Relating to the capsizing accidents of ships in the strong tidal current that varies its speed sharply behind an island etc., the possibilities and the conditions of capsizing of a ship advancing across such flow boundary are investigated by a calculation. The equations of motion are described on the horizontal and rolling motions, and are solved by an Euler's method, using the hydrodynamic forces obtained mainly from model tests. The calculated results are arranged in the form of the maximum rolling angle vs. various parameters for analysis. The followings are some of the main results found: (1) The hydrodynamic lateral force on the hull plays the most effective role for the rolling moment. (2) The capsizing can happen in the severest possible condition of the current and the ship.(3) The capsizing occurs in so short period that the steering can hardly recover it so far as the ship has already been in such condition.
