Boat maneuvering system

1. A boat maneuvering system comprising:
- a target boat speed selector that sets a target boat speed of a boat;
an actual boat speed detector that detects an actual boat speed of the boat;
a throttle actuator that changes a throttle opening degree of a propulsion device;
a shift actuator that switches a shift state of the propulsion device;
a shift position detector that detects a shift position of the propulsion device;
a throttle opening degree detector that detects the throttle opening degree of the propulsion device; and
an actuator controller configured or programmed to control the throttle actuator and the shift actuator such that the actual boat speed reaches the target boat speed;
whereinthe actuator controller is configured or programmed to perform intermittent control of switching the shift state alternately to a shift-in state and a neutral state by the shift actuator when the throttle opening degree of the propulsion device is an idling opening degree in the shift-in state and a state in which the actual boat speed is larger than the target boat speed is generated and continually detected for a first period of time or more in an auto cruise mode of automatically controlling a boat speed.

Abstract
A boat maneuvering system includes an actuator controller that performs intermittent control of switching a shift state alternately to a shift-in state and a neutral state by a shift actuator when a throttle opening degree of a propulsion device is an idling opening degree in the shift-in state and a detected actual boat speed is larger than a target boat speed for a first period of time or more in an auto cruise mode.
