That was a vertical lift and I put the fixed end around the hoist hook and the adjustable end around and eye bolt holding an 830 pound injection mold.
Is 830 good? Well it aint great. But great is only 170 pounds away. Yer are dynamic forces that are applied when in the hammock. You bounce and what not, plus the angle has a lot to do with it. One time I set up a hammock with a pulley and a large weight on a scale. I bounced pretty good on it and I could not get more than 225 pound of force on one side. I weigh 200 pounds. You have to use your own disgression since it is literally your butt. I'm not sure I want it on my hammock that I use often, but I might put it on my cuben since i am already real gentle with it and the whole point is to be low weight. I will also use it for tarp suspension and ridgline. It might be good for tie outs, but I really like speer no tangle for that. I alsl might run one line completely through another and use a marlin spike hitch.
