it takes a lot of skill to race a monohull well just as it takes a lot of skill to sail a cat well. I race on a monohull (J29) and the skipper used to race cats for something like 15-20 years. When he got a little too old to continue putting up the mast (his wife as well) he bought a monohull and still has a great time racing it. However, when I tell him I can't crew for him because I am racing my cat he often says that he'd rather be racing a cat also!
