  • Patent number: 11685492
    Abstract: Embodiments of the present invention are directed to devices adapted to enhance propulsion (i.e., propulsion enhancing devices) of watercraft such as, for example, personal watercraft and the like. To this end, a propulsion enhancing device in accordance with the disclosures made herein may be attached to or integral with (e.g., formed unitarily with a housing thereof) a propulsion unit of a watercraft. The propulsion unit generates a stream of water that provides for propulsion of the watercraft.

  • Patent number: 11675372
    Abstract: A method of controlling attitude of a marine vessel includes identifying a natural roll frequency of the marine vessel, measuring a roll motion of the marine vessel with an attitude sensor, and then determining that the roll motion exceeds the threshold roll where no corresponding steering input is present. The method further includes determining a counteracting drive movement for at least one propulsion device based on the measured roll motion and the natural roll frequency of the marine vessel. A steering actuator is then controlled to move the at least one propulsion device to effectuate the counteracting drive movement so as to counteract an environmentally-induced roll motion of the marine vessel.

  • Patent number: 11673634
    Abstract: Disclosed herein is an inflatable watercraft barrier in one example having an inflatable perimeter tube. Also disclosed is a diaphragm sealed to the perimeter tube to form the watercraft barrier between a watercraft and the water in which the watercraft barrier and watercraft float. In one example, a portion of the perimeter tube forms a gate portion which is at least partially selectively deflated so as to be denser than water, and therefore rotates about a gate pivot such that the watercraft may enter the watercraft barrier through the gate portion. Also disclosed is a water pump in fluid communication with the watercraft barrier so as to evacuate water from between the watercraft barrier and the watercraft.

  • Patent number: 11667367
    Abstract: A marine muffler capable of handling both marine engine exhaust gas and marine engine cooling water includes a double wall baffle partitioning the muffler interior so as to function as a cooling water conduit. The cooling water conduit includes an inlet disposed external to the main muffler housing and an outlet configured and disposed so as to discharge the engine cooling water into the exhaust duct connected to the muffler outlet. The muffler is thus able to convey the engine cooling water through the muffler housing within a dedicated conduit while maintaining the cooling water separate from the exhaust gas. A muffler that is adapted to handle both the exhaust and cooling water flowing from a marine engine allows for the elimination of engine cooling water piping.

  • Patent number: 11655008
    Abstract: A trimaran which includes a self-righting structure positioned near the stern that substantially raises the center of buoyancy. The trimarans two peripheral hulls are shorter than the main hull and positioned near the one end to create an unstable inverted environment wherein when inverted the vessel rests primarily on the self-righting structure and an end of the main hull, substantially raising the center of gravity and creating an unstable configuration. This causes a pitch or roll about the vessel's longitudinal axis, which continues until the vessel has returned to its more stable upright position resting on three hulls.
