The consortium comprised Compagnie Maritime Belge (CMB), Charles Hill of Bristol, England (owners of the Bristol City Line) and Clarke Traffic Services Ltd from Montreal, Quebec, Canada.
[1] The company operated between Antwerp and Southampton in Europe and Halifax, New York and Norfolk in North America.
[2] The purpose-built vessels operated by the consortium included the 31,036-ton MV Dart America, owned by Clarke and launched in 1970, and her sister ship MV Dart Atlantic, owned by Bristol City Line and launched in 1971.
Bibby later sold its share in Dart Containerline to Orient Overseas Container Line, which took over the Clarke shareholding in 1973.
In Canada, the successors are Orient Overseas Container Line, which eventually shed the Manchester Liners name, and Hapag-Lloyd, which took over CP Ships in 2007.
