The new KEITEN-MARU made its maiden voyage across the Pacific Ocean from December, 1974 to March, 1975 and set out on the second ocean navigation to the Indian Ocean from April, 1975 to July, 1975. Between the two voyages we made investigation into the relation between the weather adjustment and direction of wind and waves and also the relation between the ship’s speed (3,7 and 12 knots) and yawing rate, while steering the ship with auto pilot. We got the following results: 1) The yawing angle is little influenced by the forces outside the ship in case of the weather adjustment under the dial at 1, 2 and 3. 2) The yawing rate is comparatively little when the forces outside the ship come on the bow and very large when the forces outside the ship come on the stern. 3) The yawing rate is reduced when the ship’s speed is increased and the forces outside the ship come on the bow. 4) The yawing rate increases very much when the ship is sailing at the half speed (7 knots) and the forces outside the ship come on the stern. 5) The steering error is large when the fbrces outside the ship are on the beam or stern 45 degree and also large when the ship’s speed is slow.}, pages = {65--71}, title = {(新)敬天丸のヨーイングについて}, volume = {24}, year = {} }
