Norfolkline, which already connects Dunkirk and Dover, has introduced a new Italian-built vessel on the 20-hour crossing between Zeebrugge and Rosyth. It will sail in each direction three times a week, and offer a range of fares, including mini-breaks.

The company said that it was happy with the level of interest already being shown and was encouraged by the fact that it was being actively contacted by road transport companies. Norfolkline hopes that its policy of combining passengers and freight, in contrast to Superfast's reliance on the former, will ensure the route's viability.
