The European river cruise line Viking just launched four new ships in Amsterdam. They will sail along the Rhine, Main and Danube.

Viking calls them Longships, because among the 250 cabins will be larger and more luxurious suites. Passengers who book them will be sailing in two-room apartments with extensive balconies for viewing the passing European scenery. Ancient Norse Viking sailing vessels that explored as far west as America were called longships.
