I have been using a MacCat Deluxe for a year now and using a pair of long zing-it lines for a suspension. I wrap the zing-it around a tree using a stick for a toggle and then out to the tarp where I have a Nite Ize Figure 9 to tie it off. It works OK but the zing-it has a tendency to slip in the figure 9 and there is a lot of zing-it hanging around when I am done.
I have spent the past few hours exploring options and believe I have something that will work better, with the added bonus of requiring nothing other than zing-it and a couple of sticks.
I started off with a 40' length of zing-it for a ridge line, and 2 2' lengths of zing-it for tarp tie-offs. I marked the smaller lengths at 1" from one end and 6" from the other end. The two tie-offs were then spliced over the ridge line, one on each end. The longer ridge line burrows into the tie-offs at the 1" mark and comes out at the 6" mark, with the 2 6" sections toward the middle. I put a small loop at each end of the ridge line and tied the tarp to the tie-outs using a bowline.
To setup run the ridge line around one tree and fasten it back to itself using the end loop and a stick. Repeat at the other end. The ridge line will be lose and sloppy, but you can easily adjust the position of the tie-outs to put the tarp where you want it and tighten it up fairly well. There is a loop of unused ridge line under the tarp but that can be coiled up out of the way easily enough.
I am interested in any comments or suggestions. I have not had it out for a night yet, so something may yet go wrong, but it looks workable so far.
