Thanks Bob, I'll have more time to look at it next weekend. I hope you are correct. IF you can remember next time couod you maybe take a couple of pictures and throw them into a folder in the photo section. I'd love to see how you did it Keith I wa not ignoring you, VMG? I can't say yess as I normally don't plow upwind in 20 knots iwth a 155 up and we ended up sheeting to the Rails with a 130% But on sunday when we had much less breeze, I was actually able to sail inside of the windex reference tabs instead of outside (no ... i only pinched for a while to see how high we could go!! )... So VMG? not sure, but better pointing YES! And I can now say the North can still cut a good looking Paneled jib wiht out having to go to a Triadial! I'm satisfied!
