French ferry workers occupying two ships in protest against job losses are said to have run amok - drinking the bar dry and causing criminal damage.
The Rodin and Berlioz, which operated under the MyFerryLink brand, have been occupied since the beginning of the month at Calais.
Strikers are angry with the proposed lease of the vessels to Danish operator DFDS.
A picture taken by British Scandinavian chief executive Paul Woodbury shows they have deployed evacuation slides and daubed graffiti on the side of the boats.
