Patent attributes
A propulsion system on a marine vessel includes at least one steerable propulsion device and at least one lateral thruster. A steering wheel is operable by a user to steer the at least one propulsion device. A user interface device is operable by a user to provide at least a lateral thrust command to command lateral movement and a rotational thrust command to command rotational movement of the vessel. A controller is configured to determine a difference between a steering position of the propulsion device and a centered steering position. A user interface display is controllable to indicate at least one of the steering position of the propulsion device and the difference between the steering position and the centered steering position. The controller is further configured to determine that the steering position is within a threshold range of the centered steering position prior to enabling a joystick thrust control mode.
