What special care should you take with your hull identification number?

The hull identification number (HIN) is a unique identifier for your boat, similar to a vehicle's VIN. It's essential to keep this number secure and visible, as it is used for registration, insurance, and tracking purposes. Ensure the HIN is not altered or obscured, and maintain a record of it in a safe place. Additionally, when selling the boat, be prepared to provide the HIN to potential buyers for verification.
