I wonder what other groups you prejudge? Would you not pick a woman? What about a minority, or an older person?
I trust no one but myself. When contemplating diving with one or more strangers on a dive boat, I'd prefer to dive alone and not place my safety or my own liability in the hands of an unknown diver, especially considering that the "average" diver (from what I understand) dives perhaps only a few times per year with long stretches in between, and many of them have never pursued additional or refresher training once they completed their OW certification. I do not prejudge and I am certainly not discriminating between women, minorities, or older folks, however I'll admit that given the choice I'd pass up the 90 year old geezer and buddy up with the hot 20 year old blonde in the tight fitting wet suit. In fact, given a choice between diving solo and pairing up with the blonde, I'd take my chances with her. Even if she put her mask on backwards.
Actually they are the words of the OP. You guys seem to be taking the same track and I mixed you up. My error.
When you read something someone else wrote, and then you choose to add a few of their words to your own posts without quoting them, they're your words too.
No one would argue that someone who is morbidly obese is not fit enough for diving.
There's another risk factor for morbidly obese divers that I have not seen mentioned in ANY reference material but I can speak from personal experience on this one, because I took a group trip once and there was a really large dude with us.
Every so often towards the end of the dive, someone would surface and jump on the poor guy, sending him sputtering and gasping below the surface. That in of itself is a panic trigger right there. Finally he got smart and stopped removing his mask and regulator even though the seas were dead calm, but the strange activity continued.
Upon questioning the divers who did this, they all said the same thing.
"We thought he was the BOAT!"
It gets worse...once we were right in the midst of starting a dive, some divers were already in the water, and we got an emergency broadcast from another boat, about a half mile away, warning of a rogue wave approaching the size of a Tsunami! Their boat was completely swamped and in danger of capsizing, and reports started to come rolling in from others in the area. We braced for impact, divers either descended or in a panic, scrambled back up the boarding ladder, and we secured our gear. But it never came, and here's why... in case you haven't yet guessed it...the wave was going away from us. Why? Because it was the result of big dude doing a giant stride off of
our boat.
