Enjoy!!!!
I too have a ODay 25. I also race with a friend on a Catalina 25 in a Catalina Club Series. I too prefer the shoal draft/centerboard of the ODay to the Catalina's swing keel. We sail the Great Lakes and the swing keel will bounce in waves and heavy weather. The swing keel system also takes added maintenace.The side decks of the ODay make moving around the deck a breeeze. The wider dside decks make a narrower cabin roof. This makes the interior seem smaller, but you spend the majority of your time outside the boat, not inside. The pop-top on the Catalina is just another thing to break, (am I opinionated or what?) The berths on the ODay are wider than the Catalina's, so they are more comfortable to sleep on when you are below. Obviously, you can see I like my ODay. We've never raced the two boats side to side. I think the Catalina would be faster and point a bit higher. The ODAY 25 does have one weak point,the tiller. It works fine, but has been known to break.
