I'm not sure how you are using it. 1100 lbs wouldn't worry me too much
for your weight if you are using a hammock without a structural
ridgeline and are setting the hammock sag around 30 degrees. In that
case the static load on each suspension line is pretty close to your
body weight. However, if you are using the 'initially pull everything
taut' technique that some folks are using, particularly hammocks with a
structural ridgeline like Hennessy uses, then I would be a little
worried because you might be putting several times your body weight on
each suspension line.
Again, I'm not sure how you are using it but the bowline with a quick
release is very easy to tie/untie and holds very well with slippery
rope. With not so slippery rope, it is not that easy to pull the quick
release free-- I had trouble getting my Hennessy to slip from the quick
release a time or two. I had the nylon webbing on a twin-layer hammock
actually melt from the tension/stretching at the knot and had to
literally cut it off of the tree. It is important to not use the wrong
knot for the type hammock suspension line you use... not only does it
have to hold under pretty high loading, you also want it to
untie/release in the morning! That bowline with a quick release is
what I have been using for my rather slippery poly rope and it is what
the Clark Hammocks use for there poly rope. I suspect that it is
easier to use than many of the 'easy' attachment schemes that I have
seen for hammock suspension lines. If you are not familar with bowline
with a quick release, there is an excellent illustration on Clark's web
site in his online manual.
