Structural Ridgeline – whoopie sling style, with two 1.75mm Lash-It soft shackles.
Material – 1.75mm 500lb test strength Lash-It by Sampson.  This is the same material as used to make Amsteel Blue by Samson.
Color – Yellow.  (Also available in Silver*, or Red)
Adjustable – 76 inch minimum, 135 inch maximum.
Fixed loop end – 2.5 inch loop, 10 inch bury.
Three Problems with Whoopie Sling style Ridgelines:
1.  7/64 Amsteel Blue is unnecessarily heavy. It is commonly used
because it is easy to splice.  This size is ideal for Whoopie Slings to
attach to the hammock and to tree straps.
2.  The tag end of
the Whoopie Sling tends to hang in your face or dangles on your feet,
so most try to solve the issue by attaching the tag end to a prussic
knot, tie the end of the tag end to the ridgeline, or construct the
Ridgeline so that the hanging end hangs out of the hammock, hopefully.
3.  A bead is used to keep the whoopie end from being pulled in on
itself, which is fine for 7/64 Amsteel Blue, but not the most eloquent
solution for use with 1.75mm Lash-It.
How these three problems were solved:
1.  1.75mm Lash-It
has a strength of 500lbs which is more than required for a structural
ridgeline. Hammock campers who use fixed ridgelines have long preferred
and used material and the only reason sellers don’t use it is that it’s
tedious to splice.  The end product is worth the time and effort
required to use the correct material.
2.  The solution to
the hanging tag end problem is best illustrated in the second photograph
showing the entire structural ridgeline loosely coiled and in the
outdoor photographs.  The use of a small fixed loop which is made with a
locking brummel splice and a bury, the same procedure used to make
fixed loops on whoopie slings, so the loop is fixed and will not open or
close, rides on the ridgeline so there is no hanging tag end.  The
second part of the solution for this issue is addressed is that the tag
end does not vary in length, as the whoopie loop is adjusted, the short
tag remains a constant short length.
3.  To address the
problem caused by inadvertently pulling the whoopie end of the ridgeline
in on itself I came up with a very simple solution.  Instead of the
traditional bead, I place a small “stint” placed in the beginning of the
formation of the whoopie loop which makes the Lash-It too large to pass
back into itself.  The “lump” the stint forms can be seen in
photographs nine and ten which were taken on a cutting mat with one inch
squares for a since of scale.  Photograph nine shows the whoopie end
almost as closed as it can get, and photograph ten shows the “stint
lump” on lower leg of the whoopie loop.

Minimum closure of whoopie loop end.  This photo shows the whoopie loop
end of the ridgeline closed as much as possible due to the stint that
insures that the loop cannot be pulled in on itself, again on the
cutting mat with 1 inch squares for reference.

*Please
note that red, and yellow are made with Zing-It rather than Lash-It.   Lash-It and
Zing-It are the same material in every way, made by the same company
with color being the only difference.  Silver is called Lash-It.  Red, and Yellow are called Zing-It.
