Abstract: A watercraft maneuvering system includes an actuator having a function of generating a propulsion force of a watercraft and a function of causing the watercraft to generate a moment, an operation unit configured to receive an input operation of a watercraft operator, and a watercraft control device configured to operate the actuator. When the operation unit has received an input operation for stopping an operation of the actuator while the watercraft control device is operating the actuator, the watercraft control device operates the actuator without any need for the operation unit to receive the input operation for at least one function of the actuator generating the propulsion force in an opposite direction to a direction of an inertial force occurring in the watercraft and causing the watercraft to generate the moment in an opposite direction to a direction of a moment of inertia occurring in the watercraft.

Abstract: A remote watercraft maneuvering system includes a watercraft and an input device. The watercraft includes an actuator having a function of generating a propulsion force of the watercraft and a function of causing the watercraft to generate a moment, a manipulation unit, a watercraft control device, a watercraft position detection unit, and a communication unit. The input device includes a communication unit, an input device position detection unit, a manipulation unit, and a notification unit. The watercraft control device has a normal watercraft maneuvering mode and a remote watercraft maneuvering mode. In the remote watercraft maneuvering mode, the communication unit of the watercraft receives information indicating the position of the input device from the input device, the watercraft control device calculates a distance between the input device and the watercraft, and the communication unit of the watercraft transmits information indicating that the distance between the input device and the watercraft is greater than or equal to a threshold value to the input device and the notification unit provides a notification for a remote watercraft maneuverer using the input device when the distance between the input device and the watercraft is greater than or equal to the threshold value. The threshold value is smaller than a maximum value of the distance between the input device and the watercraft when communication between the communication unit of the input device and the communication unit of the watercraft is possible.
