Read with interest recently that 505's (mono dinghy) are building boats with a centreboard case that allows the board to rotate side to side... so when sailing on either tack, it will produce greater lift to windward. Haven't heard or read any comment on how effective it is, or how they stop it pivoting when they're reaching, etc. I wonder of our greater speed on cats would just produce too much drag for this idea to be of any use?
