Dating boats by hull number
Did you ever wonder what that strange series of letters and numbers on the transom of your boat are.
Well, if you have taken the Nautical Know How course you know they are Hull Identification Numbers (HIN) and that they are required. All boats manufactured or imported on or after November 1, 1972 must bear a HIN.
The HIN is a 12 character serial number that uniquely identifies your boat. It enables manufacturers to clearly identify for boat owners the boats that are involved in a defect notification and recall campaign.
A HIN is not the same as a State registration number, which may be required to be displayed on the bow of your boat.
Its location may vary slightly depending on the type of boat -- whether it has a transom or not, and if it has more than one hull.
The last four characters determine the model and certification year of the boat.
Finding the hull identification number, or HIN, on your boat is a simple matter of walking to the right spot.
The HIN isn't the state-issued number emblazoned on your boat's bow.
As of November 1, 1972, all boats in use have been given a Hull Identification Number.
The Hull Identification Number (HIN) is a Federal requirement.
