In this paper, the authors show the results of the safety assessment of the navigation through a narrow channel using a ship handling simulator. The authors had proposed safety levels and safety margins. The safety level is subjective condition or difficulty of navigation. The safety margin is the index of navigation safety and has many kinds. For example, it may be time, distance or countermeasures, etc. But the effective safety margin depends on navigation environment and own ship's characteristics. To obtain these indices, we held some simulator experiments. The Ondo channel, which is typical channel in Japan, was applied to these simulator experiments. First, with the experiment's results and the interview after each experiment, the authors clarified the methods of navigation through the channel and the matters that required attention. Through the method and the attended points, we clarified the safety levels and some safety margins.
