Abstract (en)
[origin: EP4177153A1] A marine propulsion system (102) includes a main propulsion device (1) configured to rotate in a right-left direction to change a direction of a thrust, an auxiliary propulsion device (2) including an electric motor configured to drive an auxiliary thruster (20) and configured to rotate in the right-left direction to change a direction of a thrust, and a controller (6) configured or programmed to perform a drift control to move a hull (101) under external forces including wind and water flow while maintaining an orientation (T1) of a bow (101a) of the hull at a target orientation by rotating the hull. The controller is configured or programmed to maintain the orientation of the bow at the target orientation by rotating the hull by driving the auxiliary thruster while stopping a main thruster (10) of the main propulsion device in the drift control.
