What happened to personal responsibility? If a certified diver is not qualified to take care of themselves, they ought to be beating on their instructor's door, if anywhere.
I agree. I lay in bed and dream of a world with more personal responsibility. Either I am getting old and crotchety or it is going the other way.
Now in the real world, I would never suggest a diver go with an DM that isn't watching out for their divers in Coz, unless I knew they watched everything themselves. I have met divers on the boat that needed a keeper. And it isn't a small percentage is it? Divers that dive once a year or haven't been in the water in a couple years or just go out of OW and are still a little clueless.
So what is the answer:
1. don't take their money and let them dive;
2. Take only divers from some hypothetical program that isn't rushing divers through training;
3. Post a sign,
your life is in your hands on this boat;
4. Make sure they are hydrated, just in case,
or;
5. provide additional service beyond 'guiding' the tour.
Absent facts to the contrary, could not one wildly speculate that the profile was not a good one and they were following the DM guide?
Of course I agree with you philosophically. And you would probably not agree with me when I tried to apply the theory of personal responsibility further.
