A method for controlling a marine vessel having first and second steering nozzles and first and second trim deflectors comprises generating at least a first set of actuator control signals and a second set of actuator control signals. The first set of actuator control signals is coupled to and controls the first and second steering nozzles, and the second set of actuator control signals is coupled to and controls the first and second trim deflectors. The acts of generating and coupling the first set of actuator control signals and the second set of actuator control signals result in inducing any of a net yawing force, a net rolling force, and a net trimming force to the marine vessel without inducing any other substantial forces to the marine vessel by controlling the first and second steering nozzles and the first and second trim deflectors. Also disclosed is a system for controlling a marine vessel.

A marine vessel maneuvering system includes a controller configured or programmed to perform a propulsion reverse direction control to change a direction of a propulsive force of a propulsion generator to a reverse direction when a user operates an operator to turn a marine vessel either counterclockwise or clockwise and the marine vessel has been previously turned either clockwise or counterclockwise, respectively.

The present disclosure generally relates to a joystick device (100) operable to provide speed, direction and steering commands for controlling a marine vessel (300), the joystick device (100) comprising a movable steering lever (102) extending on an axis (V) and adapted to be tilted from a neutral position in at least four directions including a forward, a rearward, a leftward, and a rightward direction, wherein—an active length of the movable steering lever (102) is adjustable between a first (L1) and a second (L2) lever length,—the first lever length (L1) is shorter than the second lever length (L2),—a first mode for operating the marine vessel (300) is associated with the first lever length (L1), and—a second mode for operating the marine vessel (300) is associated with the second lever length (L2), the second mode being different from the first mode for operating the marine vessel (300).

A lateral thruster is configured to generate starboard and port thrust to propel the marine vessel. A user input device is operable by a user to provide at least a lateral thrust command to command lateral movement of the marine vessel and a rotational thrust command to command rotational movement of the marine vessel. A controller is configured to control the parallel propulsion devices and the lateral thruster based on the lateral steering input and/or the rotational steering input and the drive angle so as to provide the lateral movement and/or the rotational movement.

A method of controlling a propulsion system on a marine vessel includes receiving proximity measurements describing locations of one or more objects with respect to the marine vessel, receiving a command vector instructing magnitude and direction for propulsion of the marine vessel with respect to a point of navigation for the marine vessel, and then determining a funnel boundary based on the command vector. When an object is determined to be within the funnel boundary, a propulsion adjustment command is calculated to move the marine vessel such that the object is no longer in the funnel boundary. At least one propulsion device is then controlled based on the propulsion adjustment command.

A system for controlling a marine vessel having first and second steering nozzles and corresponding first and second reversing buckets, comprises a processor configured to receive a first vessel control signal including at least a component corresponding to a translational thrust command in a port direction, and that is configured to provide a set of actuator control signals coupled to and control the first and second reversing buckets.
