Boats manufactured or imported on or after August 1, 1984 must have a 12 character Hull Identification Number that uniquely identifies each boat.
The first three characters of the HIN are a MIC (Manufacturer Identification Code) assigned by the Coast Guard to the manufacturer or the person importing the boat (“BEY"
in the case of Beneteau).
Characters four through eight are a serial
number assigned by the manufacturer.
The last four characters indicate the month* and year the boat was built, and the model year.
* A=JAN, B=Feb, C=March ... L=Dec
