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. 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. Take a look at the pendulum of a grandfather clock. They cleverly arrange brass and steel so that the assembly has a zero temperature coefficient. If the rigging stays the same length while the aluminum mast increases in length, the rig will get tighter. Not what you want. Casady |
