could you change that by just changing the location of the sheet block? Would pull more evenly on the leech and pull the top in a little more.
I think you might need to do this as well.
Looking at (what we can see of) the exhaust profile, the leach does look like it's a little open; Putting a dart into the luff will also close the leach slightly, but maybe not enough.
John, I assume you have enough room inthe sail measurement rules to make the mod?
