This study is the pilot study for a researching method to reveal causes of maritime disaster related to human factors. The method was a questionnaire for frightening experiences of maritime incidents. The subjects were watch-keepers on board the vessels of Japanese domestic maritime transportation. There were 408 incident cases of 484 respondents, which included more experiences for a fishing boat than for any other obstacles, and watch-keepers on cargo vessels had more experiences. Many incidents occurred during midnight and early morning. The calculated ratio of experienced watch-keepers to all respondents was 0.0139 per day and estimated term of the incidents was 72 days. From these results show that probabilities of experienced watch-keeper for each vessel were more than 22 times per year. These probabilities were 476 times of the probability of an accident that were judged by Maritime Inquiry Agency. The results suggest that this researching method enables us to gather the large number of data on maritime incidents without their anxiety for legal responsibility and influences from it.
