Can I deduct boat loan interest?

If the boat qualifies as a second home (has sleeping, cooking, and toilet facilities), loan interest may be deductible under current US tax rules. Check with a tax professional.

Why are boat loan APRs higher than auto loan APRs?

Boats depreciate faster and are harder to repossess and resell. Lenders price that risk into the rate.

What credit score do I need for a boat loan?

Most marine lenders require 680+ FICO for competitive rates; 700+ for prime rates. Below 680, expect APRs 3-5 points higher than the prime rate. New-boat loans often require lower credit thresholds (650+) than used-boat loans because lenders prefer the predictable depreciation curve and warranty coverage. Specialty lenders (Trident Funding, BoatUS, Essex Credit) sometimes work with mid-tier credit at 4-7% rate premiums.

What's the typical down payment on a boat?

10-20% on new boats, 15-25% on used. Marine lenders often require larger down payments than auto loans because of higher depreciation risk. On a $40K boat, 20% down ($8K) is the typical marine-loan target. Some lenders offer 10% down on premium new boats with strong credit, but those loans usually carry higher APRs. The gap between 10% and 20% down on a $40K boat at 8.5% APR over 10 years: about $5K in total interest.

What other costs should I budget for boat ownership?

Annual ownership costs typically run 10-15% of the boat's value. On a $40K boat: $4K-6K/year. Breakdown: dockage ($2K-12K depending on location, slip type), insurance ($300-1500/year), winter storage and shrink-wrap ($500-1500), maintenance ($500-2000), fuel (varies wildly with usage), USCG-mandated equipment (life jackets, flares, fire extinguishers — $200-500). Plus haul-out and bottom paint every 1-3 years ($800-2000). Boats are 'BOAT' = 'Bring Out Another Thousand'; budget conservatively.

Should I finance a used boat or pay cash?

Cash is cheaper if you have the savings without depleting emergency funds (3-6 months expenses untouched). Financing makes sense if: cash would deplete reserves, the boat is a luxury you'd otherwise skip, or you can earn higher returns investing the cash than the loan APR (currently rare given 8-10% boat APRs vs. 7% expected stock returns). For most retail buyers, financing 70-80% of the purchase price preserves cash flow and emergency fund flexibility.

What it does

A free boat loan calculator built around the realities of marine financing: longer terms (10-20 years is common), higher APRs than auto loans, and a much steeper depreciation curve. Enter loan amount, APR, and term — get monthly payment and total interest before you sign anything at the marina.

Boats depreciate faster than most people expect. A loan that outlives the boat’s useful life is a real risk, which is why shorter terms are friendlier even though the monthly is higher. Budget for dockage, fuel, insurance, and winter storage before you commit to the payment.
