Abstract
A controller receives a bow turning signal to turn a bow of a watercraft and a propulsion signal to move the watercraft forward or rearward. The controller controls left and right outboard motors under a first control when receiving the propulsion signal after receiving the bow turning signal in a composite in which the controller receives both the bow turning signal and the propulsion signal. The controller controls the left and right outboard motors and a steering actuator under a second control different from the first control when receiving the bow turning signal after receiving the propulsion signal in the composite operation.
Claims16
A system for controlling a watercraft, the system comprising:
- a left outboard motor on a port side of the watercraft;
- a right outboard motor on a starboard side of the watercraft;
- a steering actuator that changes rudder angles of the right and left outboard motors;
- and
- a controller communicating with the right and left outboard motors and the steering actuator;
- wherein
- the controller receives a bow turning signal and a propulsion signal, the bow turning signal causing a bow of the watercraft to turn, the propulsion signal causing the watercraft to move forward or rearward;
- the controller controls the right and left outboard motors under a first control when receiving the propulsion signal after receiving the bow turning signal in a composite operation in which the controller receives both the bow turning signal and the propulsion signal;
- and
- the controller controls the right and left outboard motors and the steering actuator under a second control when receiving the bow turning signal after receiving the propulsion signal in the composite operation, the second control being different from the first control.
A method of controlling a watercraft, the watercraft including a left outboard motor, a right outboard motor, and a steering actuator, the left outboard motor being disposed on a port side of the watercraft, the right outboard motor being disposed on a starboard side of the watercraft, the steering actuator changing rudder angles of the right and left outboard motors, the method comprising:
- receiving a bow turning signal and a propulsion signal, the bow turning signal causing a bow of the watercraft to turn and the propulsion signal causing the watercraft to move forward or rearward;
- controlling the right and left outboard motors under a first control when the propulsion signal is received after the bow turning signal is received in a composite operation in which both the bow turning signal and the propulsion signal are received;
- and
- controlling the right and left outboard motors and the steering actuator under a second control different from the first control when the bow turning signal is received after the propulsion signal is received in the composite operation.
