Zeppelin Bend
A zeppelin bend (Figure 14) can be used to attach two
lines, and it is a good choice when the lines will be heavily loaded. It
is a symmetrical knot that is easy to untie.
To tie: Form a loop in the
end of each line, one clockwise and the other counterclockwise, with the
ends behind the standing parts. Flip over one of the loops such that the
end is in front of the standing part. Place this turn on top of the
other with the working ends pointing in opposite directions. Pass the
working end from the top down then up inside the two turns. The end from
the bottom comes up and down through the turns.
Girth Hitch
The girth
hitch (Figure 15) is used for attaching loop slings or eye-spliced
slings or ropes to an object. It also can be used as a midline knot to
attach tools to send to the climber.
To tie: The girth hitch is made by
simply taking a wrap around an object with a loop and passing one end of
the loop through the other.
Cow Hitch
The cow hitch (Figure 16) often is
used for securing hardware to a tree. It is a variation on the girth
hitch but is formed with a line instead of a loop.
To tie: The cow hitch
can be reeved by passing the working end around the tree to form a turn,
under the standing part, and back around the tree, with the working end
exiting in the same direction as the standing part. It resembles a
Prusik hitch with fewer turns. When both ends of the cow hitch are
loaded, it is called a girth hitch. The cow hitch can roll, so the
working end should be half-hitched to the standing part. The direction
of this half hitch should be against the bight so that the working end
exits back along the direction it entered. The end should be tucked
under the turns around the stem to eliminate the potential for the tail
to be pulled into running rigging.
