It’s going to be hard to beat the boats captain nat came up with, or the other guy’s that designed those j’s. They were all powerhitters of the Yachting world. The rule beater mentioned above would not work. Correct me if I’m wrong, but the universal rule then in place did not measure overall length, just waterline length. That’s why they have those long overhangs, it increases the waterline length of a boat under heel. And it looks purty!
