Abstract: Accessories for boats, and in particular folding inflatable boats, are described. The accessories may be installed and removed from the boats rapidly and easily, hence not impeding folding of the boats for transport or storage.

Abstract: A new and improved contamination-control mat assembly which has a plurality of adhesive-coated sheets disposed upon the upper surface portion of the contamination-control mat assembly, and a new and improved polystyrene frame member, having an acrylic-rubber anti-slip backing member applied thereto, disposed upon the undersurface portion of the contamination-control mat assembly, wherein the polystyrene frame member and the acrylic-rubber anti-slip backing member are integrally affixed together by means of a coextrusion process.

Abstract: Boats adapted for multiple purposes are detailed. Versions of the boats may have performance characteristics and equipment necessary to qualify as rescue boats while normally maintaining appearances appropriate for placement on, for example, yachts as tenders or similar boats. Covers or other transformative materials may be used to modify the appearances of the boats when needed as rescue craft.

Abstract: Watercraft flooring including both inflatable and non-inflatable elements is detailed. Such flooring may be designed to support substantial loads while maintaining its lightweight nature and contributing to its longitudinal and lateral rigidity. Some versions of the flooring have an inflatable core with slats positioned both above the upper surface of the core and below the lower surface of the core at regular intervals along its length. The slats extend laterally across substantially the width of the core, effectively sandwiching portions of the core between them.

Abstract: Access openings and ramps for boats are detailed. Collar assemblies may include segments split in one or more ways and adapted to unfold, or otherwise open, along the splits to form ramps extending outward from the hulls of associated boats. Alternatively, portions of the segments may be removable. Boats with rigid hulls and foam (or other) fenders may include hinged segments of the hulls and fenders that open both to expose access openings into the boats and create ramps.

Abstract: Alternative collar assemblies for use with watercraft including rigid-hulled boats are described. The collars may include both foam materials and one or more inflatable compartments, thereby offering multiple advantages over existing foam or inflatable collars. Optionally included in or on the collars are reinforcing material (such as but not limited to Kevlar) and an abrasion-resistant coating surrounding the foam and inflatable compartments. Similarly, compartments comprising the collar optionally may be nested.

Abstract: Armored protective panels for inflatable (and other) boats are detailed. The panels themselves may be inflated, either separately or together, for deployment and hence need not normally impede navigation or performance of the boats. If relatively flexible anti-ballistic materials are selected as components, the panels may be designed to collapse into rolls when not inflated. Alternative panels may include stealth or other non-anti-ballistic materials or be designed for use with objects or vehicles other than boats.

Abstract: An inflatable pneumatic boat with a non-flat rear board.An inflatable pneumatic boat comprising a rear board (5) extending transversely and approximately vertically between two lateral floats (2), characterized in that the rear board (5) is a non-flat one-piece component and has two lateral panels (6), each connected to a float (2), and a central panel (7) offset to the rear beyond the rear edge of the bottom (4) of the boat.
