BOAT IDENTITY LOOKUP

Search by HIN

Enter the 12-character identifier from the starboard transom. We’ll find the boat or make its HINBook profile available—without importing owner information.

PRIVATE LOOKUP RECORD When you submit an exact HIN, HINBook records the HIN, time, signed-in account if any, IP address, and basic browser/device details for security and lawful investigation support. These details are never public; account, network, and device attribution expires after 90 days unless a documented legal hold applies. Privacy details →

01 / DECODE

Read the build code

Modern HINs identify the manufacturer code, serial, certification month and year, and model year. Supported 1972–1984 formats are preserved and routed for manual review.

02 / MATCH

Check public sources

Hinbook can associate manufacturer, documented-vessel, and recall records using narrowly selected non-owner fields. A source label shows where each fact came from.

03 / CLAIM

Claim the HIN profile

Create your connection to the profile now. Ownership remains unverified until a HINBook moderator approves the claim after review; supporting evidence may be requested.

Privacy boundary: Hinbook never publishes a full HIN. Only the signed-in profile creator or an approved owner can see it.
