The property of wind turbulence which effect on the motion of ship was investigated at first in this paper. As the result, the distributions of deviation from mean wind speed and main wind direction could be assumed Gaussian. The R.M.S. and gust factor as the turbulence quantities on the open sea are respectively expressed at eq. (1) and eq. (4) which are the function of mean wind speed. In the harbour, although the wind turbulence is very different acording to the distance from the land or structures which located at weather side, the reduction ratio of mean wind speed and the ratio of turbulence quantities have general tendency which are expressed at Fig.8, Fig. 9 and Fig. 10 respectively. Effect of wind turbulence on ship's. motion was investigated by digital simulation using typical ship's model and conditions. As the result, the oscillations of yawing angle and rudder angle owing to wind turbulence are not negligible especially in harbour. But its variance depend wholly on the conditions of computation which are ship's model and loading conditions, wind speed, wind direction, etc..
