Hello! We are looking to buy a semi-FAST boat to race in the river/ Gulf of Mexico by Fort Myers, FL. Have set my MAX draft at 4'6". have found some interesting used boats with retractable keels (and the 32s5 has a fixed 4'5" keel). any ideas which will be the fastest upwind in < 10 K ? our winds in river are not usually too high. Any advise appreciated. Thanks so much, Captain Diane
