A simple question to the group.

Does anyone have the correct tension for the standing rigging on a 54?

Hi Denis,
You'll want 15% of breaking strength, which, of course, is dependent on the size of the stay. You can google it, or a tension meter usually has the reference numbers on it.  Or just make them "Amel tight".

Do you know if these figures apply to Santorin and SM as well as the 54?

Hi Ian,
Martin's figures are just the arithmetic for various wire sizes to get to 15% or to 20% of breaking strength, which, as he pointed out is what Selden recommends (15%). The 15% or 20% applies to all wire sizes and it doesn't matter what boat the wire is on. Do note that our SN's have some 6mm stays (marocain and artimon pataras) which has a 6351 pound breaking strength, so to be at 15%, the arithmetic gives you 950 pounds of tension.

You could certainly kick it up to the 20% figures Marin's guy Franck also shows to get to "Amel tight" although I've kept my mizzen backs at 15%. With new rigging you might want to go to the 20% initially to account for the stretch that will occur after some sailing. Nance and Underwood in Ft Lauderdale do an initial tune to 15%, btw. None of this is "rocket science".

Hi Ian,
I fully agree with Craig. 

You will find a lot of information worth to know here: https://support.seldenmast.com/files/595-540-E.pdf

Thanks guys. Having new rigging in the new new year. Just trying to get the rigger tuned in to Amel standard.
