If the boat was not sinking, would it not have been better for them to stay on the boat, inside the cabin, waiting for it to settle down on the bar?
Hindsight is 20/20. Probably if they actually understood what the conditions where on the bar, they would have been willing to wait for days on the open ocean. I would imagine most boaters figure there will be a few minutes of excitement, then they will be home...
So then, how do you differentiate between what looks like it might be a wild ride, and something that is really dangerous?
