rain, with & without wind) using Jerry's wrist rocket tubing scheme
for the fly and haven't had the problems you noted and I've got an
HH Ultralight Asym which does not have an overly large fly.
I still use the same cord attachments for the fly to ridgeline that
shipped with the tarp. It's *critical* that the fly be centered over
the hammock. Even with snakeskins it can shift around between uses
so I check it every time.
The rubber tubing from a wrist rocket slingshot is attached to each
of the fly tie-out rings. Attached to this is the standard Hennessy
black cord (non-stretch). If rain is expected I tie out the fly to
the same stakes I use for the hammock sides except that I stretch
the rubber tubing about half its limit. That way as the fly moves in
the wind/rain there's enough give to move a bit (but not nearly like
your overhead see the sky experience). If the fabric "shrinks" it
simply pulls on the rubber tubing maintaining tension. If
it "stretches" the tubing still can pull it tight.
If rain isn't forecast, I do the same thing on one side and on the
other I fling the fly over the top of the ridgeline so it's on the
side that's tied-out. Then I run its cord over the ridge to a loop
of cord I have attached to the stake and up into the hammock where I
tuck it into my shoes (I hang them from the ridgline when I sleep).
If it starts to rain, I sit up, grab the cord, pull it tight--which
pulls the free side of the fly up over the ridge and then tightens
it up, tie it off to the ridgeline, lay back down and go back to
sleep. (I picked this up from either Shane or Sgt. Rock and they
have my everlasting gratitude.)
(I'll give up my HH when they pry it out of my cold dead fingers
If you go to WallyMart they have a set of replacement tubes & pouch
for about $4. The pouch is a little leather oblong that has a hole
in either end which the tubing is attached to using what looks like
a larkshead knot.
What I did was cut the leather so I could pull the tubing off. That
leaves a tube with a loop in the end. If you're using a grommet or
plastic ring like the Hennessey uses on the fly then you need to get
the ring inside the tubing loop.
The secret is that the tubing is simply a tube. On one end they poke
a hole in one wall of the tube. Then they lay the pouch on the tube,
reach through the hole, grab the end of the tube and pull it through
the hole so it ends up turning inside itself.
It's much less difficult to do than it is to picture from this
description though. First you'll want to soap it up to make the
rubber slippery. Then you can grab the loop with a pair of needle-
nose pliers and pull it back out of itself. Then you can reverse the
process by using the needle-nose pliers again to reach through the
hole and grab the end to catch the ring or grommet. The first time
you do it you'll puzzle over it. The 2nd time you'll just do it.
In fact, I don't bother pulling the tubing out when I do it. I just
cut it off just below where it connects to the leather pouch. Then I
poke a hole using a shish-kebab skewer about 3/4" from the end. I
push the nose of the pliers through the open end of the tube & out
the hole I just made. Then I pull the other end of the tube through
the ring and then place that end in the jaws of the pliers. Then I
pull it through and when I'm done I've got that nice neat connection
around the ring.
On the free end of the tube that attaches to the tie-out cord I use
a small (1/4" dia) nylon spacer (Home Depot, 50 cents, you'll find
them in the drawers of miscellaneous hardware) I thread the end of
the cord through the spacer (it's a hollow nylon tube) and tie a few
overhand knots to make it large enough not to slip through the hole
in the spacer. I put some Crazy Glue on the knot to make sure it
doesn't unravel. Then I soap up the nylon spacer and shove it into
the end of the rubber tubing. You'll need to fiddle with it a bit to
get the thing in as it's a tight fit and you'll want to make sure
the end of the tubing comes down over the end of the spacer but once
it's on it's not coming off again unless you roll the tubing off of
As they say, this thing is "bulletproof". I've not had any issues
with the connections of the tubing. When I hang my hammock I tie it
to a stake or tree with the tubing stretched. Then as the fly
loosens up the tubing takes up the slack. I don't think using an
elastic cord like the Hennessey's hammock tie-outs use would work
long term as they tend to loose their stretch over time when
regularly tied out in a stretched mode. The rubber tubing is a
surgical grade rubber that doesn't have a problem being tied out
stretched and then returning to it's unstretched size.
I don't think this whole thing weighs more than a couple of ounces.
