The length of experience as a navigator, such as year or a month, is one of important factors in collision judgments. In addition, collision investigations indicate that experience with ships of a specific type, such as specific ship's length or specific gross tonnage, is also important. In this study, we focused on experience with ships of a specific type and investigated the time of action taken based on sea experience using a questionnaire in several navigational situations involving a risk of collision. The results indicated the following. (1) Person with experience on a large vessel tend to make judgments earlier than those with experience on a small vessel. (2) Fisherman's judgments tend to differ from persons with other sea experience. (3) The navigator of a larger vessel tends to experience conflicts of judgment when the larger vessel is standing on and crossing with a smaller vessel. The results were discussed, and the need for further study and education based on human factors was pointed out.
