The paper deals with model test techniques to estimate manoeuvring qualities of actual ships. Scale effect is an important problem in estimating the manoeuvring qualities of actual ships by model tests. To solve this difficult problem, two model test techniques are proposed; one is a free-running test technique with large models (length of models ≒ 15m), and the other is a captive model test technique with small models (1ength of models ≒ 3m). In the former, by using large enough models, and in the latter, by improving the technique, such as by choosing an adequate swaying or yawing frequency, we consider the problem of scale effect can be solved. From the fact that some manoeuvring characteristics estimated by these model test techniques agree well with those obtained from manoeuvring tests for some actual ships at sea, it is concluded that these techniques would be effective to solve the scale effect problem.
