Using this example hull number, you can learn more about your boat from the hull number:
BIYB – MANUFACTURERS CODE
23 – BOAT SERIAL NUMBER
CU – MODEL REFERENCE NUMBER
F5 – MONTH AND YEAR THE BOAT WAS MADE
06 – MODEL YEAR OF THE BOAT
i.e. the “C506” shows that the boat was made in “F” which is June, “5” which is year 2005, but is a 2006 production model year.
Please note this applies to most boat manufacturers since 1984, however, there are exceptions.
