摘要：
It is common to evaluate the course-keeping quality of a ship with the use of spiral test results. But, in real situations, the spiral test is very difficult to execute, and moreover, time consuming. Therefore, if there are some alternative methods to treat the course-keeping quality of a ship, those are quite preferable in the practical fields. In this paper Zig-Zag tests and overshoot angles are simulated for various patterns of spiral curves with hysterisis loops. Also, the relations between overshoot angles and the course-keeping qualities are discussed.
