Research the Type of Boat You Want
Before purchasing from a private seller, determine which boat type suits your intended use. Making the right choice upfront prevents costly mistakes and ensures your investment matches your boating lifestyle.
Steps to Identify Your Ideal Boat
- Define your primary use – Determine whether you’ll primarily fish, cruise, sail, or participate in water sports, as this dictates boat design requirements.
- Consider boat categories – Sailboats harness wind power and offer a more traditional boating experience, while motorboats rely on engines for propulsion and excel at activities like water sports and fishing.
- Evaluate size requirements – Runabouts typically run 15-30 feet with outboard power and work well for fishing, cruising, and watersports. Larger vessels offer more amenities but require more storage space and higher operating costs.
- Match hull type to conditions – The boat’s ultimate use decides how its hull is designed and shaped. Deep-vee hulls handle rough offshore conditions, while flat-bottomed boats excel in calm, shallow waters.
- Research specific models – Read reviews, join online forums specific to your boat type, and talk to current owners about maintenance requirements and performance characteristics.
Consider trailering and storage – Verify your tow vehicle can handle the boat’s weight and that you have adequate storage space at home or access to affordable marina facilities.
Set a Budget
The purchase price represents only part of your total investment. Understanding complete ownership costs prevents financial surprises and ensures sustainable boat ownership.
Budget Components to Consider
Factor in additional costs like insurance, maintenance, and docking fees when calculating affordability. Insurance costs vary based on boat value, your experience level, and operating location, ranging from several hundred to several thousand dollars annually.
Registration fees are mandatory and vary by state, with some charging based on length and others on value. Most lenders require a professional marine survey to assess the boat’s condition and value, typically costing $15-25 per foot.
Annual maintenance expenses should represent 10-15% of the boat’s value. Marine engines need regular service, winterization in cold climates, and periodic repairs. Electronics fail, upholstery wears, and gel coat requires attention over time.
Storage costs add up quickly. Marina slips range from $50 to $500+ monthly, depending on location and amenities. Even home storage may require property improvements or off-site facilities.
Additional expenses include fuel, cleaning supplies, safety equipment replacement, and unexpected repairs. Set aside an emergency fund equal to at least 10% of the purchase price for unforeseen issues that arise after purchase.

Dedicated boating marketplaces typically attract serious sellers and provide better fraud protection than general platforms.
Check Boat History
Verifying a boat’s history prevents purchasing vessels with hidden problems, outstanding liens, or fraudulent documentation. This research step protects your investment and legal ownership rights.
Documentation Verification
The Hull Identification Number should be verified to ensure it matches all paperwork. This 12-character HIN appears stamped on the transom and must match the title, registration, and any Coast Guard documentation. Discrepancies indicate potential title washing, theft, or reconstruction issues.
In the United States, check that there are no liens on the title that you might become liable for as the new owner. Outstanding liens mean another party holds financial claims on the vessel. The US Coast Guard maintains documentation records for larger vessels, while state DMV offices verify title status for smaller boats.
Maintenance and Damage Records
Request maintenance logs showing regular service history. Organized records indicating routine oil changes, winterization, and repairs suggest responsible ownership. Absence of documentation may indicate neglect or concealed issues.
Previous damages and maintenance history should be verified through available documentation. Insurance claims, repair receipts, and service records reveal the boat’s true condition. Some vessels have experienced hurricanes, collisions, or major mechanical failures that have received cosmetic repairs while underlying problems persist.
Boat history reports can uncover accidents and insurance claims. Request copies of all service records, warranty documents, and previous survey reports. Contact the manufacturer using the HIN to verify build date and original specifications.
Inspect the Boat
Thorough physical inspection identifies existing problems and potential issues before purchase. The inspection complexity varies with boat type and size, requiring systematic examination of all major systems.
Inspection Checklist
Hull and Structure:
- Check for cracks, soft spots, or blistering gel coat
- Tap hull and deck to identify delamination or rot (solid sounds are normal, hollow thuds indicate problems)
- Examine for impact damage or previous repairs
- Inspect through-hull fittings for corrosion
- Check transom condition and mounting points
Engine and Mechanical:
- The engine should start easily and sound smooth
- Look for oil leaks, corrosion, and frayed wiring
- Check fluid levels and colors (milky oil indicates water intrusion)
- Examine belts, hoses, and clamps for wear
- Test steering system operation
- Verify trim functions properly
Electronics and Electrical:
- Test that the lights, electronics, instruments, and audio system are working
- Power up GPS, fish finders, and radios
- Check navigation lights and horn operation
- Inspect wiring for corrosion or damage
- Test bilge pump operation
Safety Equipment:
- Verify fire extinguishers are current and charged
- Check life jackets for proper condition and Coast Guard approval
- Inspect flares for expiration dates
- Confirm pumps for live wells and bait wells function
For bigger, more expensive boats, hiring a professional marine surveyor for a few hundred dollars provides a condition and valuation survey.

Perform a Water Test
Water testing reveals operational issues impossible to detect at the dock. This critical step verifies that all systems function properly under actual operating conditions.
You’ll want to sea trial any boat, and the ride should be long enough to warm up the engine and verify all systems function properly. A proper water test exceeds a brief run around the dock—the engine must reach full operating temperature while you evaluate handling at various speeds.
Listen for unusual noises, vibrations, or performance irregularities. Test acceleration, turning radius, and stopping ability. Verify the engine maintains consistent RPMs without hesitation or smoking. Check that the boat tracks straight without pulling to either side.
All systems need verification during the test, including engine performance, trim function, lights, electronics, instruments, audio system, and pump operation. Run bilge pumps, test live well circulation, and operate all installed equipment. Monitor engine temperature gauges and oil pressure throughout the test.
For smaller boats, meet at the launch ramp to inspect both the vessel and trailer during the water test. Evaluate how the boat loads and unloads, and verify the trailer’s condition under actual use.
Handle Paperwork
Proper documentation ensures legal ownership transfer and protects both parties during the transaction. Missing or incorrect paperwork creates legal complications and potential financial liability.
Paperwork Checklist
Bill of Sale Requirements:
- A bill of sale must include the boat’s year, make, model, Hull Identification Number, purchase price, date of sale, and both parties’ signatures
- Double-check that the HIN is correct, along with the length, year, make, and model
- Confirm the bill of sale details, all included amenities, and their serial numbers if applicable
- Bring identification and necessary documents to a notary to finalize the sale
Title Transfer:
- Check that there are no liens on the title that you might become liable for
- If the seller has a lien, one approach involves going with the seller to their bank to pay off the lien and receive the title at that time
- Verify the title is in the seller’s name
- Confirm that the HIN on the title matches the boat
Registration and Documentation:
- State registration or US Coast Guard documentation must be transferred into your name after purchase
- Complete the Exchange, Reinstatement, or Return to Documentation application for Coast Guard documentation through the National Vessel Documentation Center
- Confirm state registration display requirements before operating the boat
- Submit required forms to your state’s DMV or marine registration office within the specified timeframe

FAQs – How to Buy a Boat from a Private Seller
How do you buy a boat from a private seller?
Start by researching boat types that match your intended use, then set a comprehensive budget including insurance, maintenance, and storage costs. Find boats on platforms like Boat Trader or Craigslist, verify the Hull Identification Number and check for liens, conduct thorough inspections of hull, engine, and electronics, perform a water test, and complete proper paperwork, including a bill of sale and title transfer through a notary.
What paperwork do I need to buy a boat?
You need a bill of sale including the boat’s year, make, model, Hull Identification Number, purchase price, and signatures from both parties. Obtain the boat’s title with no liens, verify it matches the seller’s name, and complete state registration or US Coast Guard documentation transfer. Bring identification to a notary to finalize the transaction, and submit registration forms to your state’s DMV or marine office.
How to protect yourself when buying a used boat?
Verify the Hull Identification Number matches all documentation and check for liens on the title through the US Coast Guard or state DMV. Request maintenance logs and service records, hire a professional marine surveyor for boats over $10,000, conduct a comprehensive water test to check all systems, and use secure payment methods like certified checks or escrow services for high-value purchases.
Do I have to pay VAT on a second-hand boat?
In the United States, boats don’t have VAT (Value Added Tax). Instead, you may owe sales tax based on your state’s regulations when purchasing a used boat from a private seller. Sales tax rates and requirements vary significantly by state, with some states exempting boats or charging based on purchase price. Check your state’s DMV or marine registration office for specific sales tax obligations before completing your purchase.
