Before buying a documented vessel—or even just out of curiosity—it’s normal to want to know more about its history. Has it been properly documented? What is its official service designation? When does the Certificate of Documentation expire? These are all questions you can answer quickly and easily with the right tools. If you’ve ever wondered how to check boat history for free, our portal is designed to give you instant access to key federal data.

Here at the National Documentation Portal, we make it simple for anyone to search Coast Guard vessel records at no cost, offering a clear starting point for understanding a boat’s federal documentation background.

With just a few details about the vessel, you can view its documentation status and many of its most important recorded specifications.

How to Check Boat History for Free Through Our Portal

We make it possible for users to search the Coast Guard’s vessel documentation database free of charge. All you need is the vessel’s Official Number or Hull Identification Number (HIN). These unique identifiers allow the federal system to locate and display that vessel’s publicly available documentation file.

To begin, visit our site’s vessel search section. Once you input the relevant number, our system connects directly to the U.S. Coast Guard database and returns real-time information about the vessel’s documented status. This function is available to everyone and doesn’t require account creation, subscription, or payment.

We’ve designed our lookup tool to be fast, easy to navigate, and accurate. It gives prospective buyers, current owners, brokers, or marine professionals the ability to verify vessel information in just a few moments.

Information You Can Expect From the Lookup

The free search provided through our portal pulls up federally documented details related to the vessel. This includes:

Vessel Name
Official Number
Hull Identification Number
Current documentation status (active, expired, or deleted)
Date of issuance and expiration of the most recent Certificate of Documentation
Vessel’s service designation (e.g., recreational, coastwise, fishery, registry)
Dimensions (length, breadth, depth, and gross/net tonnage)
Hailing port
Type of propulsion and hull material

This search provides reliable data directly from the U.S. Coast Guard’s records, helping users assess whether a vessel is actively documented and how it has been categorized. It is especially useful for confirming that the vessel is eligible for a certain type of operation or to verify that the current Certificate of Documentation is valid.

It’s important to note that the federal government makes certain vessel information publicly accessible, but personal or financial records are not included. That means ownership history and encumbrances are excluded from this search and must be requested separately.

What the Free Search Won’t Show You: When to Request an Abstract of Title

While our free lookup service provides plenty of valuable information, it does have limitations. It will not include:

A complete ownership chain
Whether there are any recorded liens or mortgages
The existence of claims or encumbrances against the vessel

To obtain this deeper level of vessel history, you’ll need to request an Abstract of Title, a service we also provide. This document is a comprehensive Coast Guard report that details the chronological record of all official actions taken on the vessel. That includes ownership transfers, changes in documentation status, recorded liens or satisfactions, and more.

If you are considering purchasing a documented vessel, this is the best way to determine whether the current owner has the legal right to sell the vessel and whether any outstanding financial claims are associated with it.

Our site makes it easy to apply for an Abstract of Title, offering the same guided process and secure submission system used throughout our platform. You can submit the request digitally, and once processed by the Coast Guard, the abstract will be delivered to you in a timely manner.

How Checking a Boat’s History Helps Owners and Buyers Alike

Verifying a vessel’s history is useful in many scenarios, not just during a purchase. Current owners may use it to check their documentation status, including expiration dates and active endorsements. Lenders and insurers may use the lookup to ensure the vessel meets their criteria before extending coverage or financing.

Having access to real-time, federally recorded vessel data offers peace of mind and legal clarity. If a vessel is found to be undocumented or inactive, the buyer can take steps to obtain the proper documentation—or use that status to renegotiate terms. If a vessel appears active and compliant, the buyer can gain real confidence in moving forward.

By offering free access to this information, our portal removes barriers for those who want to make informed decisions and stay in line with federal standards.

Next Steps Using Our Portal’s Services

Once you’ve performed a boat history search, you may want to take additional action depending on what the results show. If you discover that the vessel is active and properly documented, and you plan to move forward with a transaction, you can use our platform to:

Transfer ownership
Renew documentation
Request an Abstract of Title for further investigation
Apply for a change of name or hailing port if you become the new owner
Replace a lost or damaged Certificate of Documentation
Reinstate expired documentation

Each of these functions is available directly through our secure online portal. We help ensure that every step is clear, compliant, and guided by the most up-to-date Coast Guard procedures.

Our goal is to make the documentation process easier—not just for boat owners, but for anyone interacting with federally documented vessels. With our tools, you can manage nearly every aspect of vessel documentation from your computer, eliminating paper forms, mailing delays, and unnecessary guesswork.
