No way you ever would consider going adrift here:

Here is what is going on downstream a little over a 1 mile.... regulatory has a real big issue with things adrift in a major shipping channel.

While I get your point, they did eventually bail from the line, and from what I see they were close to the surface anyway

And while I concede the point that heading to the surface in that location isn't the best and number one option, given the CF they were engaged in, it would have been the best option (given they were so close anyway).

Of course this whole thing needn't have become the drama that it did. It was nothing more than a minor inconvenience compounded into something greater by poor management of the situation.

I hope their take away was that their actual experience and capabilities fell far below the level they thought they were

I maintain that a (conventional) long hose would have been a hindrance in this circumstance, a 40" with a swivel would have been a much better option. I'm also a huge fan of the "English" config where the Alt 2nd (Octo) comes from teh left and is on a swivel as its much easier and more natural to donate.

Can you expand on your reasoning here? In my mind a long hose donate would have made it trivial for the group to have continued their ascent along the line side by side just as they were doing prior to the OOA. None of this facing each other or climbing over each other to donate.

Yes certainly.

A slightly longer hose would indeed have been an asset. However in this type of situation, in current there is the risk that if they lose contact, one person drifts out of reach. (I'm writing up an example of this exact issue which I'll put into a new thread soon)

On an Air share, especially with divers of this calibre it's imperative that physical contact is maintained at all times. So with physical contact, anything more than 40" is superfluous, and the excess could just be more than a hindrance - especially in this case.

Don't get me wrong, I use long hose for penetration dives. But for OW (unless I'm on a DPV along with my buddy) then a 40" is absolutely the perfect length to be able to share in comfort while maintaining control of the situation.

Just my opinion - although it does have some basis of prior experience

In response to the OP's original question, about 1-2 yrs ago I made a thread in this subforum about my SPG leak that might add some info

Luckily, my leak happened on the surface, but when it happened, there was such a big violent bubbling that I assumed that my tank must have completely emptied in the 1-2 minutes before I shut it down.

Once I got everything fixed, turns out I only lost about 200 psi.

So from my experience, even though not much air is involved in an HP hose leak, the bubbles sure are impressive. Maybe the fact that the air is exiting at HP makes the bubbles seem like they are more than they actually are.

That’s very useful to know: because I have never seen a SPG leak I was impressed by the amount of bubbles like you said

I just don't log dives
The air-2 wasn't long enough to donate.

Primary donate, the Air 2 is for the donor, that's why it's short.

The air-2 started free-flowing.

Breathing off a freeflowing reg is a pita, but doable, especially when there are bigger problems.

It would be stressful to go OOA on a line in that kind of current but I can't help but think that it would have been so much easier to deal with if they'd had a long hose, real octo, and better training.

I agree, but my emphasis would be on better training. Over the years I have dove with a double hose, a single second stage, a standard rec primary and alternate, primary and Air 2 clone, various lengths longhose and bungeed backup, and at no time have had an issue with sharing air, because I train with the rig I am using. It's not the configuration that is the problem, it's the skill of the diver.

I like that BSAC and DIR groups have a standard configuration and insist that members are proficient, unfortunately a lot of other divers not only have different configurations, but they don't stay proficient on their gear, if they ever were. Not that I'm jumping on board with a standard configuration, but training and demanding proficiency is a good thing, of course being demanding is one reason I wind up solo.

At least one of those divers would have rocketed uncontrolled to the surface if they attempted a free ascent. Listen close, and you can hear a BCD over pressure relief valve doing quite a bit of venting on the ascent, while holding the line to stay down.
