# Thread: 25 to 30 degree hang angle...

1. Been fiddling around with angles myself -

From the diagrams I'll assume the 30 deg with zero load.

The ridge line is then set with the full weight of the occupant (otherwise it would sag quit a bit) then left at that length as a guide for future hangs... more or less.

Am I Captain Obvious here, or did I miss anything?

edit:

One angle I haven't come across in the angle where the suspension line and ridge line meet ... on the top side. Somewhere around 150 degrees ... ish?

You got it exactly right.

And the ridgeline/suspension angle will be 180 - suspension angle...so 180-30=150*.

The angle were the ridgeline meets the suspension line is 30 degrees on the bottom side so it would be 150 degrees if you extended an imaginary line through to the top side. I did some quick trig calculations (an online calculatorfor sines and cosines and stuff) and figured the exact length of a structural ridge line to create a 30 degree angle with my hammock. All I do is string the ridge line up between to trees, be it 50ft apart or 15ft, as long as I hook my hammock up to the predetermined spots on the ridge line it will always sag the same.

4. I may give my mason's line level a try at this since 180* for the ridge line is apparently the goal. Then add a little angle up at the feet since I've found that to be comfy. Line level is small and weighs little to nothing.
