Abstract

A marine propulsion system includes a main propulsion device, an auxiliary propulsion device including an electric motor to drive an auxiliary thruster, and a controller configured or programmed to perform an automatic marine vessel maneuvering control to direct a bow or a stern of a hull to a target point by rotating the hull and maintain the hull, the bow or the stern of which has been directed to the target point, at the target point by moving the hull in a forward-rearward direction. The controller is configured or programmed to rotate the hull by driving the auxiliary thruster while stopping a main thruster of the main propulsion device in the automatic marine vessel maneuvering control.
