Zeebrugge Disaster. The News From That Night.

Interesting that was found in a skip, shows how the news was reporting the incident within hours of the tragedy .
Second is a pretty poor animation but does sorta show what happened.

MS Herald of Free Enterprise was a roll-on/roll-off (RORO) ferry which capsized moments after leaving the Belgian port of Zeebrugge on the night of 6 March 1987, killing 193 passengers and crew.

The modern eight-deck car and passenger ferry, owned by Townsend Thoresen, had been designed for rapid loading and unloading on the competitive cross-channel route, and there were no watertight compartments. When the ship left harbour with her bow-door open, the sea immediately flooded the decks, and within minutes she was lying on her side in shallow water. Although the immediate cause of the sinking was found to be negligence by the assistant boatswain, who was asleep in his cabin when he should have been closing the bow-door, the official inquiry placed more blame on his supervisors and a general culture of poor communication in Townsend Thoresen.
