Agree with Gunner76. Also use http://theultimatehang.com/hammock-hang-calculator/
to check and verify your settings. You can scroll down on that page or get the App.
As a newbie - I made a cheat sheet for each hammock and my preferences.
Some of the inputs do not change (given the same hammock):
- Ridgeline Length: I believe the WBBB ridgeline is fixed at about 100"
- Preferred Sit Height: use what you will, i use 18"
- Weight in Hammock: Your weight ###, plus a few for quilts, gear, etc.
- Hang Angle: 30* (for the Blackbird)
So, given the same hammock, only the Distance Between Trees will change
I write down the resulting Hang Point (Tree Strap Height) for different Distance Between Trees possibilities (11',12',14',16',etc.). Yup, I carry a cheat sheet.
Then record the suggested Suspension Length for each Distance Between Trees onto the cheat sheet
In the Piney Woods:
I've been known to carry a lightweight tape measure if not hiking long distances...cause estimating - umm not so easy for me. (<--<<< Noob!)
Once two suitable trees have been selected - and the Distance Between Trees is accurately determined:
- refer to the written correct Hang Point measurement (strap height) and hang both straps.
- next, before hanging the hammock, I set the suggested Suspension Length (distance between the tree and the hammock (less any loops on the hammock itself).
- Now, attach the hammock and the Hang Angle should be pretty close to 30*
Finally, I'll tighten the footend strap or whoopie to raise the footend a few inches for the WBBB (over 1' for the XLC).
From here fiddle with things until you have a comfortable lay. Hope that helps!
