An investigation was carried out at DTNSRDC to compare the trends in resistance for similar hull forms between large and small size models. Resistance experiments were conducted with three similar twin screw hull forms having a moderately fine shape Block coefficient 0.59. The results of these experiments are presented. The resistance trends obtained with the large and small models show good correlation. However, the full scale resistance predictions with the small and large size models did not compare as well.
