Abstract: A system is provided and includes a trim tab, a hinge assembly, an actuator, and a controller. The trim tab adjusts at least one of pitch, roll or yaw motion of a marine vessel while the trim tab is in a deployed state. The trim tab includes a member, which has first and second ends and curves outward between and forward of the first end and the second end in a direction away from a point rearward of the member. The hinge assembly attaches a rearmost end of the first trim tab to the marine vessel at a location rearward of the member. The member rotates about a portion of the hinge assembly. The actuator actuates the trim tab. The controller controls the actuator to transition the member of the trim tab between a retracted state and the deployed state to adjust an attitude or motion of the marine vessel.

Abstract: A jet propulsion system includes an inlet receiving a fluid, and a housing defining a discharge nozzle through which fluid is discharged to provide propulsion of a vehicle in a first direction. The jet propulsion system also includes a reverse mechanism movable between a deployed position redirecting fluid from the discharge nozzle toward the first direction and providing propulsion of the vehicle in a second direction substantially opposite the first direction and a non-deployed position allowing fluid to exit the discharge nozzle and provide propulsion of the vehicle in the first direction. The reverse mechanism produces a flow entrainment that enhances forward thrust while the reverse mechanism is in the non-deployed position which results in a net thrust gain over the thrust attributed to the discharge nozzle alone.
