I have heeled my 192, which is the smaller sister of the 222, so far that water has come in over the cockpit coaming. In order to heel that far, you must have a great gust while close hauled, and you must deliberately steer the boat aggressively so that she doesn't round up. Needless to say, this is not optimal from a sailing standpoint. On other days like this, I have sailed with reefed main alone without jib. Some boats will heel far enough that the rudder breaks free of the water, and they round up automatically. Not sure I want mine to heel more than I have, to find the point where she automatically rounds up. There would be a lot of water in the cockpit in that case!
You'll have to recognize that this is a coastal cruising/daysailing boat for mostly protected water. Which, is pretty much most boats in this size and functional range. Unless you get a small bluewater boat like a Flicka. When the wind is gusting to 30 knots, it's best to be headed in with reduced sail, or not go out in those conditions.
All that being said, having grown up an unballasted dinghy sailor, it did take me a season or so to get over concern about heeling, and to learn to trust the ballast. Perhaps that big heeling day, I trusted the ballast too much?
The other weekend she was just heeling enough to wash the toe rails, and not the coaming. I moved up to sitting on top of the coaming, which is perfectly sculpted and angled for this. I was still washing the coaming "sitting out" like that, so I hove-to and tucked in my reef. Things were a bit more calm after that.
