What's the temperature have to do with anything? I know what you're
gonna say. You're gonna say volume decreases with temperature decrease
and vice versa. But does that not also hold true for the measuring
container?
It's the same thought process those dummies who say to loosen the
standing rigging for the winter storage period because the stays and
shrouds shrink with the cold. But, I suppose they think the aluminum
mast doesn't also shrink? Duh!
Ya gotta think outta the box, man.

Oh dear,
I am going to regret this: the troll's not only wrong,
but ugly about it too!

Gas expands in volume 950 ppm per deg C
So it's important to sell by mass (which is invariant) or
by volume at a set temperature.

It's not a lot in a tank of gas (so much for filling up in the cold
pre-dawn) but it mounts up if you sell by the million barrels.

Steel and aluminum expand at different rates:
the linear rates are Steel 12 ppm /degC, Aluminum 24 ppm /degC

So the time to ease the stays is when leaving a boat in warming
weather, if at all. A sample 50 ft mast might need two or three
turns easing on each rigging screw for 30 degrees C temp rise. But
more care is needed with plastic rigging.
That can really change with temperature.

A simple example: You decide you want to buy a barrel of crude oil,
the price is in the newspaper every day, right? Now tell me what a
barrel of oil is? Right off the top of my head I can think of several
different sizes of barrels, 55 gal., 44gal., 200 Ltrs., etc.

Bad example. The petroleum barrel has been 42 gallons since they used
old herring barrels to haul crude in horse drawn wagons. It is a
recognized item in the list of internationally accepted weights and
measures. My calculator has it as 42 gal per bbl. By the way, a 55 gal
drum holds that much so that you get 50 gal liquid capacity plus the
necessary expansion space. So it's actually a round number.

No, good example as my company worked for just about every
international oil company in Indonesia and every one of their
contracts defines a "barrel" in the preamble to the contract. By the
way is not 42 US gallons, it is 42 US gallons at 60 degrees F at sea
level. :-)

Willie-boy I got admire you. you are the perfect example of the old
adage that, "fools rush in where wise men fear to tread".

A "barrel of oil" is a standard of volume measurement used in the Oil
Industry. Just like gallon or liters, and since the volume of most
liquids change with temperature or pressure the temperature of the
liquid and pressure the liquid it is exposed to is specified.

A standard contract definition will be something like "a barrel" shall
be defined as 42 US gallons at 62 degrees F, at sea level.

In reference to rigging changes at different temperatures they
certainly do change in length with changes in temperatures. You can
look up the coefficient of expansion of aluminum and stainless on the
web or in most engineering handbooks. Of course, in winter the colder
temperatures will cause the spars and rigging to contract and the
aluminum mast will contract more then the stainless rigging so your
comments on the necessity to loosen rigging for temperature change in
winter is correct.

I'd hate anyone to take a Troll's sneer at face value like that.
I'm thinking of a race boat with a carbon fiber composite mast.
This material can have an extremely low thermal coefficient - as low
as 1 ppm /degC.

Most rigging would shrink more in Winter (but a few would expand when
chilled, wouldn'tcha know?)

Well, if you are designing a high tech racing boat why not use high
tech synthetic rope for rigging. some of it is stronger then stainless
cable and nearly zero stretch.

As far as your latin terms they are seldom if ever used in written
contracts. In fact the only non English term I have commonly seen in
contracts is "force majeure" and the term is always followed by a
section describing every possible action that may be considered force
majeure.

But why complain about technical terms used in a specific trade?
Sailors use them all the time and term anyone who doesn't understand
them as "lubbers", one of your favorite terms.

But talking about strange terms used in print is your term
"Bwaaahahahahahahah!" intended to mimic the sound of a belch? Or
breaking wind?

Quite right, Bruce. But you must understand that Neal's perception of what
lawyers do is more than a little myopic. It seems to derive almost
entirely
from watching a great deal of Perry Mason and from some rather pathetic
attempts to act as his own lawyer in traffic court.


Or, perhaps he had a bad experience in another venue.

I can visualize various combinations of rig and mast , it's true. But
a zero-stretch line does not always imply a zero thermal coefficient
line, I don't believe.

There is a new rigging material out which is exactly that: high-tech
synthetic rope with a protective covering. Don't recall the name of it, but
it's very lightweight and exceptionally strong. At least in theory. Jury's
still out on how it works in the real world.

True, but I suspect that in practice the difference will be negligible
enough that it can be ignored on "normal" boats.

If you are talking all out racing boats then I suspect that some of
them may slack off the rigging at the end of each race regardless of
what material the mast and rigging is.
