When Someone Forgot to Close the Door and 193 People Died: The Herald of Free Enterprise Disaster

On March 6, 1987, the British ferry *Herald of Free Enterprise* capsized just moments after leaving the Belgian port of Zeebrugge, killing 193 people in what became one of the most preventable maritime disasters in modern history. What makes this tragedy particularly remarkable—in the darkest sense—is that the ship rolled over and sank in approximately ninety seconds because someone forgot to close the bow doors. Not "forgot" in some euphemistic sense where complex mechanical failures were at play. No, the assistant bosun, Mark Stanley, whose literal job it was to close the doors, had simply fallen asleep in his cabin. The ship departed with its bow doors wide open, like leaving your house with the front door swinging in a hurricane, except the house is floating and the hurricane is the English Channel. As the ferry picked up speed, thousands of tons of seawater poured onto the car deck. The vessel, now resembling a massive floating bathtub someone had forgotten to turn off, became catastrophically unstable. Within a minute and a half, it had rolled onto its side in shallow water just outside the harbor. The subsequent inquiry revealed a culture of casual negligence that would make a health and safety inspector weep. No one on the bridge could actually see if the bow doors were closed. There was no warning system. Officers had previously requested indicator lights for the bridge—a technology that had existed since roughly the invention of electricity—but management deemed it unnecessary. Several captains had sailed with the doors open before; they'd just been lucky enough not to capsize. The disaster led to sweeping changes in maritime safety regulations, proving once again that humanity's most reliable method of improvement is learning very expensive lessons the hard way.
