    "Standard" length ridge lines

    I was thinking about this , and yes it hurt. If the optimum sag is 30°, then for a fixed length of hammock, shouldn't there be a fixed length of ridgeline to accomplish that sag?

    Yes, yes, that does depend on exactly where you attach the ridgeline, and others may prefer more or less, but assuming you are attached exactly at the end of the hammock, there should be a very small range to accomplish this sag. No?

    I am poor at my arc length and tangent math. Are there any math wizzes out there who can assist?

    i believe the preferred length equals 83% of the length of the fabric of your hammock. the 83% length should be the distance from either end of the hammock while hanging, if that makes sense
    ...in it for pics.

    The loose rule most go by is about 83% of the length of the hammock body. Like you said though each person is different and some like a little more or less sag from there, but it is a starting point.

    For a typical 10 foot (120 inch) hammock, a 100 inch ridgeline is considered standard. Small adjustments from there will enable you to fine tune to your liking.

    With an Adjustable Structural Ridgeline (or Adjustable SRL) you can adjust to almost any length you want until you hit the sweet spot for you...or you get tired of tweaking and simply fall asleep.

    WhoOpieslings .com sells adjustable SRL's I believe, they are cheap because you don't have to buy any more line than needed, they are ready to use, and I believe they are made from 2.2mm Dyneema or something like that.

    Maybe, SmokeBait would like to chime in and tell us the exact details.

    Happy trails,

    You are right on Barefoot Child. We use 2.2mm Lash-It or Zing-It made from Dyneema fiber. The finished product yields an adjustable length from 81-116 inches. We are we going to build that "special" one for you?

    I think I see part of your confusion. I have never seen the 30 deg referenced for sag. The 30 deg is in reference to the angle of your suspension line to the tree. Sag is completely subjective. I have yet to try a ridge line on my gathered end. When I do I will start with the recommended 83 percent and adjust from there.

    The opinions expressed by this user are not those of a competent individual. If they were that would mean I know what I am talking about.

    Otter,
    Thanks. Actually right after I posted and was giving it some more thought, I realized that the 30° was referring to the suspension, not to sag. I was hoping someone would bring it up here. Thanks. With the 83% rule, I think I can figure it out. And I do like the idea of an adjustible SRL. I will need to look into this further.

    Any other suggestions regarding adjustible SRLs?

    I use adjustable structural ridgelines (ASR) on my loaner hammocks. For the exact reason mentioned. Everyone is different in their likes and dislikes. So the ASR allows them to dial in the amount of sag that is comfortable for them.

    Opening up the thread again, but taking the discussion in a new direction. I am making a whoopie SRL for the SBPro. 83% is 104". Help me calculate the length of the whoopie, if I want good range from, say 96" to 112". I am using a locked brummel on teh fixed end with a 6" circumference loop.....
