The recent collisions in the English Channel and the Dover Strait have caused a great deal of public disquiet in this country and the United Kingdom's Department of Trade and Industry's Safety of Navigation Committee were invited to discuss what, if any, measures should be recommended to Imco to improve the routing system in the Strait. The Institute of Navigation, with its French and German counterparts, was largely responsible for the introduction of the routing scheme in force in the Strait and has since its introduction in 1967, by means of a series of international working groups, kept a watchful eye on how things were going, and on occasions made recommendations for its improvement.
