicle, using backlighting such that decorative or other desired patterns of light may be created by forming cuts, outlines, thin sections, or voids in an overlay that is applied to the lighted surface, allowing light to pass through or around portions of the overlay material. In an exemplary use of the system and method of the invention, the surface may be the surface of a boat or spa. The surface may comprise transparent or translucent materials, allowing light from a first side of the decking, or light that is generated within the decking, to pass through the decking and to emanate from a second decking side, where the light may be blocked, partially blocked, or allowed to pass through the overlay material in any desired pattern or shape.

A foam product includes a foam core, a soft skin covering the foam core, and a base structure on which the foam core is disposed. The foam core of expanded beads has an outer surface on which some outermost beads of the expanded beads are exposed and bulging outward with different heights to form a bubbly texture. The foam skin has an inner surface attached to the outer surface of the foam core, and has at its inner surface a plurality of concave cavities each matedly surrounding a respective one of the bulging, outermost beads on the outer surface of the foam core.

A method for manufacturing an integrated hull by using 3D structure type fiber clothes and 3D vacuum infusion process includes: sequentially stacking at least one first fiber cloth, at least one core material and at least one second fiber cloth on a mold; deploying structural materials on the second fiber cloth; stacking the third fiber clothes to cover the structure materials and a part of the second fiber cloth, whereby the first fiber cloth, the core material, the second fiber cloth and the third fiber clothes are formed to a lamination; determining a pipe arrangement of vacuum pipes and first and second resin pipes; deploying a vacuum bag on the lamination and covering the first and second resin pipes and the vacuum pipe; executing the 3D vacuum infusion process; curing the resin; and executing a mold release process to complete an integrated hull.

Marine fender for impact protection comprising a core of closed cell foam, wherein said core comprises at least one chamber substantially entirely surrounded by said closed cell foam and enclosing an elastically deformable closed object. The marine fender can comprise an intermediate layer that at least partly encloses the core and/or a coating that at least partly covers the intermediate layer.

This invention relates in general to an improved foam blank for a surfcraft and in particular, to an improved reinforced foam blank and a method of manufacturing the same. The foam blank has a top blank face, an opposed bottom blank face, a pair of shaped rails extending between the opposed top and bottom blank faces at blank face edges, an enclosed core space and a midline axis extending between a nose region and a tail region and which divides the foam blank into two substantially equal regions. At least one longitudinally extending slotted aperture is formed in any one or more of the top, the bottom or the rails, such that the slotted aperture extends into the enclosed core space. At least one flexible spine is bonded to be fixed within the at least one longitudinally extending slotted aperture.

A method of manufacturing a boat hull comprising: forming a foam mold of a predetermined shape and size from one or more pieces of foam; cutting, into said foam, at least one “C” channel running in a longitudinal or a lateral direction within the foam; and coating said foam with at least one layer of reinforcing fiber and resin.
