Abstract: A watercraft includes a hull and a water diverter. The water diverter comprises at least one first deflector configured to direct water upward and outward from the hull of the watercraft to create a wave. The water diverter may include a support structure in the shape of a hollow tube for the first deflector, and a second deflector positioned above the first deflector. An entanglement system for defending watercraft includes a main cable attached to the watercraft and at least one strand section. Each strand section includes a connector and a plurality of strands attached to the connector, and each strand section is attached to the main cable. A defense system for watercraft can include both a water diverter and an entanglement system.

Abstract: As typically embodied, the present invention's add-on device includes two wedge-shaped structural components that are oppositely congruent and symmetrically connected. In profile, the device describes a pair of nearly triangular quadrilateral figures that are enantiomorphs (mirror images) with respect to the linear bisector (mirror line) at which they join. The device's V-angular upper surface defines the same V-angularity (“deadrise”) as does a V-angular hull bottom, the device thus fitting beneath the hull bottom. The device's V-angular lower surface defines a different angularity, which is imparted to the hull bottom when the device is attached thereto. According to typical inventive practice, the device alters the hull bottom's V-angularity by at least 1° and, at least, covers approximately 100% of the hull bottom's widthwise expanse along approximately 50% or more of the hull bottom's lengthwise expanse.

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: The underwater exterior surface of a watercraft is covered by a deformable protective covering formed from compartmental sections that are dimensionally sized, shaped and mechanically connected to each other for effective attachment of the assembled covering to and removal from the hull of the watercraft. The protective covering is of a cross-sectional construction arranged to provide protection against the damaging effects of underwater explosions by minimizing related adverse physical effects on the entire hull of the watercraft as well as mechanical and electrical components associated therewith.

Abstract: A set of three shield devices in which a monohulled war vessel is defended against projectiles. The devices being deployed aft of the helicopter hangar, centered on the fore and aft longitudinal axis of the hull. The devices capable of activation for projectile deflection in any configuration or independently. Further, the structure of the shields is composed of suitable plastic materials.

Abstract: A complete section of pontoon bridge carried on a support structure that is applied to existing apertures on the cargo box of military trucks. The section of pontoon bridge forms a complete weather proof cover for the cargo box and leaves the cargo area free to carry other cargo. Bullet resisting pontoon bridge decking form the sides of the weather proof cover and an inverted pontoon forms the roof. With the section of pontoon bridge removed from its s truck, an armored assault boat can be constructed from the pontoon and decking. The decking is bolted together to form a cabin which in turn is inserted in the upright pontoon. With an outboard motor applied to the stern a motorized-armored assault boat is completed.
