United States. Used boat valuation

Value my boat: what is my boat worth to sell?

Guide values price a model; buyers price a boat. The difference is condition: chiefly the engine, and water where it should not be. This applies a surveyor's and buyer's adjustments to a base value you can defend in negotiation.

Indicative value

A starting point for a negotiation, not a valuation. A surveyor's report and recent comparable SALE prices, not asking prices, are what settle a number.

What actually moves a used boat's value, 2026

Last updated

Guide values price a model and buyers price a boat. This table sets out each adjustment a buyer or surveyor makes, its direction, and the evidence that settles it.

This table describes the adjustments applied in used boat valuation and how each is evidenced. It publishes no percentages or depreciation curves, because values vary by hull type, engine, region and season and no public source sets a general rule; the calculator's inputs exist to be replaced with figures from your own comparables and survey. Documentation and survey references point at US Coast Guard recreational boating material and at two marine surveyors' associations as starting points for verification rather than as endorsements. Nothing here is a valuation or survey.

What actually moves a used boat's value, 2026

Engine hours and service historyDown with hours, up with recordsRepower is often a large share of hull valueLogbook, service invoices, compression and oil analysis
Moisture in the structureDown, sometimes decisivelyWet coring is expensive and hard to priceMoisture readings in a survey report
Survey findingsDown by cost to rectifyBuyers deduct the fix, not the inconvenienceA written survey with itemised recommendations

Trailer, electronics and gearUp, but less than they costBuyers discount second-hand electronics heavilyItemised inventory with ages
Region and seasonBoth waysA boat is worth more where the season is startingComparable sale prices in the same market
Title, liens and documentationCan stop a saleA defect is not a price issue, it is a completion issueDocumentation records and a lien search
  • Guide values price a model, so on any boat more than a few seasons old the survey moves the number more than the model year does.
  • Engine hours are the largest single adjustment on most powerboats, because a repower can be a substantial share of hull value.
  • Buyers deduct the cost to rectify survey findings, so a seller who has already fixed them negotiates from a stronger position than one offering a discount.
  • Asking prices and achieved prices diverge widely on boats, which is why comparables should be sales rather than listings.
  • Title, lien and documentation defects stop sales rather than adjust prices, and are checkable before a price is agreed.

The longer answers, with sources.

Behind the numbers

  • Every percentage above is an input for you to replace. We publish no depreciation curve or standard adjustment, because used boat values vary by hull, engine, region and season and no public source sets a general rule.
  • The base value should be a comparable SALE price where you can find one. Asking prices are a wish list, and on boats the gap between asking and achieved is frequently wide.
  • Engine hours are entered against what you consider normal for the age rather than against an absolute, because normal differs enormously between a freshwater weekend boat and a coastal charter.
  • Survey findings are entered at the cost to rectify. That is the number a buyer will deduct, and a seller who has already fixed them has a stronger position than one offering a discount.
  • Not modelled: outstanding finance, liens, unpaid dockage and any title or documentation defect. Each of those can stop a sale entirely rather than adjust its price.

Boat Value Calculator is an information site. It is not affiliated with, endorsed by or connected to any agency, association or company named here. Nothing on it is valuation, survey, insurance, legal or tax advice. We take no commission and carry no paid placements. This tool produces an indication from a base value you supply and adjustments you choose. It is not a valuation and not a survey, and no depreciation curve or standard adjustment is published here because used boat values vary by hull, engine, region and season. Only a qualified marine surveyor can assess a specific vessel, and title, lien and documentation questions are for the relevant registry and your own adviser.

Questions, answered directly

How much is my boat worth?

What a buyer in your region will pay this season, which is rarely the guide figure. Start from a guide value or a comparable sale, then adjust for engine hours, condition, survey findings and the gear that goes with the boat. The calculator above does that arithmetic so you can see each adjustment on its own line.

How do I find the fair market value of my boat?

Fair market value is the price a willing buyer and a willing seller agree with the facts known to both. The closest evidence is the sold price of similar boats in your region and season. Asking prices are a ceiling, and a survey settles the condition questions a buyer will otherwise discount for.

How much should I sell my boat for?

Price it at your adjusted value with room for the negotiation you expect. Fix survey findings before listing where you can, because a buyer deducts the cost of a fix plus a margin for arranging it. A boat priced above its comparables tends to sit, and a long listing becomes a reason to offer less.

Is there a free boat value lookup or boat price checker?

Published guide values are the lookup most people mean, and they price a model, year and configuration. Use one as the base value in the calculator above, then let the adjustments for hours, condition and survey move it, because the guide cannot see your boat.

What is my boat's trade-in value?

Lower than its private sale value, because a dealer prices in reselling it, any preparation and time on the lot. No dealer we read publishes a trade-in schedule. Get the trade-in offer in writing and compare it with your private-sale figure from the calculator, less the time and cost of selling it yourself.

How accurate is a boat value calculator?

A starting point, not a valuation. Guide values price a model, year and configuration, and cannot see engine hours, moisture in the structure or the electronics. On a boat more than a few seasons old the survey moves the number more than the model year does. So the calculator starts from a base and applies a buyer's and surveyor's adjustments.

Should I use asking prices as comparables?

Only as a ceiling. Boats sit on the market and asking prices drift upward from reality, so the gap between asking and achieved is frequently wide. Weight actual sale prices for comparable boats in the same region and season heavily instead. A listed comparable tells you what somebody hopes for; a sold one, what somebody paid.

How much do engine hours affect value?

On most powerboats it is the largest adjustment, because a buyer eventually prices a hull plus a repower. What matters is hours against expected use. Two hundred hours on a twenty year old boat suggests long idle periods, its own problem; eight hundred on a well serviced coastal boat can be unremarkable. Records move buyers more than the meter.

Is it better to fix survey findings or discount for them?

Rectifying usually recovers more, because a buyer deducts the cost of the fix plus a margin for arranging it themselves. The exception is a finding large enough that the boat should be sold as a project. Then pricing it honestly attracts the buyer who wants that, rather than wasting both parties' time.

What can stop a boat sale entirely?

Title and documentation defects, liens or outstanding finance, and unpaid yard or dockage bills. These are completion issues, not price issues. A federally documented vessel has a federal record; state titled boats have state records. A lien search before a deposit is a small cost against a large exposure: check them before a price is agreed.

Should I get a survey before or after agreeing a price?

Before, where you can. A price agreed subject to survey invites a renegotiation neither side enjoys, because the seller has already emotionally banked the first figure and treats every finding as an attack. Where a seller offers a recent survey, note who commissioned it and when; it is useful information rather than a substitute for your own.

Does freshwater use really matter?

Yes, and consistently. Corrosion history sits behind almost every engine and fitting question, so a freshwater boat of the same age and hours is genuinely worth more. Berthing history is checkable and worth documenting when selling, because a buyer who cannot verify it will assume the less favourable case and price accordingly.
