A ship steering device includes a handle which is mechanically separated from a rudder mechanism, a steering angle detecting unit that detects a steering angle of the handle, a rudder motor that drives the rudder mechanism, and a turn controller that controls, based on a steering characteristics map which associates a basic relation between the steering angle and a turn angle, the rudder motor so as to obtain the turn angle in accordance with the steering angle. The steering characteristics map has a characteristic such that, in a second steering region where the steering angle is larger than the steering angle in a first steering region, a change amount of the turn angle relative to the steering angle is large with respect to the first steering region where the steering angle is set from zero in advance.
