Cruiseferry
A cruiseferry is a ship that combines the features of a cruise ship with a Ro-Pax ferry. Many passengers travel with the ships for the cruise experience, staying only a few hours at the destination port or not leaving the ship at all, while others use the ships as means of transportation.
Cruiseferry traffic is mainly concentrated in the seas of Northern Europe, especially the Baltic Sea and the North Sea. However, similar ships traffic across the English Channel as well as the Irish Sea, Mediterranean and even on the North Atlantic. Cruiseferries also operate from India, China and Australia.
