The ship left her berth in Zeebrugge inner harbour at 18:05 (GMT) with a crew of 80 and carrying 459 passengers, 81 cars, three buses and 47 trucks. She passed the outer mole at 18:24 (GMT) and capsized about four minutes later. When the ferry reached 90 seconds after leaving the harbour, water began to enter the car deck in large quantities. The resulting free surface effect destroyed her stability. In a matter of seconds, the ship began to list 30 degrees to port. The ship briefly righted herself before listing to port once more, this time capsizing. The entire event took place within 90 seconds. The water quickly reached the ship's electrical systems, destroying both main and emergency power and leaving the ship in darkness. The ship ended up on her side half-submerged in shallow water from the shore. Only a fortuitous turn to starboard in her last moments, and then capsizing on a sandbar, prevented the ship from sinking entirely in much deeper water.
