We can't have it both ways with UQ's on rails. We can't have the fore-aft adjustability of the UQ and have the ends or sides of the top of the UQ pulled up taut against the bottom of the hammock unless the UQ has some intrinsic longitudinal stiffness or resistance to sag and folding. Shorter, more stuffed, and synthetic sheet-filled UQ's may all have that resistance to sag or folding. Think WB Yeti.
If we want to keep rails, and taut, then either we
- pull up with another loop from one side to another, as Shug does,
- pull up with interim short elastic cords attached around the middle of the hammock sides, OR
- we need another pair of elastic cords pulling the UQ itself outward -- and by weak translation of forces -- upward.
Yes, you can make the elastic in the rails very tight, so tight as often recommended here that the hmmk is lifted up. My experience with that approach is that it squeezes the hammock narrow, as it must--the statics are easy to calculate, and it makes the hmmk painful to try to sit on.
Everyone, thanks for all your tips and advice. I think I will get me couple of those thermometers. As for the CBS, I am hopeful that it's just a matter of closing the gaps of my UQ. After all, as I said, I was totally warm everywhere except the low hanging bits of me. Shug's lifter was what I was thinking about. The Zeppelin has loops already, I am going to try some shock cord and some mini biners I already have and try hooking the up to my ridge line.
