Sorry for the delay in posting my results. I have less than a week to wrap stuff at work before I head off to summer camp for a week (Camp Tesomas north of Rhinelander, WI).
My first night went without a hitch. We drove through the rain storms, and they were nasty storms at that, so I was able to set up dry. It did rain later that evening after we went to bed, but that didn't mater. The first problem I had was finding a place to hang. I had to keep it within the general campsite at the park to be near the troop. And most of the tree in and around the site were older, mature trees with larger trunks. I managed to find one with about a 6" diameter with one of the larger trees (maybe 20" diameter). So I threaded the support rope through the web loops and tied it off onto itself with a taught line hitch. The other end I was able to use the prescribed Hennessy lashing.
The evening started warm and muggy so I rigged a small O2 Cool Model 1041
fan with some cord on the ridge line. It cooled me off and lessened the effect of the humidity. It spun a little bit on the ridgeline so I had to play with the paracord to make a multipoint harness. For summer camp I知 going rig a leather strap about three inches wide with some snaps on it. The width should ride on the ridgeline and prevent spinning. It will hang by the battery compartment upside down. This will direct the flow right down the length of my body.
The next morning I awoke with my butt nearly on the ground. The knot and lashings held up so I assume it was the support lines stretching out with their first use. The resulting sag made my sleep a little uncomfortable. Nothing drastic but I was worried that I may not be made of the proper stock to be a hanger.
So I went about tightening the support ropes to raise the hammock. But it wasn稚 going up any noticeable difference. I could spend much time as we were preparing to head out for our hike up the bluffs.
Later at diner, I知 sitting at the picnic table trying to figure out what I知 doing wrong. Then it hits me! The tarp is attached to the support ropes and is taught. When I try to tighten the rope the Prussik knots transferred the energy to the tarp which was pulled as tight as it could get while the hammock slung beneath it lose. So all I had to do was loosen the tarp by sliding the Prussik knots towards the center, tighten the hammock to the desired tension, then retighten the tarp by sliding the Prussik knots back out towards the tree. A rookie mistake!
That night I slept beautifully! My feet were a little low so I slide down a bit to where my body was in line with the centerline instead of being turned. But it was not bad and next time I値l be sure to make my head a little lower.
I can also see another advantage of hanging your tarp separate from the hammock. I really like the compactness of rolling the tarp and the hammock in a single set of snakeskins and the quick set up and take down. But I think I値l start looking for a replacement tarp, like the OES MacCat Deluxe or similar tarp. I like the idea of 4-5 tie outs per side so you can close off the ends in foul or cold weather. More research!
Next week I値l be sleeping in it all week at camp. I知 going to set up a tent for my gear and for changing (it痴 a Boy Scout camp so I need to be discreet.) But I値l get lots of practice tweeking the hang and set up.
