One of the causes of accidents at sea involving small boat is not enough lookout. However, there have been few studies on behavior of boat’s operator such as lookout and safety checks on boat.

This research had a purpose which was to compare the behaviors of beginner and expert operators when maneuvering a boat and to reveal the differences between them. We conducted a maneuvering experiment of the operator’s behavior on straight line and altering course on 14 operators. As a result, we found that there was no difference in the number and duration of gaze in straight line course, and expert operators had many gazing time and duration for the 5 seconds before altering course. Begginers were found to be able to lookout when maneuvering, but they cannot found the danger.

These results suggest that boat’s operator keep lookout with understanding of dangerous objects to accidents at sea and contribute to safety navigation.
