A vessel heels inward toward the center of a turning circle about her fore and aft longitudinal axis immediately after her rudder is put over, and then heels to the opposite side, as shown in Figs.1 and 9. The maximum heel angle φ_<max> is significant to the safety of the vessel. In the previous paper, we reported on the turning motions of fishing vessels covering the various lengths and displacements shown in Table 1. The mathematical model which describes the motion of the manoeuvring vessel is based upon the coupled equations of surge, sway, yaw and heel. Then, the computed results of the time histories of heel angle for each vessel were obtained at the same time as shown in Figs.2-7. They are compared with the results of the full scale trial in Fig.8. In addition, considerations on the variations in heel angle in accordance with the changes of metacentric height and trim are presented in this paper.
