The authors have been studying the seakeeping qualities of a fishing boat with those of a radio controlled fishing boat model in Lake Ohnuma. Generally speaking, the motions of a ship in irregular waves, like wind waves, can be determined by a linear superposition of the ship response to the individual regular wave component. It can be considered that the same principle exists in the wind waves at Lake Ohnuma. In this paper, concerning the frequency response characteristics of a fishing boat to the waves, the results that were calculated by the Ordinary Strip Method were compared with the results that were obtained by the Towing Tank experiment of the Fishing Boat Laboratory Production Division of Fisheries Agency. According to these results, the response characteristics of a salmon steel fishing boat to the longitudinal waves were calculated by the Ordinary Strip Method and shown in Figs.3 and 4 On the other hand, in the above experiments, the wave heights and ship's motions in head sea were measured and recorded. The statistical analysis was applied to these data and the wave and ship's motions spectra were obtained and shown in Figs.5 and 6 According to the above mentioned theory, the authors compared and calculated the spectra from the frequency response characteristics with some given measured spectra and discussed about them.
