I spent many years on a Nacra 5.7, one of the faster sail boats that size. My problems with the mono hulls of that size are the weight. My dad's compaq 19' is about 2500lbs alone. The the trailer to hold that and any other thing you want to take with you. If you can sleep on it, you start to take camping weekends. Then you almost need full size trucks to tow it, and last a long time. Maybe a trimaran would be a good thing to look into....
