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 vessel includes an actuator having a function of generating a propulsive force of a vessel and a function of generating a moment of the vessel and a vessel control device that operates the actuator, wherein the vessel control device can perform automatic cruise control and fixed-point holding control of the vessel and includes a fixed-point holding target position setting unit that sets a fixed-point holding target position that is a target position of the vessel where the fixed-point holding control of the vessel is to be performed, and when the vessel control device performs automatic cruise control of the vessel and then performs fixed-point holding control of the vessel, the fixed-point holding target position setting unit sets a position different from an automatic cruise stop position that is a position of the vessel where the automatic cruise control of the vessel is stopped as the fixed-point holding target position.
