Denmark’s Maritime Authority says that the operations manual for the Bornholmstrafikken-owned, Austal-built ferry Villem Clausen did not provide the vessel’s master with sufficient information regarding safe speed in heavy weather. This contributed to the vessel slamming into ‘one or more waves’ at 33-35 knots on 11 January 2010, during a crossing from Ystad in Sweden to Rønne on the island of Bornholm.
Six passengers were thrown out of their seats and injured as was one crewmember when the vessel hit the waves. Upon arrival in Rønne, two of the six injured passengers had to be treated at the local hospital. The most severe injury was a broken hip.
The slamming caused severe indentations in the bow.
