One nice feature with our boat is that the centerboard allows us to control the amount of weather helm (I guess technically what we can do is move the center of lateral resistance when we drop the board). Absolutely essential to get maximum performance about of the Monitor windvane. I guess w/o the c/b we would have to do the things suggested here to reduce our helm when the wind pipes up.
Finished the circumnavigation in early February in Grenada. Have to work on a book project for the next several months so the boat will be waiting for next year.
