Dropped Rebelay

Postby lostgravity » Jan 18, 2013 4:23 pm

Hi,

Every now and then I run into situations where the only spot to fix an anchor for a rebelay is not where I actually want the rebelay... but I can set an anchor maybe 2 meters higher or some such... Anybody sees any issues with doing the following, or has better ideas?

Cheers,
David

Hi David.
I don't see any difference safety-wise using this type of configuration. I'm having a little trouble envisioning circumstances where you need the rebelay to be several feet (or meters) below your anchor. I guess if you had a rub spot between the rebelay anchor and a dropped rebelay knot you could put a rope protector above the knot and avoid having to deal with it when going up or down the rope.

Have fun in China!

Are you using a bowline to tie-off the rebelay? I'm not sure how to tie a bowline in the middle of a rope, and I'm not sure a bowline on a bight works in this situation.

Also, it's good you copyrighted this diagram. I'd hate to see others profit from your idea. :big grin:

I have seen exactly this done, and it works well.

I was wondering the same... I also would be concerned about the bowline being loaded incorrectly if somebody clipped the loop, instead of the designated clip-in point. Remember, people will do things wrongly. There is a long discussion over double bowlines and the safety hazard related to clipping them at rebelays over on the UKCaving forum. Perhaps a different knot would be more suitable?

You oughta come caving with us in Texas and I'll show you. ;-)

One occasion is an entrance drop where you have to squeeze past a windmill pipe in order to do the rebelay, and there is more room to do this comfortably two meters below the actual rigging point. And then I ran into a similar situation where it came in handy in the same cave. It probably could all be rigged differently without this workaround, but since there are existing anchors... :)

No, I'm not, just not paying attention when drawing the diagram. It's a butterfly. Although, technically, I guess you could use a bowline on a bight, but that'd be stupid. Fixing the diagram now...

*lol* I don't think the idea is original. The diagram is. Whateva. ;-)
