It is considered that the most important factor causing "a man overboad accident" from a fishing vessel is the ship motions, particularly the accelerations. From this point of view, the authors have been studying human dynamic responses to the ship motions. This paper describes experiments performed by the authors on human dynamic responses to the ship motions, on the degree of mental and physical fatigue in long-term navigation. The results of the experiments are as follows. 1) A period keeping human posture on ships consciously is nearly one minute. 2) The maintenance of human posture on X-direction (front-to-back) is hard to conrtol in comparison with Y or Z-direction. 3) The response amplitude characteristics of human responses to the ship motions on Y and Z-directions are approximately equal to 1, and on X-direction is given as linear function for all ω between 0.9 and 1.5.
