What they said; also: Your centerboards are not terribly efficient, and your rudders are small. The hull design, however, is terrific for cutting thru chop. The key to making decent vmg upwind is to sail FAST; 8-10 knots is good. The daggerboard boats will outpoint you, but only by 5 or 10 degrees; however, you'll be going noticeably faster thru the water. I try to keep far enough off the wind to keep my jib just pulling. Have fun!
