The author is investigating consequent motion sickness of a 60 feet long motor yacht passengers. It is well known that the natural frequencies of rolling and pitching motions of motor yachts are higher than those of ocean going cruise ships. At present, it is not feasible to estimate the probability of motion sickness for small ships like motor yachts at the initial design stage. The estimation formula presented in this paper is composed with vertical acceleration and lateral acceleration, and the frequencies and amplitudes of accelerations are also taken into account. The results of estimation by this formula is compared to the results of questionnaire to passengers which consists of three-choice questions on feeling of motion sickness. We can mention that the results of this method agree with the questionnaire well.
