Last year I did a liveaboard trip in Australia with a couple friends, but the day before we did a day trip on a very large boat. I was quite surprised by that experience for a couple of reasons.
1. We were arbitrarily assigned to groups, and we all had to go through the same briefing. I swear they came close to repeating the entire OW course in that briefing. They told everyone how to do even the most basic skills. Many of the people in the group seemed quite attentive, indicating they needed it. I have never seen such a thorough and so extraordinarily basic briefing anywhere in my life. I assume their experiences in the past told them it was necessary.
2. I was almost the only one on the boat who had brought his own gear, and the few others that did were familiar patrons with gear almost identical to that supplied by the boat. When I set up my gear, a back plate and wing with long hose and bungeed alternate, I explained to the DM for our group that in an out of air emergency I would be donating the regulator in my mouth and taking the alternate hanging from my neck. She looked at me as if I were insane. "Why on Earth would you do that?" she asked. I showed her how my gear worked, and she shook her head in wonder. During the rest of the trip, pretty much every member of the crew dropped by during the surface intervals to look at my crazy gear configuration. They had obviously never seen or heard of anything like it. Now, I know my gear choice is in the strict minority world-wide, but I would have expected that at some time in their past, someone in a crew of dive professionals would have encountered it, even if only in an online forum.
