Abstract
A marine propulsion system includes a controller configured or programmed to perform a control to rotate a hull by driving an auxiliary propulsion device having a maximum output smaller than a maximum output of a main propulsion device and having a steering angle range wider than a steering angle range of the main propulsion device without generating a thrust from the main propulsion device.
Claims18
A marine propulsion system comprising:
- a main propulsion device to be attached to a stern of a hull and operable to rotate in a right-left direction to change a direction of a thrust;
- an auxiliary propulsion device to be attached to the stern, including an electric motor to drive an auxiliary thruster to generate a thrust, operable to rotate in the right-left direction to change a direction of the thrust, having a maximum output smaller than a maximum output of the main propulsion device, and having a steering angle range wider than a steering angle range of the main propulsion device;
- and
- a controller configured or programmed to perform a control to rotate the hull by driving the auxiliary propulsion device without generating the thrust from the main propulsion device;
- wherein
- the controller is configured or programmed to perform a control to rotate the hull by driving the auxiliary propulsion device without generating the thrust from the main propulsion device and with a rudder angle of the main propulsion device changed to a same side in the right-left direction as a rudder angle of the auxiliary propulsion device.
