In the previous paper, the rsults of the series tests on the manoeuvrability of the huge tanker models, L/B of which were 4.0, 5.0 and 6.0 respectively, were reported. The estimation of the course stabilitty of the actual ships was difficult from the results, because the r'-δ curves showed the unusual characteristics in the range of small rudder angles. Using the models with modified sterns so as to suppress the above mentioned chara-cteristics, the series tests were carried out again. From the results, it was made clear that the unusual characteristics disappeared by the modification and the estimation of the course stability of the actual ships became possible by the model tests. In addition, some investigations were made on the effects of the rudder area ratio and its aspect ratio, the control method of the driving motor upon the manoeuvrability and also on the causes of scattering of the r'-δ curves in the range of small rudder angle.
