I called off a dive in La Paz Mex. last year. Strong current, rough surface conditions and my regulator was bleeding small amounts of air.
Everyone else on the boat went in. One ended up needing decompression stops and an extra air tank had to be taken down to them. Three more drifted a mile or more from the boat as we took care of the first individual. It took some looking to find them but we were successful and no one suffered any serious harm.
I did not hear a single person comment one way or the other about my reluctance to dive in those conditions. But on that same trip I overheard a guy pressuring his girlfriend to make a deep dive that she did not want to do. I stuck my nose in and advised her not to dive if she wasn’t comfortable. She made the dive anyway then later spent the rest of the trip mad at the boyfriend for pressuring her.
I agree that there should be more emphasis on training divers on when to call a dive and how to recognise and remedy the tendency among, mostly male divers, to be more macho than the next guy.
