A few years ago two people died in a similar accident right before a cold front presaging a storm moved in and snapped the line.

A 33-year old mom dies and one of her two young sons is in critical condition. They were involved in a horrific parasail accident where the cable snapped and the three of them were dragged through the water for about a mile. They hit the 7-Mile Bridge.

When he arrived at their location, he and his two passengers brought the woman and children aboard the boat.
One child, who was about 10 to 12 years old, was battered but conscious. The other child, who is around 7, was unconscious and wrapped in the parasail’s lines, Callion said. “It was pretty much the worst thing you could imagine,” he said. “It was real bad.”
Callion had to cut the harness to free the three from the chute, which was hung up on the old bridge.
