The previous paper, the first report, described a new method to calculate the hydrodynamic lateral forces acting on a ship during manoeuvring motions on the free surface. As an application of this method, the hydrodynamic lateral forces on a flat plate piercing the free surface were calculated, and it was found that the predicted values of linear stability derivatives were in good agreement with the experimental results. In this paper, the hydrodynamic lateral forces on a Wigley model, which is a substitute for a ship model with realistic hull form, are calculated and compared with experimental results obtained by the authors and Kashiwagi, independently. Although the present method is not completely satisfactory, it can predict well the effects of hull form, ship's foward speed and the frequency of manoeuvring motions on the linear stability derivatives. Hence, it is supposed that the present method may be valid for estimating the linear stability derivatives of a ship with more general hull form.
