Boat loan basics

Boat loans are often longer than car loans (10–20 years for larger boats) and lenders commonly ask for 10–20% down. A longer term lowers the payment but increases total interest. Budget for ownership costs too: insurance, fuel, slip or storage, winterizing and maintenance are often estimated at around 10% of the boat’s value per year.

Frequently asked questions

How long can you finance a boat?

Terms of 10–20 years are common for larger boats; smaller loans are often shorter.
