What is the minimum down payment for a boat loan?

Most marine lenders require 10-20% down on a boat loan. Some credit unions and specialty lenders offer 0-10% down programs for well-qualified borrowers, but these carry higher rates. A 20% down payment gives you the widest lender choice and the best rates. On a $40,000 boat, expect to put $4,000-$8,000 down at a minimum.
