My question is, for those who have a cat 22 or similar, how does she sail?
My first boat was a C22. In light winds it sails like any other keel boat. It relys a bit on hull form stability, so, in heavy air it starts sailing more like a dinghy. It is possible to capsize a C22 if you get supprised by a big gust. Normally it will just round-up rather than go over, but, if it does go over you can get significant down flooding from lockers, the main hatch, and the gas locker vents (if a port knockdown). I sold my C22 to a guy who did just that. Got knocked down, and sank the boat. In higher wind or gusty conditions, I would keep the main sheet uncleated, and sheet in hand. You can also take the precaution of putting hatch boards in, latching cockpit lockers, and maybe even stuffing a sock in vents.
