I was watching a bit of the Americas Cup coverage, and I noticed that the cup boats look like the hull shape is very simmilar to Bolger's wall-sided sharpie designs. I haven't seen any lines drawings of the Cup boats, but from the pictures I've seen, they look pretty much flat bottomed and wall sided, the only difference between those and Bolger's sharpies is the radius at the chine. I'll bet that the curve of the sides matches the bottom curve also. I've also noticed the flatt-top main sail, looks like a modernized gaff rig. That keel looks totally impractical for a cruising boat, however.
