Verification of a Wavemaking Resistance Reduction Method by Baba.

A series of resistance and longitudinal wavecut experiments were performed on Model 5079 (AKA 113) to verify a theoretical-empirical method developed by Baba for minimizing wave resistance by adding an optimum thin ship to an existing ship. The results indicate that the model developed using Baba's method shows lower resistance than the original model above the optimization speed but greater resistance below the optimization speed. A further improvement of Baba's method is necessary to obtain a balanced reduction in the resistance in the speed range of interest. (Author)
