According to my paper work the hull identification number is “CTYN0773M77L”. What does that mean?
The hull numbering, as required by the USCG, contains 12 characters; 3 groups of four. The first four are manufacturer and size, i.e. CTY for Catalina Yachts and “N” for 30, “L’ for 27, etc. The next four are the serial number of the boat (only the C22 exceeded the four spaces allowed with 16000 boats built-we dropped the “1” at the front). The last four are the year of manufacture and/or model year. This coding changed over the years.
