This report deals with discriminations of critical conditions of a high speed ship in following and quartering sea waves. A discriminating method is proposed based upon Lewison and Paulling theory and the sofware tools for the Sea State Determinations by using image information data transmitted from the Geostationary Meteorological Satellite (GMS). A series of numerical computations are executed for a long liner, a trawler, a container ship and a 100 meters high speed ship for a sea state in the North Pacific Ocean within a winter day by using the proposed discriminating method. It is shown that those ships usually encounter a congregation of quartering waves and the high speed ship particularly encounters critical conditions in quartering waves near beam seas. It is confirmed that the method is useful for discriminating the critical ship's course in quartering ocean waves from hour to hour.
