I usually don't dive deep enough for need of a bottle, but just out of curiousity, why don't you allow bottles on the line?

For open water boat dives we take the gas we need for the dive with us since we can't guarantee that we will be able to get back to the hanging bottle.
Hanging a bottle sets the divers up psychologically to consider that as part of their gas resource and thus can influence decision making.
That is my reasoning.

I agree with UP, hang bottles can influence in the wrong way. If something does go wrong your safety should be on your back (doubles or pony). Whose to say you can make it back to the line if you need that hang bottle? What if you're diving a 400' wreck and you need to ascend 100' from the line on your own bag and reel? If you have your own supply you can do that. If you rely on a hang bottle, you take unnecessary risks to get to that line and that bottle.

I just can't buy into this philosophy U.P.
You can plan to take "all the gas you'll need for the dive" & still come up short if Murphy gets into the mix & mucks about. For all the effort it takes to hang a bottle, I see it as just one more way to make things a little safer.
As to generating wrong thinking? I don't get it. If you carry all the gas you'll need & dive your plan, all should be ducky & you'll never have a lost gas / low gas issue - right? However, if your plan goes for a crap because that substance can infect the best laid plans of the best of us, well then a hang bottle might just prove useful.
Those who can't get the hang bottle concept as being a resource for emergency use only should take up a non-self contained dependent sport, I reckon.
Best,

There are those that just fore see it all...and those that dont. The second group just needs to be more prepared...and the first sometimes a little more humble.

...I can "forsee it all" is the day I hang up the fins, pitch a tent, shine up the crystal ball & hang out my "open for business" sign!
10 years in the commercial deep seas & 10 years helping John Q. Public out of situations I wouldn't of believed possible has convinced me that the only certainty is uncertainty.
D.S.D.
There is one thing that is certain... if you don't have a hang tank, you can't get back to it. For some, perhaps there is comfort in that certainty.
Me, I've been known to hang a tank from time to time over the past thirty-five years. It's never part of the gas plan and we've never had to use one. However, using one to save the gas in deco bottles for another dive ain't such a bad idea, is it?

I would not plan for a hang bottle to be there. I can certainly see its benefits. But given the nature of people, it can be dangerous. How many people do you know that push the limits, procrastinate to the last possible second, manage their finances consistently on the edge? Now imagine Murphy putting four of these people on one boat. (Four people with catastrophic brain failure.) They all suck their tanks down and head up knowing that they have some backup gas available. (AND they're hoovers too!) Imagine the shock on the face of the fourth person when he (oh, no couldn't be a she 
) ascends to find three people already SHARING the hang bottle.....OR how about the first person that "NEEDED" it already took it up with them to the boat.
Maybe if no one is told that there will be a hang bottle there, then none of the Murphy proteges would plan on riding the edge to use it. So throw one in after everyone has descended and if someone comes up with Murphy on their back they can be pleasantly surprised. Otherwise, forget it. People will plan to use just because they want a 'little more' bottomtime.

It can be dangerous only if it falls off and hits you in the head. To each his own...if divers actually think it's there for gas management, they have no business diving and I would also fault the person in charge for not explaining its purpose. Are there stupid divers? Of course. Just don't penalize a diver who actually may need it for an EMERGENCY.
