On 27 October 1991, Hurricane Grace battered the entire Eastern Atlantic Seaboard. As 95 mph winds drove massive swells onto shore, hundreds of homes and businesses were damaged or destroyed, while 400 miles offshore, a sword-fishing boat named the Andrea Gail was heading home with a hold full of fish. She was about to be hit by the storm of the century; the mighty north-easter of 1991, when Hurricane Grace collided with a cold front from Canada and a storm from the Great Lakes. Sometime in the middle of the night on 28 October, the Andrea Gail found herself at the centre of that so-called 'Perfect Storm'. She was never seen again.
