Recently, tankers and ore-carriers have a tendency to become larger and wider, however, we scarcely find any data of a series test on manoeuvrability of these ships. In order to investigate the effect of L/B upon manoeuvrability of the wide beam ships, a series of manoeuvring test on three tanker models, L/B of which were 4.0, 5.0 and 6.0, was carried out. The tanker of 5.0 in L/B is regarded as the mother ship. The effects of rudder form and its area ratio upon manoeuvrability of the mother ship model were also investigated. As the results of the series test, it is made clear that the course stability of these ships is so unstable one that has never been seen before, although the turning ability is still better. In order to examine the causes of unstableness in course stability, stream lines near the stern were observed on some models in circulating water channel. A series test on manoeuvrability of the ship models with the modified sterns were also carried out.
