With a ship model of a Series 60, C_B=0.70 parent form, resistance and self-propulsion tests, wake measurements at the position of propeller disc in regular head waves and overloaded self-propulsion tests in still water were carried out in the Experiment Tank of Osaka University. From the results of these experiments, the self-propulsion factors in waves were investigated, and it was shown that the self-propulsion factors in waves vary with the wave length, especially with in the range of λ/L〓1.0∼1.5, and are not always identical with those in still water. The experimental results of ship motion and resistance increase in waves were compared with the results obtained from the theoretical computations.
