In view of the great importance of securing correct and factual knowledge regarding the sea-performance data of an actual ship, as the foundation of methods to investigate the sea-going qualities of vessels, the Experiment Tank Committee of Japan had been planning for several years to carry out systematic actual ship experiments on the sea-worthiness of vessels. Actual preparations were finally completed in 1951,and the experiments were conducted on a cargo ship, S.S. "Nissei Maru", with the support of many Japanese organizations in the field of marine transportation and shipbuilding. The experiments occupied a period of 129 days, from 26th December, 1951,to 3rd May, 1952 on the ship's maiden voyage from Yokohama to Vancouver, Honolulu, Singapore, Bombay, Mormugao, Shingapore and back to Yokohama, a distance of 21,700 nautical miles. The members of the committee boarded the vessel, andthe ship's speed, revolutions per minute of the propeller, the torque of the intermediate shaft (SHP), the helm angle, the yawing angle, the pitching angle, the rolling angle, the heaving of the ship and the stresses of the hull in several positions, as well as the wind and sea conditions, were measured or observed by them simultaneously. The total measurements recorded amounted to 154,and much interes ting and instructive data and experience were obtained.
