We tried to determine Victory ship ' s minima1 . time route between Nozimazaki off and San Francisco off in winter . For this p1 ユrpose , we 皿 ade a wave model chart of North Pacific Ocean ln winter as the stationary wave field , and the loss of ship speed in waves was calculated by James ' empirical equations relating Victory − type ship , s speed to wave height and direction .
