Abstract
A small boat includes engines mounted on a hull, a plurality of water jet propulsion units disposed on both sides of a longitudinal axis of the hull and driven by the engines, and a steering wheel arranged to change jet directions of the water jet propulsion units. The small boat further includes a steering angle sensor arranged to detect a rotational angle of the steering wheel, front and rear gravity sensors arranged to detect a turning state of the hull, and a control device to which the rotational angle and the turning state of the hull are inputted in order to control thrusts of the water jet propulsion units such that the turning state coincides with any one of a group of target steady turning radii corresponding to the rotational angle of the steering wheel. The small boat turns along the steady radius regardless of any water conditions.
