boat bill of sale A boat bill of sale is a legally binding contract that outlines the specifics of a vessel transaction. It functions as an official receipt, confirming that the seller has transferred ownership to the buyer. Beyond just documenting payment, it provides a clear record of the boat’s details, including its name, registration number, make, model, year, and hull identification number (HIN).
