概要

In this paper, first we have derived two kinds of the equations of the sway, yaw and roll motions in waves based on the strip theory. One is according to the Ordinary Strip Method and the other according to the New Strip Method. In the next place, we have measured these three motions for a model ship with full form self-propelling in short crested waves generated in our long towing tank, and compared the results of computation by the above two equations with the results of experiments. Through the above study, it is concluded that the computed values from the equation of motion by the Ordinary Strip Method differ very little from the ones by the New Strip Method. Comparisons between computed values and experimental ones show satisfactory agreement for the amplitudes of the sway and yaw. As for the amplitudes of the roll in the resonance condition, however, the computed values are larger than the experimental ones by about 10〜20 percents.
