Radarと航法(日本航海学会第15回講演会)

抄録

The present auther studied the relations between a power driven vessel fitted with Radar and the Rule of the Road at Sea, and reached the following conclusions. (1) There is a great difference between visual sighting and radar detection. (2) The speed of a radar-fitted vessel in fog, should be "moderate", and reasonable speed may be lower then this when ships sail in fog toward one another, diminihshing the time and space available for detecting. (3) Rule 16, (b) of the International Regulations for Preventing Collisions at Sea, which is concerned with the position of a vessel, may not safely be applied to positions determined by radar detecting.
