Thin intermdiate stay

Seems to indicate less load on the intermediates, but not clear "how much" less.
Did you make a typo, or are you really going with a big jump from 7mm to 3/8 (which is 9.5mm or 10mm)?

I meant 5/16th. I recently replaced my uppers (survey found a cracked swage) and the rigger suggested using SAE turnbuckles with 5/16 wire (and a special order metric toggle for the chainplate).

Hello,
Classical load distribution calls for the V2's and D2's being the same size (See the Apprentice, but on most boats, even cutters, more goes to the upper panel, thus the smaller D2. Note that a combination of 5/16" and 9/32" is also an option, and would preserve the existing pin sizes. The question, as always, is "what is the load?" Since this is a sloop, the only lateral load at this height comes from the mains'l. So if there are no signs of accelerated fatigue in the old wire, stay with 1/4".
Fair leads,

Appreciate your input Brion. Your comment re 9/32 preserving the existing pin sizes is a very good point.
Thanks.
