The Moesley and Potter 20's are 19' and change whereas the post-Potter 20's were stretched to 20' 4" or so. The current 21' is actually 20' 5" and is more or less a 23' with a foot and a half chopped off the back. It's a more substantial boat than the 20'. The Seavette uses the 23' hull shared with the CC, Sceptre and Savage models. Perhaps you are referring to the Seafari which uses the same hull as the 20' CC.
Confused yet?
