She sails on the Belfast–Birkenhead route on charter with her marginally newer sister ship the Mersey Viking.
The Belfast–Birkenhead route is invaluable to drivers, as it saves them driving through Scotland on poor single-carriageway roads and behind a great number of freight vehicles. In all, the total journey time on board the ship is 7 hours. The ship has several facilities on board such as restaurants, bars, shops and a cinema.
