The 16th ITTC International Towing Tank Conference Resistance Committee made a proposal of cooperative experimental research program for ship resistance and flow around hull to construct standard data base. In Japan four organizations conducted experiments on the Wigley parabolic model in order to investigate the scale effect of ship resistance using geosim model lengths of 6 m, 4 m, 2.5 m, and 2m. The experiments were separately performed on the following items and cooperatively analyzed Resistance test Wave pattern analysis Wake survey Wave profile measurement and Pressure measurement on hull surface. Measurement of boundary layer around the hull was also performed. The report of the cooperative experiment was presented to the Resistance Committee of the 17th ITTC at Varna, Bulgaria, in September, 1983. This paper summarizes the report, extracting principal data of experiments in order to serve as a reference for the theoretical prediction of ship resistance.
