Abstract
A marine propulsion system includes a controller configured or programmed to perform a control to move a hull in a lateral direction by driving both a main propulsion device and an auxiliary propulsion device having a maximum output smaller than a maximum output of the main propulsion device.
Claims16
A marine propulsion system comprising:
- a main propulsion device attached to a stern of a hull and operable to rotate in a right-left direction about a first steering shaft located a first distance rearward of the stern to change a direction of a thrust;
- an auxiliary propulsion device 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 about a second steering shaft located a second distance rearward of the stern greater than the first distance to change a direction of the thrust, and having a maximum output smaller than a maximum output of the main propulsion device;
- and
- a controller configured or programmed to perform a control to move the hull in a lateral direction by driving both the main propulsion device and the auxiliary propulsion device;
- wherein
- the main propulsion device is provided on a centerline of the hull in the right-left direction;
- and
- the auxiliary propulsion device is provided to one side of the centerline of the hull in the right-left direction.
