actually there are three classes: dinghies, multis and monos... To put more gas in the fire <img src="http://www.catsailor.com/forums/images/graemlins/cool.gif" alt="" />: If you can sail dinghies you can sail all of them, if you sail cats, you still can sail monos, if you sail only monos, well... you play better golf.

Some mono sailors will use this as a proof that cats aren't safe...
