This paper presents a method to calculate ship turning motion taking the coupling effect due to heel into consideration for a ship which performs large heel in her turning motion. The turning motion is calculated being based upon the coupled equations of surge, sway, yaw and heel. For two kinds of roll-on/roll-off ships computations are made, and the computed results are compared with the results of model experiment which was carried out using 5.0m long and self-propelled models. Both the computed and the experimental results are in satisfactory agreement, and furthermore the computed results explain very well the speed effect on the turning ability, namely the reduction of the turning radius according to the increase of the ship speed. The major conclusions obtained in the study of this paper are that the turning motion of a ship with large heel, such as a roll-on/roll-off ship. should be treated together with the motion of heel simultaneously, and that the calculation method proposed here is effective and useful for the analysis of the turning motion of such a ship.
