Abstract: The present invention is broadly directed to an unmanned surface vessel (USV) 10 broadly comprising: 1. a vessel body (12) adapted to contain a payload (14); 2. a front fin (16) and a rear fin (18) connected to and protruding from the vessel body (12); 3. a forward foil (20) and a rearward foil (22) connected to a distal end region of the respective front and rear fins (16) and (18); 4. propulsion means (24) operatively coupled to the rear fin (18) for propulsion of the fin (18) and the foil (22) through the water.

Abstract: The present invention is directed broadly to an underwater appendage assembly (10) of a marine vessel (12). The underwater appendage assembly (10) is in the form of a rudder assembly fitted to a bow section (14) of the vessel (12). The rudder assembly comprises an appendage in the form of a rudder foil (18) connected to a flapper member (20). The flapper member (20) is arranged whereby movement and more particularly pitching, of the vessel (12) induces deflection of the flapper member (20) relative to the rudder foil (18). This deflection in the flapper member (20) provides an oscillating movement of the flapper member (20) in a flapping action which is substantially synchronised with movement of the vessel (12) upward and downward. The flapping action of the flapper member (20) is effective in promoting forward propulsion of the vessel (12).

The cable or rope (18) is at its distal end attached to a remote device (20) with the cable or rope (18) arranged to cooperate with the winch (16) to be deployed and retrieved from the vessel (10) via operation of the winch (16). The underwater appendage is in the form of a keel including a cavity (22) designed to partly locate the winch (16).

Abstract: The present invention is directed broadly to a marine vessel (10) comprising a deck (12) mounted to a hull (14) together with a sail (16) coupled to the marine vessel (10) via a mast base assembly (18). The mast base assembly (18) comprises a mast tilt assembly (22). The mast base assembly (18) also comprises a mast base mounting (20) to which the mast tilt assembly (22) is pivotally mounted for movement about a tilt axis (24) between stowed and operative positions. The mast base assembly (18) further comprises a sail slew assembly (26) mounted to the sail (16) associated with the marine vessel (10). The sail slew assembly (26) is operatively coupled to the mast tilt assembly (22) for slewing of the sail (16). The sail (16) is rotated or slewed about a slew axis (28) of the mast tilt assembly (22) to reorient the sail (16) relative to the marine vessel (10).

Abstract: The present invention relates broadly to a rigid wing (10) which in its preferred embodiment is a rigid wing sail fitted to a water-borne vessel. The rigid wing sail (10) comprises a pair of elongate rigid panels (12A) and (12B), and a hinge element designated generally as (14) coupled to the panels (12/B) to permit pivotal movement of the panels (12A/B) relative to one another. Each of the pair of panels such as (12A) includes an adjoining edge (16A) and an opposing lateral edge (18A). The hinge element (14) is coupled to the panels (12A/B) at the respective adjoining edges (16A/B) to form either: 1) a closed configuration of the wing (10) with lateral edges (18A/B) of respective panels (12A/B) positioned adjacent one another wherein the rigid wing sail (10) is closed; or 2) an open configuration of the wing (10) with the lateral edges (18A/B) of the respective panels (12A/B) separated from one another wherein the rigid wing sail (10) is set at a variable camber.

Abstract: A pivoting sailing rig adapted for use on a vehicle, such as a watercraft, includes a frame with spaced apart primary shafts which are oriented to rotate about and move axially along axes which are generally parallel to the center line or fore-aft axis of the watercraft. Wing sails are mounted on coupling elements secured to the primary shafts and are connected to rigging for rotating the wing sails about their longitudinal axes to vary the angle of attack, respectively. The primary shafts include control arms and rigging for rotating the primary shafts between substantially upright positions of the wing sails and laterally declined and reefed positions of the wing sails. The wing sails may include solar collectors mounted thereon and may be oriented in use to take advantage of wind as well as sunlight conditions to optimize sailing as well as energy collection.
