The author researched into collisions caused by inadequate look out, making the database based on ananlysis of 666 cases and tried to draw fault tree charts. Findings of this research are as follows. (1) The fault tree charts are available for the prevention of this kind of collisions. (2) Many of the cases include small fishing boats or other vessels smaller than 500 gross ton with a single man watch. (3) The reasons of inadequate look out seem to be carelessness, fatigue, lack of sleep, being absorbed in other work or one direction, and being at the blind spot. Therefore it is indispensable to keep watch physiological condition in good shape in order to avoid human errors. And, it is important to inspire his awareness of watch and to clear the blind spot. If these are improved, 70 percent of collisions will be avoided.
