    Constriction for tarp ridge line adjustments

    I have arrived late for the Whoopie Sling party, so I am learning... I got some tech line from Scott at DIYSupply yesterday. (Great vendor!) I made myself an adjustable structural ridge line that I hope to try out over the weekend. I was looking at videos showing tarp ridge lines and was wondering if anyone has tried threading a few inches of whatever brand of hollow core line you use for a tarp suspension onto your ridge line with a loop (locked Brummel?) hanging off the end toward the tree for attachment instead of a Prusik knot? Has anyone tried it? Seems like it would work for centering the tarp as well. I'm sure someone has at least tried this, and it may be common. I am just having a hard time seeing illustrations with that option. Thanks.

    not really sure what you are saying, but here is the problem with whoopie type suspension for a tarp. you would need "tree huggers" and you couldnt run a continuous ridgeline.

    I was afraid I wasn't clear enough. I just saw a video on youtube by 1377stick where he was using a continuous tarp ridgeline made by Whoopieslings .com. The line was wrapped around the tree and attached with a Knot Bone on one end, and the adjustable end came around the tree and attached to a Prusik knot by a Figure 9. I was just wondering if you couldn't replace that Prusik with a piece of cord threaded on the line forming a constrictor type knot. A sleeve with a loop hanging off for attachment by the same Figure 9 if you will. Make sense?

    Have not seen the particular video but I think I'm understanding what you want to do.

    I have thought about doing something similar with a "UCR" rather than a whoopie. The UCRs do not require as much line but don't constrict as well. For a tarp line that is not supporting your body weight the lack of constriction might not make a difference.

    Prusiks are just so much quicker and can be added/removed easily. I've never bothered with anything more fancy.

    It sounds as if you're talking about adding a UCR to a ridgeline. It is certainly possible, my only concern is that tree spacing differs from one set to other, and you would need some seriously long UCRs to make such a thing work, or you may not have enough room for them to adjust properly. Prussics solve this problem because you can slide a prussic knot along the entire length of the ridgeline.

    I am not really talking about using Whoopie slings specifically for this. It is a continuous ridgeline, your ridgeline gets buried in a section of cord that can remain permanently. I have attached a really badly drawn illustration in hopes it explains my idea.

    And it is upside down. Great.

    All I am saying is replace the Prussics with this idea. Leave the knot bone, figure 9 or whatever to make the gross adjustments, then use this constrictor idea in place of just that Prussic. It stays in the middle closer to the tarp itself. I hope the illustration helps. Thanks for looking ya'll.

    I think he's talking about simply replacing the prusik with a constrictor. There isn't any reason why that wouldn't work. A constrictor might slip a little more easily than a prusik, but there are ways around that. I use UCRs rather than Whoopies for my hammock suspension. Constrictors would take up a little more length on the line than a prusik, so it might increase your minimum hang distance slightly.

    You are burying a piece of Zing-It inside the ridgeline for adjustability, correct? If so, you will find that you have the same problem that people have when they try to use whoopie slings to tension/attach their tarp to trees. I tried using whoopies but it didn't work out. And what you are suggesting is essentially a whoopie without an adjustable loop.

    The problem you'll encounter is that you need two hands to adjust the whoopie (or your method of bury), but you need a third hand to release tension on the bury so it can be adjusted (by pulling the ridgeline towards the tree). You can try holding the ridgeline with your teeth, but I doubt your dentist would approve.

    The prusik (or a prusik with a Figure 9 or Dutch Tarp Flyz) does not require three hands and will work much better. Go ahead and try your method (I tried whoopies even though every post I read said it wouldn't work very well). Sometimes you have to do it yourself to understand why it won't work.
