I've a friend in my YC that has a 322. it's a stiff boat. 3ft draft with wing keel.. don't think you could call it a blue water boat though.
I second that comment. We owned a 322 for about 12 years and it did VERY well in high wind because it is so stiff. It also has an inordinately short rig. That helps, and we liked it.
Heavy sea motion is another matter. When the relatively flat bottom of the 322 hits the water it pounds
the water. The result is very uncomfortable.
In my opinion, sea boats should be shaped like this: A Cape dory 25D
All things considered, though, the 322 is a fine boat.
