Switzerland's Viking River Cruises is expanding its fleet further with another order in Germany.

The Torstein Hagen-chaired company has contracted seven new river ships that will debut in 2019, the Neptun Werft shipyard said, without revealing a price.

Six of the vessels are Viking Longships for operation on the Rhine, Main and Danube Rivers, while the other is inspired by the Longships and specifically designed for Portugal’s Douro River.
