If this is the incident I did hear about the reasons were that they were told that they didn't want the child on the boat to start with, the parents signed a release that they would be responsable for the kid. Also it was not a large boat and the crew was trying to keep the boat a float ant running. I think it was a crew of 3 . Plus anymore you try to help and you do some thing that causes more injury you get sued so damn if you do and damn if you don't.
If this is the one , the judge threw it out of court. And told them they had no leg to stand on it was an act of nature.
