Abstract: A ship designed to achieve high speed through the use of multiple, low wave-making resistance, submerged hullform pods is constructed for stable operation during maneuvers with and without a payload. Movable fins on the submerged hullform pods are constructed and are operable to provide the turning and to counteract an inertial moment produced by an elevated center of gravity of the ship so that the ship turns flat or rolls into a turn and does not roll out of a turn. A load balancing pod is movable fore-to-aft and side-to-side to balance the amount and the location of varied payloads on the ship. The movement of the fins may be a tilting movement, or each fin can be maintained at a set angle but extendable out of and retractable into a related pod to create the amount of side force needed for maneuvers and/or to control the amount of lift that might be needed during operation of the ship.

Abstract: An exhaust system for an outboard motor includes an internal combustion engine. An intermediate member supports the engine. A housing unit depends from the intermediate member. An exhaust system guides exhaust gases from the engine. The exhaust system includes a main exhaust passage and an idle exhaust passage. The main exhaust passage discharges the exhaust gases that are produced above idle to the body of water through the housing unit. The idle exhaust passage discharges the exhaust gases that are produced during idle to the atmosphere. The intermediate member defines a portion of the main exhaust passage and a portion of the idle exhaust passage. The intermediate member forms a recessed area in the main exhaust passage portion. The idle exhaust passage communicates with the main exhaust passage portion at the recessed area.

Abstract: A sailing craft that can transform from wind propulsion mode to flying mode, comprises a body and two sails or wings each pivotally connected to a common boom which is supported by a spar pivotally connected to the body. The dihedral angle between the wings can be varied by a system of adjustable stays between the masts and the upper and lower ends of the spar. In sailing mode, either wing can be tilted essentially upright and swung relative to the axis of the body to derive propulsion from the apparent wind whilst the other is essentially horizontal to develop counter balancing moments. In flying mode, both sails can be tilted essentially horizontal to derive lift from the apparent wind.

Abstract: An axial-flow outboard water jet propulsion unit is designed so that it does not extend below the bottom of the boat hull, but rather is disposed directly behind the hull transom. This is achieved by arranging the impeller shaft generally perpendicular to a generally vertical drive shaft, and by installing the impeller in a flow-through duct which, although placed directly behind the transom, has an inlet for taking in water located directly below the impeller shaft. The duct does not extend to a depth lower than the lowest point of the hull bottom. The impeller shaft penetrates the duct wall, while the impeller itself is rotatable inside the duct. The impeller impels water rearward toward a convergent exit nozzle of the duct, sucking in water through the duct intake. The aft opening of the exit nozzle forms the duct discharge outlet.

Abstract: An integrated or attached (built in or retrofitted) space occupying (fills space beneath the chin) cephalic restraint collar (holds the head in the axis of rotation) for improved personal flotation device (“PFD”) performance. The restraint assists with aligning and securing the head and neck in line with the axis of rotation. In this position the ballast of the head is divided evenly about the axis of rotation negating its ability to oppose effective rotation. The cephalo-cervical restraint improves the efficacy of all PFD designs elements targeting turning. By guiding the head into a cylindrical notch in the posterior cervical foam behind the victim's head the head is then aligned along the axis of rotation where the heads 14-17 pounds of ballast is symmetrically distributed about that axis.
