Hi John, reading through your earlier comments sounds like the 255 would be a perfect boat for your needs. You've had twins before, you aren't planning on trailering a boat, and as you've now seen first hand, it rides awesome in the chop (an important benefit in the waters around here!).
Personally, I was attracted to the 22 for it's size (biggest C-dory that will fit in my driveway), and ease of trailering (it tows great!). Ironically, it turns out that I'm not even keeping the boat in my driveway or on a trailer, so neither of those points even matter, and now a small part of me dreams about how nice a 25 or 255 would have been! Fortunately, both are way out of my price range (at least for new boats) so it's a moot point, and as a solo cruiser a 22 really is a great size. The point being, since you aren't planning on trailering it seems the Tom Cat would be an ideal boat, as it's increased size and weight for trailering seem to be the main down-side for those who trailer.
I think your question about spray in the cockpit was an excellent question related to the TomCat, given the other recent thread regarding excessive spray from certain generations of outboard brackets used on the 255, and since a cat is likely different design from your previous boats. As others have said, all small boats will get a fair amount of spray in the cockpit if it's windy enough (it doesn't take much wind either, just a bit of a cross wind to blow the spray from the bow right back into the cockpit).
I don't see your name on the sign-up list but since you are local, hope we get to meet at the Seattle Boat Show...when I talked to Marty at Master Marine about a month ago they were planning on having a Tomcat as well as a 25 Cruiser at the boat show (in addition to perhaps a 22 and 23), although not sure if that is still their plan.
