Knotless Prussic/Nacrabiner

Won't work.

While your loading one end of the bury, you're releasing the other end. On a ucr type bury you have to load only
one end. Any tension on the other end, even a little, and it releases the constrictor.

I just got it too. Cool idea!

Ah ok. What if it didn't have the loop, (the continuous one all the way around) but instead had an eye splice on one end for tarp connection, so that the pull was only on one side?

[Mundele]

Or you could still have the nacrabiner but you'd have to put a tie-loop close to the bury then leave enough slack so that the other end of the bury wasn't being released.

Gonna have to play with it some I think.

Yep, that will work. Need to play with bury lengths to see what holds. You could also larks head the fixed eye right to your tarp and then run your bury.

IMO, at some point you overcome the simplicity of the prusik. I think this approaching that limit.

But gosh its' fun though.

Had another thought. What if the loop on the bury around the ridgeline had a nacrabiner type slip-loop on it. You could tie a lanyard knot (stopper knot) into a piece of shock cord on a bight and lark's head that onto your tarp, then the lanyard knot ball could fit through the slip-loop to attach your tarp to the ridgeline. Kind of like a cut-apart nacrabiner, the loop end attached to your ridgeline via a bury, and the stopper knot permanently attached to your tarp.

Does that make sense? I think I am gonna try it.

I think I agree.

This is getting way too complex, but it is an interesting exercise which may bear fruit elsewhere .

I'll look forward to some pics.

But as TF said, this may produce something that can be used elsewhere.

I think I see the point. You could tie a diamond knot out of one piece of line through the D-ring or eliminate the ring and go through the webbing on the tarp. Then make a length of line threaded over the ridge line that will bind down with either a fixed loop to tie a larks head around the diamond knot or a slip loop to come around the diamond knot. To me the advantage is that there is no way for this system to "fall off." You couldn't lose this set-up unless you tried. Great idea for a kid set-up or scout troop. Us older people are always so observant we would notice if we lost things
