A water mat is provided. The mat includes a first buoyant layer, a netting layer and a second buoyant layer. The netting layer may be adhered in between the upper and lower foam layers. The netting layer may include crisscrossing fibers having a first set of fibers substantially parallel relative to each other and a second set of fibers substantially parallel relative to each other. The first set of fibers crisscross with the second set of fibers, and are thereby perpendicular relative to the second set of fibers. The netting layer provides additional strength to the mat.

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.

The present disclosure is directed to a personal watercraft, such as a standup paddleboard, provided with a viewing window that allows the user to view the underwater environment. The viewing window may be watertight and constructed from at least two durable, transparent panels. The area between panels may be sealed from air and water infiltration. A user may add waterproof lights to the bottom of the standup paddleboard in order to allow viewing of the underwater marine environment at night.

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.

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 water mat is provided. The mat includes a first buoyant layer, a netting layer and a second buoyant layer. The netting layer may be adhered in between the upper and lower foam layers. The netting layer may include crisscrossing fibers having a first set of fibers substantially parallel relative to each other and a second set of fibers substantially parallel relative to each other. The first set of fibers crisscross with the second set of fibers, and are thereby perpendicular relative to the second set of fibers. The netting layer provides additional strength to the mat.

Protective polymer covers for metal equipment are disclosed. The metal equipment is generally used with wire ropes, and the protective polymer covers provide a smooth protrusion free surface which is suitable for contact with a synthetic line. The protective polymer covers are shaped to conform to an outer peripheral surface of the metal equipment, and include at least one cover section having at least one means for connection at each of a first end portion and a second end portion. The protective polymer covers are composed of a thermosetting cast polyurethane having a Shore D hardness of greater than about 60 or a Shore A hardness of greater than about 85.

A High-Density Polyethylene (HDPE) marine boom includes an elongated generally cylindrical shell including inner and outer layers formed from HDPE with the same formulation. The inner layer includes at least 2% carbon black by mass and the outer layer does not include carbon black. The outer layer includes a colorant with ultraviolet stabilizers and the inner layer does not include the colorant. The inner layer is thicker than the outer layer and they have been coextruded to form a unitary body. First and second caps, each including a radially extending circumferential annular flange, formed from the same material as the outer layer are fusion welded to the shell across the full thickness and around a full circumference of first ends and second ends of the shell and form a watertight seal. A floatation billet is in the shell. A lug plate for the HDPE marine boom is also disclosed.
