Two teenagers tried to pass a closed bascule bridge with a 26-meter-long ship. It was apparently not their first act: they are said to have previously targeted another boat.

The ship collided with a dolphin – a pole rammed into the bottom of the harbor – of the bridge. The traditional ship suffered damage to the rudder blade as well as to the bow and stern areas. The two teenagers are suspected of having previously boarded a sailboat that drifted abandoned in the harbor basin.
