Seasickness has always been a serious issue for people prone to motion sickness. Obviously if passenger comfort
could be improved, they would easily get on board much alike as getting in a car. The design of the
ride control system for a fishing vessel presents special problems due to the need to optimize the
arrangement of actuator. In addition, the effect of this system sometimes gives a different reputation
among the shipbuilder, ship-owner and fishermen. The main reason is that they do not have a common
long measure related to seasickness.
In this paper, a new evaluation method of the hde control system for a fishing vessel has been proposed from
the viewpoint of human engineering. The method evaluates the amplitude of accelerations, their frequencies and
the influence of exposure duration. The point about the development of this method takes into account the influence
of exposure duration during the boarding time. In the evaluation method, the effect of ride control system is
quantitatively discussed among the shipbuilder, ship-owner and fishermen.
