The wave exciting force and moment for a ship advancing in regular waves have been calculated by the so-called ordinary strip method (O.S.M.) proposed by Prof. Watanabe and Prof. Tasai. Many comparisons between computed values obtained by O.S.M. and experimental data have shown fairly good agreement in case of a ship advancing in head seas. On the contrary, the computed values for oblique waves have been scarcely compared with experimental data from lack of the testing facilities available for measuring the wave exciting force and moment in oblique waves. In this paper, the experimental data of the wave exciting force and moment in oblique waves which were measured at the New Seakeeping Basin of Tokyo University are reported and compared with the theoretical values. The theoretical calculations were carried out by the two different methods, that is to say the ordinary strip method and S.T.F. method. Comparisons between the theoretical values themselves by these two methods are also made. In consequence of comparison between the experimental data and the computed values, the fairly good agreement for practical purpose was shown with respect to the five components of the wave exciting force and moment except the roll-moment.
