Boat Loan Terms for $250k to $1M Boats: Down Payment and Length
Model 15% versus 20% down on a $650,000 sportfish and see how 15-year versus 20-year terms change monthly payment and total interest paid.

Down payment tiers by price band
$250,000–$500,000 boats commonly see 15% minimum down ($37,500 on $250,000) from prime marine lenders; $500,000–$1M+ often starts at 20% ($130,000 on $650,000).
Older hulls (20+ years) may require 25% down on $400,000 purchase ($100,000)—reducing financed amount to $300,000 improves LTV for survey value shortfalls.
Trade-in equity counts as down payment only when title free and clear—$80,000 trade plus $50,000 cash equals $130,000 down on $650,000 deal.
Tax and registration fees usually not financeable—budget $15,000–$35,000 cash outside loan on Florida/documented vessels.
Term length and payment math
$650,000 purchase with 20% down finances $520,000 at 7.25% simple interest: 180-month payment ≈ $4,730; 240-month ≈ $4,050—$680 monthly relief.
Total interest 180-month ≈ $331,000; 240-month ≈ $452,000—$121,000 extra interest if you never prepay.
If actual hold period 5 years, compare 5-year cumulative interest: shorter term often wins despite higher payment.
Balloon structures rare post-2008—avoid residual balloons unless business use with documented balloon payoff plan.
LTV, survey, and holding period
Lender LTV 80% of survey value on $600,000 ask with $560,000 survey caps loan at $448,000—need $152,000 down plus fees, not 15%.
Five-year hold with 240-month note: after 60 payments you still owe ~$470,000 on $520,000 start—ensure resale market supports equity.
New boat 20% down plus 15-year term aligns warranty window with payment—engines covered while payment highest.
Document age-based amortization caps—some lenders max 15 years on boats over 20 model years regardless of buyer preference for 20-year payment.
