Online Free USCG Documented Vessel Search

If you have a vessel’s Hull Identification Number (HIN) and/or Official Number, then you can use our site for a free USCG documented vessel search.

This search will provide you with vessel information such as the vessel’s name, its flag, Official Number, and Hull Identification Number. 

Service Information such as the vessel’s status and its Tonnage Information are also included. 

Vessel Documents and Certifications states when the vessel’s most recent Certificate of Documentation was issued as well as its current expiration date. 

Vessel Particulars in the search results consist of the vessel’s length, breadth, depth, the year it was built, and its service/endorsement. 

The search will not include the Managing Owner’s name or address. Past searches may have included that information but in 2018 it was removed from public access. 

To find that information as well as the vessel’s chain of ownership, use this link to file for a Coast Guard Abstract of Title. This Abstract will also include a full account of any liens/encumbrances against the vessel. 

Another way to find the owner of a USCG Documented Vessel: by requesting a Certified Copy of the Certificate of Documentation. This includes the Managing Owner’s name, address, and other information.
