Earlier this week, Viking River Cruises announced that one of its ships struck a bridge Sunday while sailing the Rhine-Main-Danube Canal in Germany:
"Viking Freya experienced an accident in Erlangen, Germany early Sunday morning. Viking Freya’s wheelhouse collided with the bridge in Erlangen. Two crew members of the ship were in the wheelhouse and died as a result of injuries sustained during the collision. No other crew members or guests were injured, and all guests have been transported to local hotels..."
The above photo (click to view larger version) shows the top deck of another Viking ship with the wheelhouse in the "up" position. For low bridge clearances, the wheel house lowers inside the ship. Also, the crew lowers all railings on the top deck, and passengers are prohibited from that area. The photo on the left shows lowered handrails and a partially lowered wheelhouse.
The Metro UK reported (with photos) that the ship struck the bridge about 1:30 AM. The two crew members killed were from Hungary. None of the 181 passengers were injured. All passengers and 49 crew members were transferred to local hotels. Passengers were able to board another Viking ship in Passau, Germany to continue their journey to Budapest. While the Viking Freya is out of service for repairs, the Viking Bestia ship will substitute for future 2016 sailings.
During my Viking cruise in September 2014 from Amsterdam to Budapest, I noticed that there wasn't much clearance under some bridges; perhaps 5 to 7 feet between the top deck and the bottom of several bridges. See the photo below.
