Try tying (Elastic) cords to the lines on the Bayer. I did it once & that pretty much stopped the swaying (I put em on to widen the hammock) It stopped it so much I took em off immediately.
I used 1/4 (may have been 3/8") inch bungee cords, on on each corner tied to TWO of the suspension cords, then to wire stakes in the ground. I pulled them just snug, so the hammock would move as I got in it, but "zero" & hold the hammock apart. It really didn't give me the extra room I was trying for, but did stop all motion.
This was a ONE time test 5 years ago, so you may have to play with it a bit.
When you have a backpack on, no matter where you are, you’re home.
