You can finance a boat through a bank, a credit union, a marine lending specialist, an online lender, or the dealership where you’re buying. Which one makes sense depends on the boat’s price and age, your credit profile, and whether you want the vessel pledged as collateral. Secured boat loans generally run 4 to 8 percent; unsecured personal loans used to buy a boat run roughly 8 to 15 percent or higher. Most lenders want a credit score of at least 650 and a down payment of 10 to 30 percent, with the exact numbers shifting by lender type, loan size, and the age of the hull.
Banks and Credit Unions
Banks are where most buyers start. If you already have a checking or savings relationship, you may qualify for a rate discount or faster approval. Banks typically write secured boat loans with the vessel as collateral, which keeps the rate well below any unsecured alternative. In exchange, underwriting is stricter: clean credit, verifiable income, and a real down payment.
Credit unions deserve a separate look. Because they’re member-owned nonprofits, they often undercut bank rates by a noticeable margin. Some credit unions with a boating focus offer terms as long as 180 months on qualifying vessels. Membership rules vary, and many have broadened eligibility well beyond their original employer or geographic base, so check even if you don’t think you qualify.
Whichever lender you use, the Truth in Lending Act requires disclosure of the annual percentage rate, total finance charges, and repayment terms before you sign, so you can compare offers on equal footing.1Office of the Law Revision Counsel. 15 USC 1601 – Congressional Findings and Declaration of Purpose Ask for the APR, not just the interest rate, and compare across lenders using that number.
Marine Lending Specialists
Specialist lenders write boat and yacht loans and nothing else. That focus matters because their underwriters understand hull depreciation curves, seasonal resale values, and the quirks of marine collateral in a way a generalist bank officer does not. For older vessels or unusual hull types, that expertise can be the difference between approval and denial.
Many of these lenders belong to the National Marine Lenders Association, which promotes sound lending practices across the recreational boating industry.2National Marine Lenders Association. National Marine Lenders Association Home Specialists routinely offer terms up to 20 years on larger purchases, with a few extending to 21 years on high-value vessels. Minimum loan amounts for those long terms typically start around $10,000, and some specialists finance into the millions.
Brokers work in this space too, acting as intermediaries who shop your file across a network of lenders. The broker route is most common on luxury yachts, commercial fishing boats, and other transactions where the loan is large enough that a quarter-point rate difference translates into real money over the life of the note.
Online and Direct Lenders
Digital platforms have made boat financing significantly faster. Automated underwriting can produce a decision in minutes, and funds arrive within a few business days of approval. The whole process happens online, with no branch visit.
The catch is that many online lenders offer unsecured personal loans, not secured boat loans. Unsecured loans skip the collateral and the marine survey, which simplifies the process, but the rates are meaningfully higher. Unsecured amounts usually cap at $50,000 to $100,000, which is workable for a smaller boat and unrealistic for anything approaching yacht territory.
Some online lenders do write secured boat loans at rates competitive with banks. When you compare offers, pay close attention to whether the loan is secured or unsecured. That single distinction drives the biggest rate gap you’ll see in boat financing.
Dealership Financing
Arranging financing at the point of sale is convenient, and convenience has a price. The dealer submits your application to one or more banks, or to the manufacturer’s own financing arm, and presents the approved terms. Paperwork, purchase, and funding all happen in one place.
Manufacturers sometimes use their captive finance divisions to promote specific models, especially during boat show season or at the end of a model year. Those promotions can be genuinely competitive. The risk is that dealership-arranged financing may not shop your application as hard as you would, and the convenience can cost you a quarter- or half-point. Getting pre-approved from a bank or credit union before you walk onto the lot gives you a baseline to negotiate against the dealer’s offer.
How to Choose Between Them
The right lender for you comes down to three numbers and the kind of boat you’re buying. Match your situation to the route most likely to approve you at the best rate.
Credit Score
Most boat lenders want a FICO score in the 650 to 680 range, though some specialty lenders work with scores as low as 600. Above 740 you’ll see the best rates and the most flexibility on terms and down payment. Below 650 your options narrow to subprime lenders or unsecured personal loans priced accordingly.
Down Payment
Plan on 10 to 30 percent down. Ten is the most common figure, but lenders push it higher on older boats, larger loans, or thinner credit files. A few lenders advertise zero-down options for well-qualified buyers purchasing new boats, usually paired with higher rates or shorter terms to offset the added risk.
Debt-to-Income Ratio
Lenders divide your total monthly debt payments by gross monthly income. Most want the result under 40 to 45 percent with the proposed boat payment included. If you’re close to that line, paying down a credit card or auto loan before you apply can meaningfully change what you qualify for.
Match the Lender to the Boat
For a new or late-model boat under roughly $100,000 with strong credit, a bank, credit union, or online secured lender will generally give you the best combination of rate and speed. For an older used boat, an unusual hull, or anything above $100,000 or so, a marine lending specialist is worth the extra paperwork because they’ll underwrite the collateral competently. For a smaller boat where you’d rather skip the survey and close fast, an unsecured online loan can work if you can absorb the higher rate. Dealership financing is the right call only after you’ve compared it to an outside pre-approval.
What You’ll Need to Apply
Boat loan applications ask for more documentation than most people expect, especially above $50,000 or so. On the personal side: two years of federal tax returns, recent pay stubs or profit-and-loss statements if you’re self-employed, and a list of your assets and liabilities. The lender uses these to verify income and run the debt-to-income math.
On the vessel side, you’ll provide the Hull Identification Number, year, make, model, and purchase price. For used boats, most lenders require a marine survey performed by a surveyor certified through an organization like the Society of Accredited Marine Surveyors or the National Association of Marine Surveyors. The survey confirms condition and market value, and major findings can affect whether the loan goes through at all. Every lender will also require you to carry hull insurance at full replacement value with the lender named as loss payee, so build the premium into your budget before you commit to a payment.
A Note on the Tax Deduction
If the boat has sleeping, cooking, and toilet facilities, the IRS may treat it as a qualified second home, making the loan interest deductible on your federal return. This matters when you’re choosing a lender, because the loan has to be secured by the vessel to qualify. An unsecured personal loan used to buy a boat doesn’t qualify no matter how well the galley is equipped. The total mortgage debt across your primary home and the boat also can’t exceed $750,000 ($375,000 if married filing separately) for loans taken out after December 15, 2017.3Internal Revenue Service. Publication 936 (2025), Home Mortgage Interest Deduction If the deduction is part of your math, that alone is a reason to steer toward a secured boat loan rather than an unsecured one, even at a slightly tighter approval standard.
