MS Hamburg is a 15,000-ton, 420 passenger, luxury cruise ship owned by the Conti Group and is now operated by Plantours Kreuzfahrten. She was built in 1997, in Wismar, Germany. Her relative small size allows her to transit the Great Lakes in North America, where she cruised seasonally between 1997 and 2011, as well as other cruises worldwide as travelling the Mediterranean for cultural cruises with Martin Randall Travel, the north Atlantic and at Asia. Her crew consists of 170 members, and her top speed is 16 knots. She was previously known as Columbus for Hapag-Lloyd, she was since replaced by Columbus 2.
