Abstract: A controller for a marine propulsion device determines a route on which a single or a plurality of target spots are located. The controller controls the marine propulsion device such that a watercraft moves along the route. The controller obtains a position of the watercraft, and determines whether or not the watercraft has arrived at a destination. When it is determined that the watercraft has arrived at the destination, the controller controls the marine propulsion device in a fixed spot keeping mode to keep the watercraft located at the destination.

Abstract: A thruster system for improved steering and maneuverability of a marine vessel when operating at relatively low, or wakeless speeds, such as in the vicinity of docks, swimmers or other obstacles, or when trailering, beaching or mooring. The thruster system has a modularized design adapted to independently control separate motor/propeller units located at various positions on the vessel's hull. Each propeller of the modular thruster motor system has its own relatively small, electric motor and mounting bracket, permitting each motor to be separately mounted to a location on the hull of the marine vessel apart from other thruster motors. The thruster system is further enhanced by an electrical control system for controlling each modular thruster motor system of the thruster system. In some embodiments, a charging system is provided that permits each electrical control system to be separately charged from the marine vessel's main battery.

Abstract: A drive unit for propulsion and trim control of a marine vessel. The drive unit extends in use from the vessel along a vertical axis to a base plane normal to the vertical axis, and spanned by orthogonal longitudinal and lateral axes. The drive unit includes a first propulsion unit and a second propulsion unit arranged separated along the lateral axis and intersected by the base plane. The first propulsion unit and the second propulsion unit are jointly rotatable about the vertical axis, where the first propulsion unit and the second propulsion unit are individually rotatable about the lateral axis.

Abstract: A method of controlling propulsion of a marine vessel includes limiting user input authority over propulsion output by at least one propulsion device based on proximity measurements so as to maintain the marine vessel at least a buffer distance from any object, where in the buffer distance is a predefined distance around the marine vessel. After a user-generated instruction is received to suspend maintenance of the buffer distance and a user control input is received to move the marine vessel in the direction of the object, the at least one propulsion device is controlled based on the user control input such that the marine vessel approaches and impacts the object.

Abstract: An improvement for inboard motor boats has a rigid exhaust conduit, a miniature rudder, and a rudder control system. The rigid conduit is provided for conduction of combustion gases exhaust outside the hull and has an aft facing outlet. The miniature rudder is pivotably mounted on the rigid conduit relative the aft facing outlet whereby combustion gases exhaust past the rudder. The rudder control system has a user interface inside the boat and has a control mechanism pivoting the rudder in response to inputs to the user interface.

Abstract: Systems, methods, and devices for enhancing steering control of a personal watercraft. An electrically actuated device is coupled to the steering system of the personal watercraft and applies torque to the steering system. At least one sensor is positioned adjacent the steering system and generates operational data of the personal watercraft. At least one controller is coupled to the electrically actuated device and the at least one sensor, and is configured to determine a first torque to apply to the steering system based on the operational data responsive to a second torque being applied to the steering system. The at least one controller is further configured to operate the electrically actuated device to apply the first torque to the steering system for providing enhanced steering control of the personal watercraft, with the first torque being applied only by the electrically actuated device.
