10 minutes isn't a long time. As long as the guy is floating face up in the life jacket. You really need to acess the situation. Hauling him up over the side of the boat if he had a broken back or broken neck wouldn't be the smart thing to do. Which begs the question....What would you need to do if you saw this happen ?

Then what is the right thing to do ?
Do you float him to the bank ?
Call 911 ?
Get the Coast Guard ?
