It is important to develop criteria for measuring the safety level of a collision avoidance manoeuvre. For any each manoeuvre these criteria should be able to quantify the minimum distance at which ships should pass each other. However, when two ships have a large difference in speed, such as an encounter between a jet foil and a conventional vessel, it is clear that the jet foil mariner's preference of a safe passing distance is very different from that of the mariner on the conventional vessel. The results of a questionnaire completed by 37 jet foil mariners and experimental studies on a ship handling simulator involving 7 mariners from 450 GT conventional vessel show that the mariner on the conventional vessel sought to achieve a larger passing distance than the mariner on the jet foil and that the passing distance sought for vessels meeting at a 90°angle of encounter was great than in any other situation. On the basis of these studies it is possible to propose safety criteria for ships navigating at high speed when making collision avoidance manoeuvres.
