The Dover Harbour Board is the responsible authority for the running of the Port of Dover. The English Channel, here at its narrowest point in the Straits of Dover, is the busiest shipping lane in the world. Ferries crossing between here and the Continent have to negotiate their way through the constant stream of shipping crossing their path. The "Dover Strait Traffic Separation Scheme" allots ships separate lanes when passing through the Strait. The Scheme is controlled by the Channel Navigation Information Service based at Maritime Rescue Co-ordination Centre Dover. MRCC Dover is also charged with co-ordination of civil maritime search and rescue within these waters.
