Allen/shroud covers
Helen Horn2010-11-15 23:52 UTC
Yes, ours are easy to spin, the shrouds were shredding the sheets, the knots
need improvement, an eye splice could be a really good move to make it slippery,
but then the sheets can't be interchanged as easily. We have lots of tuneup to
do before our 36 hits the race course. Helen

Thus my question about the soft shackle. The idea being to have eye splices
in the sheets but not permanently attached to the sail.
In case someone hasn't seen them:

Pardon the really dumb question but if the knot is larger then the opening
which it has to be for the eye spice not to slip, how do you get the loop
over the knot? Typically like my dog collar made of elongated metal links to
prevent chaffing, you slip the chain back inside itself to create the loop.
However, this method would not work on the foresale as you need to pass the
it through the grommet opening.

The eye opens up easily as there is several inches where the Amsteel splice
can slide.

And here is how to make them. There are easier ways to make them but I like
the looks of this knot as it is big so the shackle should be more secure.

I am going to make my first two tonight.

OK I get it, variable loop size that holds together similar to chinese
finger grip. OK Im sold. These should be easy to make and multifunctional.
What kind of loads or is there a sizing/load chart somewhere?

The one they have in the how-to video is their largest and it is made from
3/16 Amsteel and they rate it at 5000 pounds. YMMV. I just finished making
one and have it in my hand. I had a little trouble following the knot in
the video but it is a Diamond Knot and used Wikipedia as backup. The
Amsteel is rated at 5400 pounds and as it is doubled up in the shackle I
guess it is 5400 * 2 less the loss from the knot so 5000 sounds reasonable.
Just ran some numbers here to see what strength I need. My 7/16 line is
rated at 5800 pounds and a bowline is rated at 63% (thanks Google) so I have
3650 pounds. With the eye splice I have maybe 5000 pounds left and that is
a perfect match for the soft shackle made with 3/16 Amsteel. It should be
about 40% stronger than using a bowline. I had a line shatter once a long
time ago. It is a memorable experience. I replaced all my lines after
that.
