I just want to know what happened after the Capt said no.... did they sit out the dive ?

No they dive, and they learn quickly how in the real world one protocal really doesnt suit all situations

and at the last minute before rolling blow off the 2nd stage bottle for ease of movement.

?? What does this mean?

God i am going to be embarrassed if its obvious

Yes I had a bit of a debate with the DIR boys about ascending shot lines / deco lines. I loved the bloke who said if i was diving a stream lined rig I would be able to hold position with some relaxed finning

that cracked me up.

Two said if they HAD to ascend the shot they would refuse to dive?? Interesting as these two are booked to dive Mullen Head in September with none other than JJ himself on board Loyal Watcher.

I believe two of the big signature wrecks out there are shot line ascent only

.

I cant wait for the trip report.

I imagine he means that they only jumped in with one stage cylinder - instead of the 2 that DIR would advocate for such a dive?

That's how I read it too.

Too funny.

That's almost as funny as the NE charter boat captain that was down here in FL spouting off how we don't have current as bad as they do "up there" and dictated that the boat be anchored into a deep wreck. Then he sees the Sargassum whipping by and says, "gee, I guess youze guyz do get current down here!"

It would seem many people don't really know how to judge true current or know what you can and can't do -- as evident by the "we dive in 7 kt currents all the time" (and being able to pull down an anchor line in 7 kts) statements on the internet.

3 kts doesn't sound fast sitting in front of a computer, but its a whole other world in the water.

OK ---

Back gas, intermediate deco gas, oxygen.

Planned dive to carry them all. A quick look at surface conditions and currents and at the last minute we decide to forget the O2, and just carry one bottle for ease of movement when tieing in. The dive will be cut back a bit and the deco schedule switched to just back gas and intermediate gas for the deco.

Doing a tie in sometimes just means plain work. The tie in team sacrafices a dive so others have a good tie in. We pick up the longer dive on the tie-out.

I find doing tie-ins on OC so much easier than on CCR.

Cheers

Pierre-

We don't use a "shot line" per se- but rather a grapnel hook with a length of chain. THe combination of the grapnel and chain gives enough weight that the line drops quickly, and the grapnel hooks into the wreck pretty easily. The first team on the bottom checks the grapnel and makes sure it is secure, and the last team off the wreck pulls and fouls the hook.

How do you get over the problem of having to ascend the first 10m quickly to avoid rehooking the wreck?

We use the same method in the UK to hook the wreck and then reel off and back to the anchor, last team brings up the hook but I am a bit worried about Hyperoxia on ascent due to the fast first 10
