In the “Action Preventing Collisions at Sea”, regardless of the type of ship, the size of the ship, and the maneuverability, the timing of “Risk of collision” is defined as “a certain point”. In addition to navigating the ship according to the navigation law, the operators take actions to avoid collisions in consideration of weather, sea conditions, ship traffic congestion, water area, and own ship maneuverability.
On the other hand, in the Japan Marine Accident Inquiry, the date of the collision is traced back to determine the timing of “Risk of collision” and the navigation law is determined. However, when we meet on each other between a low-speed small vessel and a high-speed large vessel, there is a difference in the timing of “Risk of collision”. In particular, collisions between engaged in fishing vessels and general power driven vessels have occurred constantly.
In this study, for fishermen and pilot trainee, (1) when they feel a “Risk of collision”, (2) differences in avoidance action, and (3) applicable navigation with “Risk of collision” against engaged in fishing that do not display lights and shapes; Results of questionnaire survey focusing on the above three points, It was possible to point out the problems of the current law that are different from the events in the field.
