Where must the Hull Serial Number be located on a pleasure craft?

The Hull Serial Number (HSN), also known as the Hull Identification Number (HIN), must be located on the exterior of the pleasure craft, typically on the transom (the rear part of the boat) or on the starboard side, within the upper quarter of the hull. It should be permanently affixed and easily readable, often stamped or molded into the hull material. The HIN is usually a 12-character alphanumeric code that identifies the boat's manufacturer, model, and production year.
