Zusammenfassung:PURPOSE:To provide an automatic steering gear for an energy saving ship by utilizing drift angle or even drift speed of the ship for controlling variable to control steering angle. CONSTITUTION:Since this steering gear carries out feedback control so as to reduce angular valocity r of bow turning and drift angle B or drift speed v, inertia resistance item (mo+my) U.B.r can be reduced, and since orientation deviation is controlled, high performance course maintaining property can be displayed similarly to prior autopilot so that fuel consumption required for voyage can be substantially reduced by reducing thrust resistance loss during voyage of the ship.
