What is a HIN on a boat bill of sale?
The Hull Identification Number is a 12-character code unique to the boat, similar to a VIN on a car. It is required to register the vessel and should be copied exactly.
Do I need a separate bill of sale for the boat trailer and motor?
The motor is usually described on the boat bill of sale. A trailer often has its own VIN and may need its own bill of sale and registration — use our trailer bill of sale for that.
Is a bill of sale proof of ownership?
Generally no. For titled property like a car or boat, the title is what proves ownership. A bill of sale proves that a sale happened and records the price, date, and terms — it supports the title transfer but does not replace it. For untitled property (furniture, equipment, electronics), the signed bill of sale is usually the main proof of ownership.
