The Sheepshank
The most famous and useful of
rope "shorteners," this also is a
"strengthener". as it supplies triple
strands at any portion of a single
rope.
Take a bighlnear the cenrer of a
rope and take another bight in the
FORMA opposite direction, one running
DOUBLE upward, the other downward (fig. 1).
BIGHT
For simplicity, assume that the
upward bight is at the left, the stand·
ing part of the rope at the right.
Twist the standing part to form an
underhand loop and slip it over the
fig. 1 upward bight. pulling the loop tight
so that it is practically locked in place
(fig. 2).
--, Now do the same with the downw.
~ LOOP
, OVER nrd bight, but in reverse fashion. To
\ simplify this, turn the rope upside
down so that you will be performing
exactly the same operation as before.
The result is simplicity itself - two
oPlX>Site bights in the cenrer of the
'\ rope, each gripped by a Half Hitch
'12 (fig. 3). The harder you pull on the
HITCH
rope ends, the firmer it becomes. If
there is any danger of a slip, insert
two toggles or bars through the loops
that project from the circling Half
Hitches.
