Continuous ridgeline for hammock (not for tarp)

[Daibhead]

Hey everyone, I’m looking for some input on a couple ideas I had.

First, why doesn’t anyone create a continuous ridgeline of amsteel suspended between two trees, and then hang their hammock from prussics on that ridgeline? I’ve seen it done with rock climbing rope because that’s what was on hand. Seemed to make sense, and it could potentially use less amsteel than a whoopie at either end.

My second idea is similar to the first. If you’re going to use two amsteel whoopie slings and a zing-it structural ridgeline anyway, why not create a zing-it dogbone ridgeline, then make your adjustable loops of the whoopie slings thread trough the bights on the dogbone? It would permanently connect the three, effectively creating a bi-material, adjustable, continuous ridgeline. Then you can use toggles or carabiners to connect your hammock to the dogbone.

Has anyone tried either of these methods, or have any good reasons not to bother trying them?

Thanks!

Btw first time posting!

Not sure about amsteel, but have heard of this being done from a slackline.

I have toyed with trying it when I next want to hand somewhere with trees too far apart for my normal suspension.

I mean, I guess it would work. However, the CR between the trees is probably at 0 degrees on both...so you still got that crazy load on the trees when you get in the hammock. Running it thru the hang calculator, (had to use 1 degree) the shear force is 5,729 lb for a 20 ft distance and a 200 lb person. Pretty sure the shear force on a big pile of mountain would be insignificant compared to the tree. At that point, you're only worried about equipment failure. I've seen those folks that are high lining between mountains: https://nypost.com/2014/09/19/highli...-italian-alps/

You could probably rig up the CR to droop at the 30 degree angle however I dunno how high up the tree you'd have to go or how long the CR would need to be. I guess the math would be the same for suspension bridges.

I dunno, I been drinking since after lunch.

I'm pretty sure Meyers did something like that. I'd have to search up the vid to see if I'm remembering correctly and share it. My bad, I must have seen it somewhere else. But this sounds like what you're talking about, from '08,

Single Line Suspension (SLS)

Rather than using prusiks on hammock ends to a continuous hammock ridgeline-suspension, use a marlin spike hitch and strong toggle on each end attachments. A continuous loop could be larksheaded to hammock and larksheaded to amsteel continuous ridgeline—just to outside of marlin spike hitch.

Or you can tie alpine butterfly loops in suspension and clip your hammock continuous loops to butterfly loops with hammock rated carabiners.

Hammock rated carabiners rated around 2000 pounds
And if hanging real high off a slackline, use climbing rated carabiners maybe rated 5000 pounds—I don’t know—I’m skeeeerd of heights!

This way there will be no slip of amsteel on amsteel which would burn your amsteel if prusik slides. And it will slide.

Don’t ask me how I know. Short story—my prusik suspension slid one night and turned amsteel black—severely weakening suspension!

Possibly you can get away with using prusiks using two different diameters of climbing rope.
The skinny rope forms prusik and the fat rope is your hammock suspension

Good luck

As long as you suspension holds your carcass high and dry off the ground—it’s a winner!

My thought has been to have the hammock CLs attached to a couple UCRs on the main line. Then it's position could be adjusted as well as the hang.
Setting the 30° from the trees to the hammock shouldn't be any harder.

hmm, okay, that could be a step towards fixing the prusik problem (although the angle between ridgeline and hammock cl's seems a bit problematic for a UCR burry). and the possibility to move the hammock at will once setup looks tempting (so maybe a reason to consider such setup), but there's a problem: if you move the hammock close to one tree and farther from the other, without moving the suspension high on the far tree and low on the close one, then you'll end up with uneven rigging angles (namely, very low angle on the far tree, so overloaded suspension), not to mention tilted hammock ridge.

if i would try, i would keep an adjustable ridgeline (like a ucr), separate from the whole "continuous suspension", to serve as a "sag yardstick", so that when i move the hammock i don't have to find the previous sag again, as it will be set when the "yardstick ridgeline" is taut, this would make experimenting with moving the hammock much faster

I think if the hammock to UCR shuttle was a soft shackle (or such) and included main line it would avoid the bad angle on the burry.

The "yardstick", I'm w/ you on that. I was already thinking about the other purposes it would have to serve if I was going to carry it around. It would probably just be a couple/few dogbones that I'd carry anyway linked together.

I have been dealing w/ exactly that w/ my current setup.
I'm running short tree huggers to a dogbone and directly to my CL.
The other end of the hammock goes from the CL to a UCR and then the hugger.
The dogbone end is closest to the tree and usually my foot end, which is about a chakra higher than my head end.
The hugger at the head end gets placed based on how far of a span I have to bridge. I get as close to 30° as I can but trees can be scarce around here.
I think this be came my "standard" from doing so many one tree hangs. Where we are it just bumps the hang options into the "acceptable amount" range.
The above description is when we do have two trees that will work. When I have only one tree my head end is the pole and my feet go to the tree. "Usually" the tree will be taller than the pole I use (6') and my foot end can be higher.

“CL” = “continuous loop,” yeah? Sorry, what is “UCR”?

Also that SLS you shared is not quite what I had in mind but looks very interesting! I’ll have to play with that setup a bit.
