I already posted a story about my most recent dive onto the Henry Daryaw:
Here is the one part of that dive that went exceptionally well.
When briefing us on the Daryaw, the boat captain mentioned that the wreck is upside-down, and that the covers to the holds have been removed. So you can swim under the wreck, and some people swim up into the holds.
It seems that there is a huge air pocket in there, growing every time divers swim under the wreck with open circuit scuba. Their exhaust gas goes up into the hold and the air pocket grows a little bit more. It seems divers have great fun swimming up to the air pocket and shouting at each other.
Only--the captain warns us--don't actually breathe the stuff. No kidding. (I'm not suggesting the captain encouraged us to penetrate the wreck, BTW, just that he was describing the wreck and mentioned what people do when penetrating it).
Mr. Doubles and Pisces look at each other, then say they'd like to swim into the hold. I look at my gear again, just in case my single steelie has mutated into a pair of doubles. No luck there. My flashlight hasn't mutated into a canister light, it's still mighty useful for signalling someone or peering at a fish in a crack, but I wouldn't trust my life to it in an overhead environment without backup illumination.
And I have a wimpy little spool for my SMB, but I'm pretty sure it would snap like a spider's thread if laid into a steel wreck with sharp edges. Speaking of sharp edges, I'm diving a White's Fusion, it is basically a garbage bag with Lycra wrapped around it. I don't have the upgraded "tech skin" for protection against tearing it in a wreck and springing a serious leak.
But I don't want to spoil the party, so I tell my companions:
If you guys want to go into the hold together, I'll wait at the entrance for a minute or so shining my light at you. But if you go out of my sight, I'm returning to the surface without you.
They shrug and agree to skip the penetration, even though it's "easy" and "tons of people do it on singles." Considering what transpired later, I think I'm happy this "near miss" happened during the briefing.
...Let me tell you about the afternoon charter. There was supposed to be a lesson of some kind run by the charter shop, but it got cancelled leaving myself and two other walk-ons as the only people on the trip. Thus, we're diving as a group of three. Hmmm number one.
One of the other guys is diving dry and doubles, with experience diving the St. Lawrence and Atlantic Canada. He sounded solid, but he had a video camera, which is another hmmm. I will call him "Mr. Doubles."
The other guy announces that he's a fish lover not a wreck lover, so "don't be surprised if I stop to watch a fish and ignore the wreck." Ok, that's not a hmm, but I must admit I envy his subcutaneous insulation: he's diving a short pants, no hood, no gloves. The water is 70F, but this is the first time I've seen anyone that comfortable in it. He's obviously as comfortable as a fish, so I will call him "Pisces." That, and every diving story needs a Bond-type character with a trick nickname...
