The line pioneered the regular passage of ocean-going vessels along the Manchester Ship Canal. Its main sphere of operation was the transatlantic shipping trade, but the company also operated services to the Mediterranean. All of the line`s vessels were registered in the Port of Manchester, and many were lost to enemy action during the First and Second World Wars.
