1985 The Journal of Japan Institute of Navigation  
It is we11 known that, when a ship is under way in heavy seas , large amplitude of the ship motions occurs consecutively a few times as we 夏 l as large wave groups . In this paper , the number of consecutive Iarge roll and pitch amplitude was discussed , by using the motion records of the previous report . The following results were obtained . ( 1 ) The distribution of the number of consecutive large alnplitude can be calculate by the random theory. However , the observed values of the mean
