A WaveAnchor and method of installing the WaveAnchor to stabilize the wave-induced rocking action of a boat, vessel or other floating platforms is provided. The present invention includes a method of creating downward pull on the WaveAnchor cables, which serves to stabilize a rocking boat or vessel, and further for harvesting the force of this downward pull for purposes of electrical generation by attaching the rope or cable from the WaveAnchor described above to a rotating shaft on the floating platform. Critical to this invention is the deployment of many such WaveAnchor devices around the edges of the floating platform, each of which transfers power to the central shaft. The power generation achieved by the WavePower platform with its deployed WaveAnchors is enhanced by the use of a floating platform which is not stable as it naturally rocks with wave action.

A sea anchor includes a textile tube and a resiliently flexible support. The textile tube may include a first end and a second end. The first end may have a rim defining a mouth and the second end may be closed. In various embodiments, the resiliently flexible support is coupled to the first end of the textile tube. The resiliently flexible support, in response to the sea anchor being deployed, may be configured to expand the mouth and retain the mouth open. In various embodiments, the textile tube has a conical shape, with the mouth of the first end being a base of the conical shape and the second end being a point of the conical shape. The resiliently flexible support is a ring coupled to the rim of the first end of the textile tube, according to various embodiments.

A non-lethal naval vessel interdiction weapon is provided. The non-lethal naval vessel interdiction weapon includes a hydrodynamic hull, guidance and delivery systems housed in the hydrodynamic hull with the delivery system being controllable by the guidance system to drive a naval vessel impeding payload toward a target and a deployment system. The deployment system is configured to prepare the hydrodynamic hull for payload deployment and to deploy the naval vessel impeding payload toward the target following hull preparation.

A water-buoyant structure formed from concrete is disclosed. The structure comprises an outer wall that surrounds a perimeter of the structure and an inner wall separated from the outer wall by a cavity, such that the cavity extends for the perimeter of the structure. Separating the cavity can provide sufficient buoyancy to the structure to allow 5 the structure to float. The combination of outer and inner walls may also provide increased resistance to catastrophic damage in the event of an impact (e.g. the inner wall may remain intact).

An emergency vessel towing system includes a vessel attachment system, a retrieving system, and a towing line. The vessel attachment system is configured to connect to a vessel at sea, and includes a bridle system and a hawser line. The bridle system is operatively connected to the hawser line's proximal end. The bridle system is configured to engage at least four fittings on a foredeck of the vessel to distribute the load over the foredeck. The retrieving system includes a retrieving line with a proximal end that is detachably connected to the hawser line's distal end in a setup position. The towing line is detachably connected to the hawser line's distal end in a towing position.

The vessel attachment system is configured to connect to a vessel at sea, and includes a bridle system and a hawser line. The bridle system is operatively connected to the hawser line's proximal end. The bridle system is configured to engage fittings on two sides of a foredeck of the vessel to distribute the load over the foredeck. The retrieving system includes a retrieving line with a proximal end that is detachably connected to the hawser line's distal end in a setup position. The towing line is detachably connected to the hawser line's distal end in a towing position.
