"In the preceding report, the authors treated of the operational limitations during scouting work, on the basis of the characteristics of ship motion, by using an actual 135 GT purse seiner working in the fishing ground. In the present paper, the main objective was shifted to the same problem during a cycle of shooting and hauling work of the net. In order to examine this problem, the process of a cycle of fishing work was classified into the six steps, and the ship motions and accelerations were measured under the four sea conditions. From the results of spectrum analysis and statistical analysis of double amplitudes relating to rolling, the probability of deck-edge immersion was estimated, and the discussion was concentrated to the change in safety with progress of fishing work under respective sea conditions. And the discussion was extended to the safety of the crew on deck during fishing work."
