The author proposes a new resistance test method for high-speed crafts. Forces acting on a craft are measured by two load cells. Moment about a imaginary center of gravity and lift are calculated from the measured forces by a computer. The attitude of the craft in free towing test is estimated using these values, and the attitude of the craft is changed by stepping motors which are connected with the craft by rods. This procedure is repeated to satisfy the convergent conditions. The four or five runs are needed to converge. Two crafts are tested. As the results, resistances, mean sinkages, trim angles measured by the present method agree with ones in free towing test. The present method can deal with arbitrary towing position and direction.
