Boat History Report by HIN
Buyers ask for a “boat history report” to check a used boat by its Hull Identification Number. CarWhere decodes any HIN free — builder, build date, model year, serial — then the $9.99report adds the builder's identity and business status (USCG MIC database) and a CPSC marine-recall check, every section sourced and dated. It is not a title or stolen-vessel report — we show you how to run those checks yourself below. No subscription; emailed link, 90-day access.

What each source can — and cannot — show
| Source category | What it can show | What it cannot prove |
|---|---|---|
| USCG MIC database (in report) | The builder behind the first 3 HIN characters, location, and business status | Current title or liens |
| HIN format rules / 33 CFR 181 (in report) | Whether the HIN is well-formed; build date and model year | Ownership history |
| CPSC marine recalls (in report) | Recalls published for the builder — boats, engines, marine gear | Whether your exact hull was already repaired |
| Title, theft & accidents (check yourself) | Your state titling agency, an NICB/BoatUS stolen-boat search, and a marine survey | Not included in this report — verify these directly |
What this report does not include
- It does not prove legal ownership and does not guarantee no lien exists — liens and titles are state records, checked through your state titling agency.
- It does not replace a professional marine survey for condition.
- It may not include private insurance, marina, or state records unavailable to public and commercial datasets.
- Every section is labeled with its source and last-checked date; sections with no records say so plainly.
Sources: HIN requirements per 33 CFR 181 subpart C (12 characters; first three = manufacturer code; one HIN per hull); manufacturer identities from the USCG MIC database; the NICB advises matching the HIN against title and registration paperwork on any used-boat purchase.

FAQ
What does the CarWhere boat report include?
Two sections keyed to the HIN, each labeled with its data source and last-checked date: full hull identification with the builder identity, location, and business status from the USCG MIC database, and a recall & safety-notice check against the CPSC marine-recall database. It is built entirely from free public records. It is not a title, ownership, accident, or stolen-vessel report — those checks are described below so you can run them yourself.
Is a boat history report the same as a title search?
No. Titles and liens are state-level records checked through your state titling agency. A history report is informational research that complements — never replaces — a state title check and a professional marine survey.
Why is the report keyed to the HIN?
The HIN is the only identifier that follows a boat through its whole life — across owners, states, and registration numbers. Registration numbers change; the HIN never does.
How much does it cost?
$9.99 one-time — no subscription, ever. The HIN decode itself is free with no account. Commercial boat-history services charge $25+ per report.
Is a boat HIN the same as a VIN?
No. Cars use a 17-character VIN; boats use a 12-character HIN (Hull Identification Number) under 33 CFR 181. Buyers often say "boat VIN," but the correct identifier is the HIN. CarWhere decodes the HIN free and keys the full report to it.
Does a HIN show the boat owner, liens, or accident history?
No. A HIN decode shows factory identity only — builder, build date, model year, and serial. Ownership and liens are state title records, and theft/accident records live in separate databases. The $9.99 report adds the builder’s business status and a CPSC marine-recall check, but it does not check title, theft, or accidents — verify those with your state titling agency and the steps below.
How do I check if a boat is stolen before buying?
Confirm the HIN on the hull (starboard transom corner) exactly matches the HIN on the title, registration, and insurance card; look for grinding, mismatched fonts, or a re-bedded plate; verify the title with your state titling agency; and ask the state boating agency and local law enforcement whether the HIN or registration is reported stolen (commercial boat-history databases may add records, though coverage is incomplete). Note NICB’s VINCheck is for vehicle VINs, not boat HINs. CarWhere’s free decoder confirms the builder, build date, and model year so you can match the paperwork — the theft, title, and physical checks are yours to run. The NICB advises matching the HIN to paperwork on every used-boat purchase.
Where is the HIN on a boat?
On the outside upper starboard (right) corner of the transom, within two inches of the top. Since 1984 a duplicate HIN is also molded into an unexposed interior location as an anti-theft measure. On a pontoon boat, check the upper starboard corner of the transom crossbar or the aft starboard crossmember. All locations — and the title and registration — should match exactly.
