I second Jakes comments on the F18 being included. I've sailed the G2P race over 15 times on monos and my Reynolds 33. I've also done the Tybee 500 - 7 times on F18's and N20's. Also add in two Texas 300's, on N20, and F20 (btw the texas 300 rhumb line takes us 30+ miles offshore at times.
The F18 is fully capable of doing the G2P, in fact it's a cake walk compared to the first two legs of the GT300, and the last leg of the T500.
I would be willing to put my money where my mouth is and do it on the F18 next year - officially or "unofficially"...
