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.

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.

Going back at least ten years a Farr 40-something, named Millennium,
was using some sort of high strength synthetic for running back stays.
Of course, these really only have to be low stretch but it shows a
trend.
