Tensioning standing rigging

[Brion Toss]

Hi again,
Without knowing how the old gang behaved, we need to start at zero, so first assume that there was a lot of constructional stretch in the new, 7x19 wire, and further assume that it might not be completely sailed out of the wire. If this wire has an IWRC core, you'll see about an inch of constructional stretch in thirty feet. If it is a regular core, there'll be even more. So the first thing is to determine what the wire is, so you'll know when it has stabilized.
Next, we know that the new wire is going to have more working (recoverable) stretch more than the old, both because stainless is weaker, and thus more elastic, than galvanized, and because of the construction, which is literally springier. Tune can compensate for some of this, as can massive wire size, which lowers the relative load. We can deal with thal later, but first, find out about that core, so we can run some numbers. Meanwhile, did you track how much you've taken up on the turnbuckles?
Fair leads,
Brion Toss
