Abstract: There is a present need for precise allweather navigation for surface vessels in harbors and harbor-approach areas. Even in Ambrose Channel, New York, 2 000 feet wide and thoroughly provided with lighted buoys and ranges, "there are still periods of low visibility during which deep sea ships cannot be piloted into or out of port with safety."’ It is unnecessary to point out that considerable financial loss ensues from such delays, not only in the waste of ships’ time, but also in the wages of waiting longshoremen and port officials. During war, time itself becomes a valuable commodity, while awaiting entry into a port might well prove fatal. If steering in thick weather could be made sufficiently precise, a system of traffic control would become practicable, making possible an appreciable increase in traffic density and permitting maximum use of the port in all weathers.
