Where are Maryland Boats Registered?

Remember, some states have titling for boats and others do not. Maryland issues both registrations and titles for all non-exempt boats operating within its jurisdiction. These are administered by the MD STATE Department of Natural Resources (DNR ). Outboard motors are not titled or registered in Maryland. Boat trailers are registered and titled.

Does Maryland have clean titles? Boat titles are always “clean” unless a state has enacted UCOTVA. All other states will not have any indication on the title that the boat has a salvage or total loss brand like cars have on their titles.

Did you know that 200,000 boats registered in the State of Maryland make up 2% of all USA vessel registrations?

Maryland Boat Registration Numbers

Maryland boat registration numbers begin with a “MD”. The MD designation is followed by four numbers and then two letters like in most states. You will have to display these as shown above, if your boat is not documented at the USCG. Put the MD boat registration sticker tab next to it. The state reg. number should not be confused with the 12 character Hull ID (HIN).

All boats manufactured after 1972 are required to have a 12 digit hull identification number affixed to the vessel by the manufacturer. State assigned hull numbers prefixed with the letters “MDZ” are available for home made boats and those without factory designations. Hull number inspections are not required in Maryland unless there is a discrepancy. (use to validate your HIN formatting is good)

Exceptionally, a Coast Guard documented vessel does not need to display the state registration number but instead they would display the state registration tabs, an owner designated vessel name, and a hailing port. The USCG Official documentation number must also be affixed on other locations on the boat: interior location in the hull itself or an integral part of the hull.

Boat Liens Database In Maryland

Security interests in state titled boats are recorded with the Department of Natural Resources (DNR ) in MD. These will be shown on both the registration and title certificates if there are any. Security interests in boats that are neither titled or USCG documented are recorded with the Secretary of State as Uniform Commercial Code (UCC) filings. If the vessel is USCG documented, a lender’s security interests will be recorded with the National Vessel Documentation Center (NVDC) and are indexed on the boat’s abstract of title. This is different from state registration lookups and can be ordered at

Tax liens may be flagged on boat registration records, recorded as UCC filings, shown on state revenue records, or filed with a county clerk’s office. There are no provisions for recording mechanic’s liens or other non-secured claims against state titled boats. Uniform Commercial Code searches are available online from the Secretary of State.

Boat title and registration records in Maryland are maintained by the Department of Natural Resources (DNR ). This agency does not facilitate online searches on their website but you can search the database.
