What a HIN lookup shows
A boat's HIN is its 12-character fingerprint, like a car's VIN. We search the U.S. Coast Guard's federal vessel registry (PSIX) for documented boats and yachts — returning the builder, model year, hull material, dimensions, service type and current documentation status. As with vehicles, we never show owner personal information.
Before you buy a used boat
Confirm the HIN on the transom matches the paperwork, check the documentation status, and run it here before you pay. A few minutes of checking can save you from a costly mistake on the water.

Frequently asked questions
Where is the HIN on a boat?
It's usually stamped on the upper starboard (right) side of the transom, and may also be on documentation and the registration.
Is the boat lookup free?
Yes — U.S. Coast Guard documented-vessel records are free to search.
Does it show the boat's owner?
No. The Coast Guard removed owner personal information from public records; we show vessel details only.
