How to Register a Boat: State Title vs. US Coast Guard Documentation Explained
When you purchase a boat, one of the first decisions you’ll face is how to register it. There are two paths available to most boat owners in the United States: registering with your state and receiving a title, or documenting the vessel through the US Coast Guard. Understanding the difference – and knowing which option fits your situation – can save you time, money, and headaches down the road.
The Two Ways to Register a Boat
Both methods are legally valid forms of registration, but they serve different needs and come with different processes, benefits, and ongoing requirements.
| Feature |
State Registration |

| Best for | Smaller boats (under 25 ft) | Larger vessels |
| Tracks ownership history | No | Yes |
| Recognized internationally | No | Yes |
| Numbers on bow required | Yes | No (state may still require registration) |
| Renewal frequency | Varies by state | Every year |
| Sales tax collected by | State | State (if state also requires registration) |
US Coast Guard Documentation: What It Is and When to Use It
Coast Guard documentation is the federal registration system for vessels. For larger boats, it is the recommended approach. Here’s why.
Why Documentation Is Recommended for Larger Boats
- Ownership history tracking: The Coast Guard documentation system tracks ownership history over the entire life of the vessel, making it easy to verify who has owned the boat and when.
- Lien history: It also records lien history, so buyers and lenders can confirm that the title is clear before completing a transaction.
- International recognition: A Coast Guard certificate of documentation is recognized overseas as a valid registration – an important consideration if you plan to cruise internationally.
- Easier resale: When you go to sell, the documentation record gives prospective buyers confidence in the boat’s history and makes it straightforward to demonstrate a clean title.
How to Get Coast Guard Documentation
To document a vessel, you need to complete specific Coast Guard forms and submit them along with supporting paperwork. The required documents typically include:
- The completed Coast Guard documentation forms (CG-1258)
- A copy of your bill of sale
- A copy of the previous owner’s certificate of documentation (if the vessel was previously documented)
Once submitted, it takes a few weeks to receive your certificate of documentation. The certificate looks much like a traditional title.
Should You Hire a Documentation Agency?
If you’d prefer not to handle the process yourself, you can hire a marine documentation agency. For a few hundred dollars, the agency will:
- Conduct a title search on the vessel
- Complete and submit all required forms on your behalf
- Resolve any issues that arise with the Coast Guard during the process
The result is a clean title with minimal effort on your part. For buyers who are unfamiliar with the Coast Guard system or who are purchasing a complex transaction, this can be well worth the cost.
RENEWAL REMINDER: Coast Guard documentation must be renewed every year. Mark your calendar so your documentation doesn’t lapse.
State Registration: What It Is and When to Use It
State registration is typically recommended for smaller boats – generally those under 25 feet. The process and requirements vary by state, but here’s the general framework.
How State Registration Works
To register a boat with your state, you’ll need to submit a bill of sale and a registration application to your state office. The state will collect sales tax at the time of registration and issue registration numbers that must be displayed on the bow of your boat.
State Registration and Documented Vessels
Even if you choose to document your vessel with the Coast Guard, some states will still require you to register the boat at the state level as well. This is how those states collect ongoing sales and excise taxes. Be sure to check your local state regulations as part of your closing process to understand what is required in your jurisdiction.
Special Cases: Dinghies and Trailers
If you purchase a sailboat that comes with a dinghy – and the dinghy comes with a trailer – there are additional registration requirements to be aware of. Both the dinghy and the trailer must be registered separately with your state. The Coast Guard will not document a dinghy or a trailer; that registration is handled exclusively at the state level.
What Paperwork Must Be on Board
No matter which registration method you choose, you are required to keep your registration paperwork on board the vessel at all times. If your boat is boarded by authorities, they will ask to see it.
Coast Guard documented vessels: Keep your certificate of documentation on board.
State-registered vessels: Keep your state title on board.
BOTTOM LINE
For larger boats – especially those used for offshore or international cruising, or those likely to be resold – Coast Guard documentation offers significant advantages in ownership tracking, lien history, and international recognition. For smaller, locally used boats, state registration is typically the simpler and more appropriate choice.

Frequently Asked Questions
What is the difference between state boat registration and Coast Guard documentation?
State registration is handled locally and issues a title with hull numbers displayed on the bow. Coast Guard documentation is a federal system that tracks ownership and lien history over the life of the vessel, is recognized internationally, and is generally recommended for larger boats.
Do I need both state registration and Coast Guard documentation?
Possibly. Some states require you to register a boat at the state level even if it is already documented with the Coast Guard. Check your state’s regulations, as this is how many states collect sales and excise taxes on documented vessels.
What documents do I need to submit for Coast Guard documentation?
You will need to submit the appropriate Coast Guard forms, a copy of your bill of sale, and – if the vessel was previously documented – a copy of the previous owner’s certificate of documentation.
How long does Coast Guard documentation take?
After submitting your forms, it typically takes a few weeks to receive your certificate of documentation.
How often do I need to renew Coast Guard documentation?
Coast Guard documentation must be renewed every year.
Can a documentation agency handle my Coast Guard registration for me?
Yes. Marine documentation agencies specialize in this process. For a few hundred dollars, they will conduct a title search, submit all forms on your behalf, and resolve any issues with the Coast Guard so you receive a clean title.
Do I need to register a dinghy or trailer separately?
Yes. If your boat purchase includes a dinghy and/or a trailer, both must be registered separately with your state. The Coast Guard does not document dinghies or trailers.
What paperwork do I need to keep on board my boat?
If your vessel is Coast Guard documented, keep the certificate of documentation on board. If it is state-registered, keep the state title on board. Either document may be requested if your boat is boarded by authorities.
Is Coast Guard documentation better for selling a boat?
Generally, yes. Because it tracks ownership and lien history over the life of the vessel, it makes it easier to demonstrate a clear title to prospective buyers.
What size boat should be Coast Guard documented vs. state registered?
State registration is typically recommended for smaller boats – under 25 feet, for example. Coast Guard documentation is recommended for larger vessels, especially those used offshore or internationally.
