Default Spectra, for luff pennants??

For many years I have used wire to make pennants to adjust the hoist on my
head sails. To raise the tack/foot off the deck or clear the lifelines. Or
on the head to raise the halyard swivel enough to prevent a "halyard wrap"
on the roller furling...

I recently installed Spectra for all of my lifelines and observed how easy
it is to do a splice, the ultra high strength and UV resistance.

I'm seriously considering making up Spectra pennants for all of my head
sails. Sure would be easier on the sail and sail bags when they are stowed,
not to mention weight and windage aloft. The working strength exceeds that
of my halyards.

I'm still wondering about some method to seize or hand stitch these sleeve
type eye splices. No mention of this as a problem in the single braid line.
I have not noticed any slippage in my lifelines (although there is some
noted shrinkage in length on hot days (only slight)).

I would be interested in opinions??

I'm not sure I understand your question entirely. Spectra is an ideal
replacement for wire rope for head sail pennants, although spectra is no
where's near as U/V or abrasion resistant as wire, it is much lighter and,
as you said, much easier to work with.

If you are eye splicing single braid Spectra by just tucking one core into
itself (Chinese finger trap style), then you are not splicing it properly
and your splices are at risk of failure. You -must- first do a "brummel"
splice, where the line entraps itself, then tuck the core. There are
instructions on how to do this on the New England Ropes website (and
probably other sites as well).

Once you've spliced in this manner, sure you can sew the splice, or as I've
done, use a "sailmakers whip". As you sew, be careful not to damage the
threads, sometimes a "dulled" needle works better for this.

Keep in mind, that when switching from wire to Spectra, you need to be very
careful to protect the pennant from chafe. Using a stainless steel thimble
(use a sailmakers thimble, -not- a wire thimble, no sharp edges) and perhaps
covering the thimble with leather will help.

Hope this helps,

Thanks for the "Heads-Up" on the splice. What you have pointed out, i.e.
"Brummel splice" instead of the "Chinese finger trap" is news to me. The
main reason I have concern since the finger trap method is what was
recommended by the salesperson that sold me the line.

I will try to find the referenced web site for details on the Brummel
splice method. Once I fully understand this method, I will redo my lifeline
eyesplices.

Chafe on the roller furled pennant should be a problem, but the hanked on
staysail maybe due to frequent ondeck handling.

Thanks for the comments.

I found the New England instruction but was left a bit confused until I
printed it out. Seems their direction doesn't display correctly in my
browser.

The printed instruction will be added to my onboard splice file.

Thanks.

One thing that I noticed in my limited experience with Spectra, was that I
have difficulty cutting it with a Hot Knife and it is near impossible to
weld or seal the ends. Even a small piece of masking tape doesn't work very
well. Kinda like putting tape on teflon.

I'm wondering if the end sealing of the rope yarns shouldn't be done with
some glue, etc.

Any comments.

Hi Steve,

Spectra melts very nicely, sounds like either the line is not Spectra or has
some salt on it. Once you've used any high tech line at sea, it
becomes -very- difficult to splice and/or melt. You can try to rinse the
line in fresh water and drying, but I haven't had much luck in the past.
Incidently, Kevlar and Technora -do not- melt (they singe or burn), and the
only way to properly finish the ends of the line are by whipping or a tuck.

I looked and looked on neropes but I couldn't find squat on brummel.
Where did I go wrong?
