The problem with using any "constrictor type" implement, be it UCR or whoopie sling, in a scenario where you need tension is they do not tension well (or untension well) when strung tight.
You would not be able to get your ridgeline tight enough and if you were able to, you would be unable to untension it.
I didn't know that the constriction type systems don't play well together if the line is always tight. I know with whoopie suspensions they are slack until you get into the hammock, but what I am talking about would be under constant tension. Thanks for the education everyone!
I knew in the back of my mind there had to be a catch because it seemed so obvious to me. I have been using Prussics and 550 cord to hold my good old Wal Mart tarp up. Guess I'll stick to that system with the better line. Now I have to buy more cordage from Scott at DIY!
I think Dyneema is like kudzu. It keeps growing in my kit! I am going to see if the soft shackle I made will dump me on my blessed assurance before I make another one to replace my monster 'biners!
Your tarp rides on the ucr's and moves easlily. Once you pull the guylines out, it is tricky to do any adjusting. But that can be said for prussiks or any other type of connection/ridgeline option. You normally gotta slacken up the guylines for rl adjustments.
Center the tarp (like any other rl set-up), then stake it out and your idea works fine.
I'll see what I can do about some pics...
I apologize. Using the UCR as a connection point for the tarp to the RL to position the tarp would work fine.
I thought we were referring to using the UCR or whoopie sling as the device to tension the RL. That's when you'd run into issues.
I was actually thinking they could work in both cases. I didn't know about the problems using the idea under constant tension.
