When considering a deviation from the tested norm in lifeline materials, we
should ask ourselves "Do you feel lucky today?".

You are correct that ORC regulations do not incorporate high tech lines used
as lifelines. However, there are ongoing discussions in some PHRF areas as
to whether they should be legalized.

As an aside, Johnson Marine Hardware is making lifeline terminals designed
for high tech line. IMHO, if used with proper care, I would have no problem
with the application. It could be considered a safety improvement.

IIRC, the folks who regulate lifeline specs for the offshore racing set
are not
yet ready for materials other than stainless wire. Lifelines certainly
are an
application that has lots of people thinking about it. I wouldn't do my
own
engineering here, but wait for a change in practices to evolve and be
thoroughly
tested.

Sailrite has some fairly heavy closed ss thimbles. You might also try
Howe&Bainbridge, supplier to sailmakers.

Good point.
I may end up w/ss for this. I want to replace my lifelines with Amsteel.

I recollect learning that only cast thimbles or heavy galvanized
thimbles
were
generally stiff enough not to deform when loaded to a nylon or dacron
rope's
full safe working load. Stainless ones were second place and plastic
a
distant
third. Ask a competent rigger before using a plastic thimble in a
line
that's
to carrry any significant load.

Garland,
I've seen them quite consistently at West Marine {all over}. I would
try
them, first. Other places to 'look' are Jamestown Distributors
{Rhode
Island}, Hamilton Marine {Searsport, Maine - for REAL, 'Workin'
Stuff'},
and
Defender Industries {Conn}.

My only caveat is, I'm not sure about the 'larger' sizes - 1/2 in
line
and
up. I know I used white ones for my 3/8in and 1/2in mooring
pennants -
got
them at the Philly West Marine store.

Regards & Good Luck,

Ha, I was a little slow to get that one!
I always used ss until I saw what it does to galvanized chain.
I had never seen a black plastic one until a few hours ago! A
friend
had
bought an anchor line on ebay, and I noticed it in his truck. Only
id
was
Taiwan, but was a nice thimble w/ straps.

Doing a lot of sewing?

Why not SS? I don't think I've ever seen a black plastic one,
but it
would
be a good idea. Would be cheaper for the mfg's as well.

Are these available? It's easy to find white or translucent
thimbles,
but
uv
eats them up so badly.
TIA
