Subject: RE: [worldcruising] Rigging Tension
From: Ray Thackeray (rayt@XXX.XXX)

Perhaps I was a little inflammatory by saying "25%" of breaking strain
for rigging tension was "not useful information". But after over 21,000
nautical miles of sailing, I think I at least have a little experience
(not as much as some...).
However, the bottom line is that for most people it is impossible to
find out a) what the breaking strain is for their rig - is it for
terminals, for wire, or what? and b) how the hell do you measure it?
My boat is a 51' Offshore Garden Ketch - and after 10 years of
ownership, I have never found anything in any manual, documentation or
other general reading to tell me what the breaking strain of my own rig
is. On top of that, I know of no product I can buy that would give me
that measurement.
Finally, my rig hasn't fallen overboard after over 20 years of sailing
and no replacement!
The usual advice, of course, is to replace all the wire and terminals
every 10 years. Frankly, I think that's too general - I would rather
inspect the rig and look for cracks (at least, in stainless steel) or
deformities (in galvanised steel). But in a well rigged vessel sailed
conservatively, I have found that wire and terminals can last well above
the usual advice given by boat yards - who want to charge you $10K for a
re-rig.

Yeah, well...
Book learnin' is one thing, but I sure wouldn't want
to be sailing any vessel with rigging tensioned anywhere
near 25% of breaking strength!
Sometimes some folks know more than _most people_
simply from experience.
Lighten up, Karl
