This is every recreational diver’s nightmare, surfacing to find no boat where one is supposed to be. And this guy was equipped with at least a whistle, but no one on the dive boat heard it. I remember when we first started diving and I insisted on whistles for the ex-wife and me, and she was like, Why? And I said, How long do you think you can scream for help before your vocal cords wear out? I hope the Coast Guard takes some serious actions against the captain and dive master on that boat; they deserve to be left alone in a tiny raft in the middle of the ocean for a day or two.
