Thanks Brion! That clears it up nicely. I already have some loads estimated relative to righting moment, and will work from those numbers, rather than "rules of thumb".
My bowsprit is a new addition, so i have a blank canvas to work with, and at least am not being confronted with fitting the right rigging to the wrong tangs; I'll fabricate the headgear bits to fit the loads.
Quite unlike the rest of the old swaged rig; all 9/32" wire, but with a mix of tang and clevis sizes down to 7/16"... Just going ahead and making new tangs and chainplates properly sized for 1/2" pins all round; enough evidence of corrosion on some of them to warrant replacing all of them anyways.
