THE PROBABILITY OF CLOSE OVERTAKING IN FOG

Mariners' judgment of minimum safe overtaking distance (MSOD) in fog varies considerably from person to person. Many are prepared to pass too close and are unaware of the risk they are taking. Others are overcautious and leave more sea-room than is necessary. This paper compares calculated values of MSOD in fog with the distances at which subjects in a radar simulator were prepared to overtake. The results are analysed, firstly to help the mariner and those responsible for his education so that the dangers may be better understood and thereby avoided, and secondly to assist the marine traffic engineer responsible for the planning of separation schemes which need to be designed to accommodate over taking.
