As a series of experiment for the motions of inshore fishing boat in waves, the seakeeping experiments were carried out varying speeds, heading angles and displacement of a actual boat. And these experiments were repeated for four different sea conditions. From these experiments, we obtained the following results. (1) The wave hights of a record and double amplitude of roll and pitch angles were found to follow nearly Rayleigh distribution. (2) The values of the bandwidth parameter, ε_s, obtained by spectral analysis, lies in the range ε_s=0.30 to ε_s=0.80 for roll angles and in the range ε_s=0.40 to ε_s=0.95 for pitch angles under various boat and sea condition. And the values of ε_s for these motions were found to increase as the speeds increase.
