using 2 ropes is fine for contingency..
Just tie your bend in the ropes below the rapide.
The last guy down has to remove the block.

o.k. I'll bite, you said a scenario for "you" meaning, me.
You told me the rap is 65'ish, even without knowing this distance, I would throw down approximately what I figured is enough rope, set a dynamic block.
If the first person get's into trouble 30' or so from the bottom, no problem,lower. If said person get's into trouble above 30'ish. No problem, start to lower and pass your knot(bend) when it get's to the rapide.
Now are you going to ask me how to pass a knot on a lower? :lol8:
I wouldn't be needing to pass the knot, I have a way I would do it if I had to but since it's ugly outside and nothing else to do but work if you would like to enlighten us let's hear it.
Mark
Yep. Depends on whether the belayer is following the pitch or not.Quote:

There's a few variations on that theme. Standard type especially multi pitch climbing, the belayer becomes the follower up a pitch and cleans the gear. Once at the top of a route, if there's not a convenient way off, then they rig for rappels off the anchor they used on the way up, or, they build anchors for rappels on the way down (at this point it kinda looks like canyoneering).
Very uncommon to see climbers rappel on anything but a doubled rope. Also common to see climbers, especially on half pitch routes, lower from the anchor.
Back to being lowered...I kinda hate it. I'd much rather rappel. I get lowered in the climbing gym all the time and I still never really get that comfy with it. Maybe I have control issues! Ha ha.

My bet is a pick off is faster and more efficient than rigging a haul for someone stuck on a rope. I can't imagine hauling someone back up to an anchor who's hair was stuck in their rappel device, especially given some terrain considerations. And, rigging off what anchor? A stack of rocks with a sling sticking out of the sand? Also, the haulee couldn't do much to guide themselves away from any features (their hands would be fairly tied up). A pick off would be fast and might solve the problem much faster and the rappeller may just continue on their way.Quote:

From here there are two ways I know how to due it. 1. Either take the extra bit of prussic cord and tie a munter/mule connecting it to the webbing. Start feeding the rope again, it is taken up by the prussic. Release the original contingency then release the prussic contingency. Once released the contingency on the rope behind the knot will take it up. Remove prussic, and lower.
2. Rig a mariner hitch going from the prussic up to the webbing. Feed rope through, it will be taken up by the prussic. Release original contingency. Release mariner, weight will now be put on our contingency behind the knot. Release prussic, lower. Neither of these has your buddy relying on a prussic alone.
I assume they are just rappeling double because it's easy to rig and go and very seldom do they have problems rappeling.Quote:

Thanks
The one's I see usually use a leg wrap.Quote:

I honestly think lowering off a contingency will solve 95% of CP canyon dilemma's regarding being stuck on rope. If we throw in water, it definitely changes things, as does whether the victim can help or is even conscience. Too many scenario's to be able to write one solution for sure.Quote:

I would do pretty much the same but a little different. If it was an emergency I would rig rope behind knot with a munter on a different webbing or above the over hand knot with the rapide in it. I would then lower the original cont. onto the munter. Then I would either undo the rapide or just cut it out. Then lower on the munter.Quote:

Yeah, ATC type device. Almost exclusively. Except folks who use only a gri gri for single pitch stuff sports type climbing (although rare they wouldn't have an ATC too).Quote:

Very very rarely do climbers tie off to retrieve gear on rappel. If they do, they usually just use a leg wrap and in some cases might use a body wrap or tie off their rappel/belay device.
Edit to add: one of my main partners makes a point of loading up and stopping on his autoblock so climbers use that as a method to stop on rappel too. I'm convinced he mostly does it to show me that I should be using one too! Pretty funny. But, super effective and easy to stop and go.
Usually, there's enough friction with a fat single climbing rope that just locking off a rappel with the brake hand works fine for even extended periods of time.
This single rope rappelling thing that canyoneers use is pretty interesting. Its probably the single technique that twists climber's heads up a bit. And, when folks don't rig for contingency, then some of us fail to understand why rappel single at all, when you have plenty of fat rope available.
I guess I've harped on this enough, but...look at the number of accidents related to not being able to control a single rope rappel...could be the #1 cause of canyon accidents?
Anyhoo, advantages and disadvantages to both.

I like your idea. I'd wager its a bit faster than the options I presented, I'll give it some practice.Quote:

Does anyone have a technique to remove a biner block without placing your buddy on a rope grab of some sort? Without removing the rapide or using a knife?
Brian,
Just my thoughts on rappeling single. If we were rappeling double all the time we would need to haul more rope in case we had a problem. Unable to use the pull side for rescue etc?
Thanks for the climbing responses.

Psychologically, being lowered or hauled out of a bad situation is tough (but often necessary).
<aside>
Me and my buddy Roger were first responders to a pit rescue in TN once...some non-local guy had rapped 150' down a 300' waterfall pit (in-cave) and was unable to continue up or down. Since he'd been hanging there for awhile in 54
Are you counting a Prusik (or other friction hitch) as a "rope grab"?Quote:

I'm guessing your talking about removing the biner to lower?Quote:

Otherwise back to your biner block--seem's you need some type of grab. First you have to haul to release the biner from the rapide.
