It is required that the ship preserves the environment in the marine transportation. In this meaning, recently, the necessity of the sail equipped motor ship has been increasingly recognized. However, there is a problem that the equipped sail brings poor maneuverability of the ship. To improve the maneuverability, five kinds of the following automatic sail control modes were developed. (1) Ahead moving control, (2) Turning control, (3) "Heave to" control, (4) Astern moving control, and (5) Side moving control. The maneuvering simulator with the two dimension display which incorporated these control modes was developed. The ability to control of the five kinds of the control modes in pure sailing under the constant wind was discussed in the preceding report. In this paper, the ability to control of the ahead moving control mode and the turning control mode with the engine assist under the change wind is discussed. The simulation results show some improvement in the ship maneuverability of the sail equipped motor ship with the automatic sail control modes. It is found that the sail shaft rotating speed is required to be more than 5 deg/sec.
