Abstract: Greatest difficulties on determining the collision avoidance manoeuvre in restricted visibility lies in the 'ambiguity' of other vessels action. Navigators are not quite sure whether other vessel is fully aware of the collision danger which exists between both vessel, and take suitable action. Moreover, information errors due to the performance charactor of radar bring about much difference in the recognition of encounter situation, leading them to various manoeuvres. To surmount these difficulties, authors made proposals to devide the situation into three stages according to the relative bearing and the range of other vessel, and allot the prime responsibility for manoeuvre in each stage. They contrived a manoeuvre to make conspicous change in apparent motion of own ship on radarscope, which seems to be effective to reduce the 'ambiguity' of manoeuvre.
