Did a quick google search using search terms "Hull Identification Number ZZZ" and came up with many sites describing how to decipher the HIN, each of which used ZZZ as a generic for the first 3 letters of the HIN, which identifies the manufacturer. Also, ran across a reference to a USCG searchable database of HIN's. Give it a try and maybe you will find something:
