View Full Version : ST137 (2006) max sail size with stock fin?

I was just out today -and because wind was low light and my FT138 still "offline"- I stuck a 9.5 onto it and voila, it worked surprisingly well. Still no match for the FT138 though (neither speed, nor angle, early planing "almost"). How large a sail can one really comfortably put on to it (maybe with a slightly larger fin) to get the planing threshold down a bit further?
