Boat Registration & Titling vs USCG Documentation
Coast Guard Documentation vs State Registration
We’ve covered the complex rules of state titling and documentation before, but this article aims to simplify it for beginners. This guide applies only to the United States. If you’re in Canada, note that the terminology and systems are completely different.
Boat Documentation vs Titling: What’s the Difference?
When you buy a boat in the U.S., you’ll come across two main systems of ownership identification:
- State registration and titling, and
- Federal documentation (through the U.S. Coast Guard).
While both serve to identify your vessel and prove ownership, they operate under different authorities and have distinct purposes.
What Is U.S. Coast Guard Documentation?
Documentation is a national form of vessel registration managed by the National Vessel Documentation Center (NVDC), part of the U.S. Coast Guard.
It’s primarily used for:
- Commercial vessels engaged in fishing, transport, or trade in U.S. waters.
- Recreational vessels over five net tons (typically about 25 feet in length or longer) that qualify for federal documentation.
A Certificate of Documentation (COD) serves as both proof of ownership and nationality of the vessel.
It’s recognized internationally, which makes it valuable for boats that travel across state or national waters.
Benefits of Documentation
- Recognized as an official proof of ownership nationwide.
- Facilitates financing—lenders often prefer documented vessels.
- Simplifies international travel and customs clearance.
- Provides a recorded chain of ownership with the NVDC.
What Is State Registration?
Boat registration is handled at the state level, usually through your state’s Department of Motor Vehicles (DMV) or Department of Natural Resources (DNR).
Almost every state requires registration for motorized vessels and sometimes even for sailboats or larger personal watercraft.
When you register your boat with the state:
- You receive a state registration number (displayed on the hull).
- You may also receive a title, which proves legal ownership—similar to a car title.
- You pay annual or biennial fees, depending on the state.
Note:
Some states issue both a title and registration, while others only register the vessel.
Boat State Title vs USCG Documentation
| Feature | State Title / Registration | USCG Documentation |
|---|---|---|
| Authority | State Government (e.g., DMV or DNR) | Federal Government (U.S. Coast Guard / NVDC) |
| Proof of Ownership | State-issued Title | Certificate of Documentation |
| Identification | State registration number displayed on hull | Official vessel name and hailing port displayed on stern |
| Vessel Size Eligibility | Any size (varies by state) | 5 net tons or more |
| Renewal | Every 1–2 years (varies by state) | Annually with the NVDC |
| Primary Use | Local/state waters | Interstate or international waters |
| Financing | State title can be used as collateral | Preferred by marine lenders |
| Public Record Search | State-level databases | NVDC vessel documentation database |
What’s the Difference in a Nutshell?
- State registration = Your local “license plate” for your boat.
- USCG documentation = Your federal “passport” that identifies the vessel nationally and internationally.
In short, registration is managed by your state, while documentation is managed by the federal government (military — coast guard).
Why You Might Need Both
In some states, even if your vessel is federally documented, you may still be required to register it with the state—especially if it’s kept or operated primarily in that state’s waters.
Having both ensures:
- Compliance with local and federal laws, and
- A more complete ownership history for verification.
This combined record is also invaluable for boat history reports—for example, through Boat-Alert.com, which aggregates data from both state and federal sources to uncover liens, accidents, or theft history.
Boat Registration Lookup
If you want to research a vessel’s background, you can use:
- State boat registration databases, or
- The USCG NVDC database, which lists all documented vessels.
- Boat-Alert.com or boat-abstract.com
Contact the NVDC
The National Vessel Documentation Center (NVDC) is responsible for processing vessel documentation applications and maintaining federal ownership records.
Contact the NVDC – what is the NVDC
You can contact them for:
- Applying for documentation,
- Renewing your certificate, or
- Requesting an Abstract of Title, which shows the ownership and lien history of a documented vessel.

In Summary
| Topic | State Registration | USCG Documentation |
|---|---|---|
| Level | State | Federal |
| Document Issued | Registration & possibly Title | Certificate of Documentation |
| Marks on Boat | Numbers on both sides of bow | Name & hailing port on stern |
| Common for | Smaller boats | Larger or financed vessels |
| Database Lookup | State DMV/DNR | NVDC |
Both are essential in their own ways—state registration keeps you legal locally, and federal documentation gives your boat national recognition.
When buying or selling a boat, make sure both records are clean and up to date. That’s how you protect yourself from future ownership disputes or hidden liens.
