Why not Spectra ?

[Jak Mang]

Has anyone tried Spectra for bobstays? Is there any data on long term exposure to saltwater?

I'm also interested in tensioning alternatives to deadeyes for this use. Brion mentioned a horror story in a class about turnbuckle below the water line on a bobstay. Obviously, the turnbuckle should have been on the upper end. This lead to a hint that perhaps the turnbuckle could/should be eliminated all together. Is there a way to pre-calculate tension on fixed-length gangs and install them under load? This would save a lot of hardware and weight.

I apologise for the novice questions. I'm trying to immerse myself in the technology.

Thanks,
