Is there a Kelley Blue Book for used boats?

No, Kelley Blue Book does not publish values for used boats. KBB's own site explicitly states it covers cars, motorcycles, and a handful of other vehicle types, but not boats, outboard motors, or trailers.

Boats are priced by different resources built specifically for the marine market, since boat value depends heavily on hull condition, engine hours, electronics, and local demand rather than a standardized model-year formula. Guides commonly used in the marine industry include the NADA Marine Appraisal Guide and the ABOS Marine Blue Book, along with sold-boat data tracked by brokers and dealers. These tools can offer a rough starting range, but they typically price the boat, motor, and trailer as separate components and rely on generalized condition categories rather than an inspection of your specific vessel.

For anything beyond a ballpark figure, such as insurance coverage, estate settlement, a charitable donation deduction, divorce proceedings, or loan collateral, a published guide value usually isn't defensible enough on its own. Those situations call for a professional boat appraisal that documents the vessel's actual condition, equipment, and market comparables, and is prepared in accordance with USPAP.

Guide value vs. a formal appraisal

• Guide/calculator value: A quick estimate based on make, model, and year, useful for a general sense of price range.
• Formal appraisal: A signed report from a credentialed marine appraiser that verifies condition, documents comparable sales, and states a supportable fair market value for a specific intended use.

If you've already checked a boat value guide and need a number that will hold up with an insurer, the IRS, or a court, our appraisers can prepare a fixed-fee, USPAP-compliant report after reviewing your vessel's details. It's also worth reading about the NADA guide for boats if you're comparing available resources before deciding whether a formal appraisal is necessary.
