Whoa
Hi again,
Way back before things wandered off into cost comparisons, we were looking at load vs wire sizes. To get a 25,000ft.lb. RM at 30 degrees, you would have a 25ft or so waterline.Is that the case? To get about 8,000lb required strength for the uppers, assuming a safety factor of 2.7 or so, the half-beam to the chainplates would have to be over 5ft. Is this so? If it is, staying with wire that size is not in the interest of the boat, nor of your wallet. If you arrived at different numbers, perhaps you could describe how.
Many wire size numbers these days are for the rated strength of 316, hence the discrepancy you saw. 5/16" is still way too big.
I don't know why Hayn wouldn't give you a break number for their 1/2" turnbuckles. Navtec shows 14,700 for theirs, which I am sure is conservative. Also sure that Hayn's are at least as strong.
As for configuration, shouldn't be any useful difference in strength. But Hayn's bends are noticeably fairer than others'
Fair leads,
Brion Toss
