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 watercraft control system includes a watercraft and a communication device. The communication device includes a communication unit configured to transmit information indicating a location of the communication device to the watercraft. The watercraft includes a communication unit configured to receive the information indicating the location of the communication device and a difference calculation unit configured to calculate a difference between the location of the communication device and a location of the watercraft.

Abstract: This outboard motor control device controls a plurality of outboard motors disposed on a rear portion of a hull of a boat. Each of the outboard motors includes a propulsion unit and a steering actuator. A boat includes an operation unit configured to operate the steering actuator and the propulsion unit. The operation unit is able to be positioned at a first position where the outboard motors do not generate a propulsion force of the boat and a second position where the outboard motors generate a propulsion force for moving the boat in a left-right direction. When the operation unit is moved from the first position to the second position and maintained at the second position, the outboard motors generate a first propulsion force during a first period from a first timing when the operation unit is moved to the second position to a second timing and subsequently generate a second propulsion force greater than the first propulsion force during a second period after the second timing.
