Abstract
A ship maneuvering system includes first and second propulsion devices, a shift actuator, and a controller. The shift actuator switches a shift state of each of the propulsion devices. The controller causes the shift actuator of one of the first and second propulsion devices to execute intermittent control during low-speed navigation of the ship. The intermittent control intermittently switches the shift state to a shift-in state and a shift-out state.
Claims18
A ship maneuvering system comprising:
- a plurality of propulsion devices including a first propulsion device and a second propulsion device;
- a shift actuator to switch a shift state of each of the plurality of propulsion devices;
- and
- a controller configured or programmed to:
- cause the shift actuator to execute intermittent control to intermittently switch the shift state to a shift-in state and a shift-out state;
- and
- cause the shift actuator of one of the first propulsion device and the second propulsion device to execute the intermittent control during navigation of a ship at or below a predetermined speed.
A ship maneuvering method executed by a controller to maneuver a ship including a plurality of propulsion devices, the method comprising:
- causing a shift actuator to switch a shift state of each of the plurality of propulsion devices;
- causing the shift actuator to execute intermittent control to intermittently switch the shift state to a shift-in state and a shift-out state;
- and
- causing the shift actuator of one of a first propulsion device and a second propulsion device to execute the intermittent control during navigation of the ship at or below a predetermined speed;
- wherein
- the plurality of propulsion devices include the first propulsion device and the second propulsion device.
