shroud tension for oversize wire

[asdf777]

Hi,

Official displacement is 8600 lbs. When loaded, probably 9600 lbs. Balast is 3600 lbs. Capsize ratio - 1.92.

Not sure about righting moment. Is there a way to calculate it? I've never done an incline test. Can I perform it without special equipment?

What I meant to say about "sagging in waves" is that unless the tension on the lower shrouds is less than 750 lbs or so (or maybe 700 lbs), those lower shrouds on the leeward side will momentarily sag/loosen/slacken after the boat goes down the wave and hits the trough. They swing freely for a moment, thus when going back to tension, there is probably a high/shock load on the chainplates and through mast bolts.

Given that the original wire size is 3/16", I'm worried that 15% of the breaking strength of 7/32" wire is ~25% of the 3/16 breaking strength, which is a high load for the 35 year old through mast bolt holding the double tang. Or maybe not? What do you think?



Hopefully it makes sense,
Gleb
