Rough weather seperates real boats from bad boats...
It is pretty silly to think that only "real boats" can handle 45 knot winds and large breaking waves. A sailboat, much like any other vehicle, is designed for a particular purpose.
Is a Porsche 911 a "bad" vehicle because it can't handle icy mountain roads? Is a Range Rover a "bad" vehicle because it turns in lousy track times?
It is the same with sailboats. What the "best" boat is depends on where and how it is used. A great blue water cruiser would be a "bad" boat for inland racing. Your comment is like calling a screw driver a "bad" tool because it can't drive nails.
