Ship handling for leaving and entering port is very difficult and dangerous because a mariner needs to operate many devices and the area is restricted by a lot of elements. The mariner must control own ship's motion in line with the planned course. But the skill levels of young officers are low for lack of experience. So it is too difficult for them to control the ship's motions when her speed is low. In this paper, we proposed a new system to evaluate the risk of collision or grounding in harbour. This system based on the idea of potential area of water (PAW) can show the risk of ship handling using objectively time to collision (TTC). According to the result of experiment with ship handling simulator, it is proved that this system is useful for not only risk assessment but also supporting information for controlling a ship's motions. Several important conclusions are drawn as follows : (1) The result of risk assessment shows the level of skill in ship handling of the mariners. There are a lot of differences in the difficult situation. (2) The effects of training for cadets can be evaluated by comparing the result of each experiment. (3) A safe navigation can be carried out if the mariners, especially the young officer who are short of experience made full use of the information supplied by this system.
