Ever since I began hammock hanging, I've had trouble with with my tarp slipping on the ridgeline overnight, especially if its windy. Prussicks and Klemheist hitches both slip, even with extra wraps, on 1.75mm Lash-It. So I decided to try something different. After backyard trials this weekend, in rain and a little wind, I'm pleased with the results -- no slippage at all after 3 days.
So what I did is this -- I made a constrictor with a locked brummel in 1.75mm Lash-It. Burned the end to make a little button that wouldn't fray, and to eliminate a pigtail (as I had in an initial design. The pigtail kept getting bumped and releasing tension on the constrictor.) I placed a small nail in the end of the Lash-It before I held it over a flame. This kept the line open on the end. The loop attaches directly to the tarp d-ring, eliminating a biner. The ridgeline runs thru the constrictor and exits just shy of the bury of the eye splice.
I made them longer than is necessary so if it does get bumped there is still plenty of bury to hold the tension on the tarp. I'm really pleased with these, but I'm not sure what to call them. Any ideas?
