hey dave... i've been wondering about an idea that someone else brought up a while back.
what if you had a length of webbing that went from tree to tree.
at two points that were the right distance apart, there would be attachment loops sewn onto the webbing were the hammock would be attached.
but as i type this description, for the first time, it has occurred to me what would happen.
unless the long ridge line webbing was extremely strong & tightly stretched, it would sag in the middle (between the hammock attachment points) when the hammock was weighted.
...so never mind:~}

I uploaded a spreadsheet to the Files section (
idgeline.xls ) where I try to show what my concerns are with some hard
numbers. Obviously I had to make a few guesses and approximations,
but I believe the general jest is correct and is something to be
concerned with. For instance, I don't think you want to just tie a
hammock with a structural ridgeline off at some height and then
tighten the suspension lines until it hangs at the height you want
without taking into consideration the distance between supports. The
sloppier one is with selecting that height, the higher their
likelihood of ending up with some very high forces.
Forgetting about the trees, what's scary to me is that these force
numbers are not particularly bounded but the strength of the
components do have bounds. In the final analysis, I would want to set
up a hammock with a structural ridgeline like it didn't have a
structural ridgeline unless I couldn't tie it off that high.
don`t leave the CREATOR out of the creation!!!
