I've been hammock camping for years. (well over 12 years)
I saw people talking about whoopie slings for years, but never looked into what they were.
I'm ashamed to say it was just last year when I finally looked into what whoopie slings where exactly. I immediately switched out my suspension to use them. Wish I would have done that years ago. LOL
Anyway I thought these would be great for adjusting tarps tie outs.
Found a few threads where people were asking if others had tried using them. Most of what I saw was people mentioned they would not adjust small enough, and when tightened would be difficult to loosen.
I thought to myself, I know how to make whoopie slings, what if I made some changes to see how they work myself.
I had some 2.2mm Zing It around, so I went to work making my whoopies for the tarp.
My finished project had an adjustment from 9" to 8' for my long side (porch mode) and 9" to 3' for the short side.
I've used them a few times now and have not run into any issues.
I had no problem adjusting, tightening or loosing, the whoopies. My locking length was 1".
