Abstract
A steering method for a boat with a marine propulsion unit at the stern is provided in which a reaction torque is applied to a steering wheel in response to external force to the boat. The steering method includes: detecting a steering angle and the behavior of the boat; determining whether or not the turning of the steering wheel is in an initial phase based on the detected steering angle and the behavior of the boat; and applying the reaction torque to the steering wheel in response to the determination.
