This happend directly behind the boat I was on this afternoon. Unfortunately, this guy dove head first into the water and floated to the top. If it wasn't for his friend, he probably would have drowned. There were many people who came to his aid, it's too bad that he most likely will be paralyzed for the rest of his life if he survives.
If, god forbid, this happens to someone when you are on the water, please be sure not to move a person with a neck/back injury out of the water. I know your intentions may be good but you most likely will cause more damage. Keep them as stable as possible so not to cause any additional injury. Keep their head above water and immediately call for medical assistance.
As most of you are aware, your cell phones do not have the best signals out on the water. Please contact the Coast Guard via ship to shore radio and if at all possible give them your GPS coordinates so that emergency personnel can get there as soon as possible.
My thoughts and prayers go out to this guy.
