I've seen open ones in bronze and solid-body ones in aluminum and bronze, if
memory serves.

OK, that's a new term to me. What metal is a "cast" thimble made from?

For the smaller sizes, i've seen cast thimbles which were solid and bored
3/8"
or so for a shackle pin. I think I got 'em from sailmakers.

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

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.

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.

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.

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

Perhaps, but rule makers are pretty conservative types. I'd rather have a
synthetic line that I can see than a vinyl coated s.s. wire that could be
rusting away sight unseen. It's actually cheaper AND lighter AND stronger
for spectra 1/4" v.s. 3/16" s.s. wire. I like having higher safety factors
that the line gives me.

My email connection has been AWOL, so I've just read these messages.
Since I don't race--officially anyway--I wouldn't hesitate to use one of
these hi tech lines. For one thing, I want to secure each end w/ easy to
release lashings rather than a turnbuckle.
Not that it is a likely occurance, but should your boat be hit by lightning,
metal lifelines are less friendly.
To be sure, what they use is a lot larger than what I have in mind, but I
understand the USN uses synthetic line for lifelines
