操船方略の経験による違い

Abstract

Cadets often do not handle the ship properly during onboard training on the ship Fukae maru of Kobe University. There are two reasons why cadets could not completely avoid other ships. First, the cadets cannot recognize the risk of collision ; second, they cannot form and execute a ship-handling strategy. Many studies focus on recognizing collision risk, but there are no studies on ship-handling strategy. The ship-handling strategy was examined using papers that presented navigation situations. Participants are students in a navigation course and experienced men who are masters or navigation officers of merchant vessels. The results indicate that the strategy differs by experience, and that students' strategies were generally not acceptable. Results also suggest differences in how other ships are considered and what action is to be taken. Differences of ship-handling strategy based on experience were discussed.
