If you do a touristy-type dive at Ginnie (like I would do) I don't really see a big upside in diving sidemount or a twinset... what difference does it make? Do you think it's less safe to do a dive like this in SM?
I dive side mount in caves more out of necessity. I've had seven operations on my right hand (I accidentally told someone today it was 13, but that was wrong), two on the left and Achilles Tendon surgeries on both ankles. Toting both LP120s on my back from my van down the stairs and into the water just won't cut it for me anymore. Even one at a time, I would like to dial that back a bit in weight, so today I picked up my new SF2 rebreather. Yay me.
What I've noticed is that this phenomenon doesn't happen in real life
Yet, that's exactly where the scenario I posted happened: IRL. Denigrating the internet or people on the internet is just as bad as denigrating your fellow diver. I've seen you FIGJAM people here, so it's not just the newbies that have this problem.
Huh? Isn't Frank one of the more vocal opponents of sidemount?
You know, I don't think Frank likes SM, but he was pretty clear it was my choice: not his. He gave me a set of requirements, like being able to negotiate his ladder and left it to my discretion. He mentioned earlier how I loved diving off of boats in the Sea of Cortez and he failed to mention that those were all RIB dives. You had to hand up your BC or your tanks, and I was amazed at how much easier it was for me to dive SM on a RIB than it would have been for BM. Why? Because it was. However, I've only attempted side mount on Keys style dive boat a few times. Two with HP80s, four with AL80s and a few sidemounting a GEM. I don't like it and I see no need to continue to try to dive that kind of set up off of Burpees and Newtons. I might have been excited about how nice diving SM on a RIB is, but I didn't make the Back Mounters feel they had to justify their decisions either. I see it as an easy way to double my gas supply when I'm diving abroad and can't bring my steels. Dive and let dive.
Sure, Frank was the first person I heard "Where's your sidemount?" from on that trip, but he wasn't the only one. Frank's best attribute is that he's brutally frank. That might be his worst attribute too. All I know is that I feel he runs the safest liveaboard in the world. All of the liveaboards I have been on have been quite safe, so don't read anything negative in that about them. But no other boat captains sweat the details like Frank and Melanie do to keep us safe. Safe is fun. I like Frank's boat because I like how Frank and Melanie run it.
