The guys who make the Four Knots uphaul also make a waist-harness with
a metal clip on the end named a Puppy Pull. It is for a hands-free
leesh for your dog, but the thought was that you could attach it to
some line that is in turn attached to a second mast base behind the
primary mast base.

Advantages to this design are:

1) You have an emergency release at your fingertips, so if you are
trapped under the sail you can release yourself.

2) You can release yourself easily if the line wraps around the rig.

3) The Puppy Pull has some elastic qualities, so it can absorb some of
the force of the rig reaching the end of its line and pulling.
