I've seen videos when the structural ridgeline (HH or WBBB) is grabbed flat and then the hand is turned 90 degrees or so. The "word" is, shouldn't be tight like a guitar string, shouldn't be weak like (can't think of anything without being politically incorrect).
But is that with the hammock empty or while you are in it. Because I had a WBBB with the near 30 degree suspension ideal and a friend in it and I couldn't begin to torque that ridge line. Same when I was in my HH Survivor.
So I think I'm missing something about that "how tight is tight" test?
If the trees are far apart - like 17 ft or so, dropping the angle only seems to lower the hammock to the ground. it doesn't bring the ends in any closer, which would be what's needed to put slack in the ridge line.
it just seems like if I put 200 lbs. of body in a hammock, that 200 lbs is "loading" the hammock and putting tension on the ridge line. Torquing the ridge line means bringing the ends closer together and there is 200 lbs of body in the hammock keeping those ends apart. It seems like bending the ridge line would lift the hammock a bit, just like tightening the suspension. So the amount of effort to torque the line is influenced greatly by the load in the hammock - or is that just a load of something else?
How critical is it?
