Yeah,

It is the same fundamental geometry equation I use to to set the sag
of my hammocks without a ridge line. You can attach a ridge line
away from the hammock body along the hammock support ropes. The
equation I use to approximate the horizontal distance between two
points on a hammock (this would be your ridge line length) with a
particular sag angle is:

Horizontal Distance = Hammock Length X cosine(sag angle).

For a 30 degree sag angle, the cosine(30 degrees) is 0.87, so if you
wanted a 30 degree sag angle you should measure a horizontal distance
of 8.7 feet for points on the hammock support ropes that are 10 feet
apart, measured along the curve of the hammock.

I personally find that I don't want the ridge line and don't need it
to set the sag of my hammock. A ridge line gets in my way and I only
use a stretchy nylon ridge line that doesn't set the sag on the
occassions when I need my bugnet. There are several things you must
do to properly set up a hammock and setting the sag angle is just one
of them. You still need to center the hammock, set it at the right
height and either level it or slightly raise the footend depending on
your preference. Once you master those things setting the sag angle
isn't a big deal, it is just part of setting up the hammock and you
do it without really noticing it because centering the hammock,
getting the right height, leveling and getting the right sag are all
interdependent. But if you want a ridge line, have at it and good
luck with it... remember that a load bearing ridge line puts more
load on the hammock support ropes so you probably want them to be
stronger.
