Marking a landmark year of innovation and expansion, Viking River Cruises christened the first four of its new Viking Longships yesterday (March 21) in Amsterdam. Rebecca Eaton, executive producer of the PBS series “Masterpiece” and Joanna Lumley (pictured), the British actress famous for her role as “Patsy Stone” on “Absolutely Fabulous,” joined the celebration as the ceremonial “godmothers” for the Viking Freya and Viking Odin. Renowned Harvard physicist Dr. Lisa Randall and Viking’s most travelled passenger, Gail Wiswedel, served as godmothers for Viking Idun and Viking Njord.
