I acknowledge I am biased on this issue, but I would question the logic and rationality of a dive op that would be so regimented as to take an AOW diver with as few as nine open water dives, but would refuse to take an an OW diver who is current, active with several hundred of hours and more than a decade of dive experience, and has a computer dive log covering the past 7 years. I understand it is their boat, their rules, but for me, there is not a dive in the world that would be so important that I would take the AOW course just to do the dive. But, I am also mature enough to know my own capabilities, and would not to sign up for a dive where my experience level might make me the problem child on the dive boat. However, if the dive op said, "OK, come along, but you will have to use a private DM for the first dive", I would be happy to do that, and might actually prefer it to being paired with many of the AOW insta-buddies I have watched on dive boats. Frankly, after observing AOW divers I have seen over the past seven years, I often remind myself "An AOW huh!, I think I'll spend the course money on another 3-4 two tank dives."
