Duh . . . that makes perfect sense. So I'm assuming it's a bit of an art form in setting the on-shore prebend. You want enough to fit the natural fit of the sail, but you want to leave enough for downhaul and mainsheet control to deal with all kinds of conditions.

Makes perfect sense. Perhaps 2" spreader rake is right?

At any rate, I think I'm going to bend it back a little more as a start. I'm not getting the performance out of the sail (the top 1/3rd in particular). It always seems a little hooked and I can never flatten that area (even with loose battens).

I'll post what I learn.
