John,

I set mine up so I had a "fairly" balanced boat down wind, but this gave a bit of weather helm upwind. I'll happily measure my mast rake and let you have it as a starting point - I don't know if JohnP makes the shrouds/forstay the same lengths every time, but I have the pin in the 6th hole down from the top on the shroud plates. BUT I am thinking of moving the mast a little more upright to counter the weather helm.
