HR 2550 may make it illegal to wash your deck
On Sun, 16 Sep 2007 13:08:32 -0400, a troll wrote:
a "barrel"... is not 42 US gallons, it is 42 US gallons at 60 degrees F at sea level. :-) 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. Wilbur Hubbard 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.

In reference to rigging changes at different temperatures they certainly do change in length with changes in temperatures. ... 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. Bruce in Bangkok 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?) Brian W 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.

Wilbur Hubbard 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? Bruce in Bangkok (brucepaigeATgmailDOTcom) |

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. -- "j" ganz @@ www.sailnow.com |

Bruce in Bangkok (brucepaigeATgmailDOTcom) 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. Regards Brian W 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. |

Regards Brian W 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.
