Need to know what brand boat you just bought? Well, if there is an ID number on the hull - you're in luck!
The first three letters of the 12-digits of the 'HIN' or USCG Hull Identification Number identifies the manufacturer ... provided your hull wears an embossed, molded, stamped/riveted, and/or printed number on the upper right side of the transom.

Be aware that as older manufacturers may have long gone out of business ... it is quite possible that the HIN# has been re-issued to a new boat brand.
