On the USCG site you will no longer find any reference to what is meant by "small craft." It used to be 65 feet and under back in the day. Now it more or less says if you think you aren't capable of handling the weather, don't go out.
Also, the NWS issues small craft advisories, not the CG, and each NWS station around the U.S. has its own definition of what determines a small craft advisory (each has different wind speed, wave height, etc.)
