Having never sailed monohulls, I can't say whether is sails more like a monohull or a cat. My experience, however is that whenever I race my corsair I am at a yacht club with monohulls participating on the same race course. Its rare that a beach cat is even within sight and which brings me to my point, "out of sight, out of mind".
I agree this site is much more user friendly! The Corsair 28 Association also has a forum but it is not as easy to use as Yahoo and gets used even less than this site. Only thing that Yahoo has is that a lot of non racers are actively using it. You can find the Yahoo site when you search Corsair in a browser. I have not seen this site come up in a similar search.
