Viking sun, which was involved in the most recent accident is currently being reviewed and expected to be back in service within a few days.
Passengers who chose to continue on with the modified itinerary were given a future cruise voucher worth the full value of their paid cruise fare.
(October 2, 1:52 p.m. EDT) -- Viking Sun has been involved in an accident, the fourth accident involving a Viking boat in the past month. No injuries were reported.
The river boat, operated by Viking Cruises, struck a metal pier at a quarry along the edge of the Rhine early yesterday morning.
"Viking Sun experienced a collision with a docking station on the Rhine, near Strasbourg," a Viking Cruises spokesman told Cruise Critic. "There were no injuries, but a full inspection of the ship afterward would have caused an unreasonable delay."
The crash caused a tear of nearly 10 feet in the boat's hull, according to the French paper L'Alsace.
Viking offered passengers a choice to either return home and receive a refund for the unused portion of their trip or continue on with a modified itinerary via bus and receive a future Viking cruise credit, Viking said. "Some passengers opted to return home, but a vast majority chose to continue with the modified itinerary," the spokesman added.
An investigation is underway to determine the cause of the accident.
Viking Forseti, which launched this year, was involved in three accidents in September. It ran into the back of another ship when the two were in a lock together, then had a second ship run into it. Forseti also damaged a power line near Forchcheim, Germany, when a crane used to move the ship's gangway got out of proper position and hit the overhead power line. No one was injured in any of the accidents.
