I might as well sound off too...
My wife and I are weekend cruisers primarily, and the cabin layout of the 310 suits us perfectly (forward stateroom etc.). When I want to race, I crew on my brother-in-law's C&C99. I am guessing with the introduction of the 309, that Catalina wants to go after more of a cruiser/racer market (H33, Beneteau, C&C99 etc.), and that is fine with me. We love our 310, and with all of the options and extra's that we have on the boat, we probably could have saved maybe $10,000.00, but would not have the cabin comfort. Boats are very individual, and I don't doubt that the 309 could be a big seller for Catalina, but I am very happy with the choice that we made.
