F.A.Q.

How Do I Mark My Vessel?

Marking your vessel is an essential step in its documentation and legal recognition under United States Coast Guard (USCG) regulations. Whether you’re a first-time vessel owner or looking to update your vessel markings, understanding the proper procedures is crucial to ensuring compliance with maritime laws.
Vessel Official Number Marking Requirements
Every documented vessel is assigned a unique official number by the USCG. This number is paramount in identifying the vessel and must be marked in a specific manner to ensure durability and visibility.
Placement and Format of the Official Number
The official number must:

Be preceded by the abbreviation “NO.” to clearly indicate its designation as the vessel’s registered official number.
Consist of block-type Arabic numerals that are clearly legible and at least three inches in height.
Be marked on a clearly visible, interior structural part of the hull where it won’t be exposed to external elements, such as the weather or water, to maintain its longevity.

Permanence of the Official Number
The number must be affixed permanently in a way that prevents alteration, removal, or replacement without causing obvious damage or scarring to the surrounding hull area. Using methods such as engraving, carving, or etching ensures the number meets this requirement while maintaining compliance with USCG standards.

Why it’s important: Permanent marking discourages tampering and ensures a reliable identification method in case of disputes, sales, or inspections.
Vessel Name and Hailing Port Marking Requirements
Beyond the official number, all documented vessels must display their name and hailing port, which serve as the vessel’s primary external identifiers.
Vessel Name Markings
The vessel name must comply with specific regulations to ensure clarity and distinctiveness:

Must be composed of letters from the Latin alphabet, Arabic numerals, or Roman numerals.
Cannot exceed 33 characters in length.
Must not replicate distress signals or incorporate obscene, indecent, or profane language or racial/ethnic epithets.

For recreational vessels, the name should be displayed on some clearly visible exterior part of the hull. On commercial vessels, additional requirements apply:

Vessel names must also appear on both the port and starboard bow.
Name markings must be at least four inches high and comprise clearly legible lettering to ensure visibility from a distance.

Hailing Port Requirements
The hailing port can denote the vessel's “home base,” but it doesn’t have to. You can pick any location anywhere in the United States, even one that doesn’t have a port. That said, it must meet the following specifications:

The name of the hailing port must include a location, specifying a U.S. state, territory, or possession. Abbreviations for the state or territory name are accepted.
Must be displayed alongside the vessel name on the exterior parts of the hull, such as the stern. Letters and numerals used for marking must also stand a minimum of four inches in height and must be placed in visible locations.

For example, a vessel based in Los Angeles could display its hailing port as “Los Angeles, CA.” However, it doesn’t have to be. You could mark it “Silver Lake, CA,” or any other location in the United States. It doesn’t even have to be a location with a port.
Marking Permanence
You have flexibility in how you create these markings, but they must result in durable, long-lasting designs. Paint, decals, or engraved blades are just some of the options that remain compliant, as long as the markings resist fading or falling off over time.

Pro Tip: Choose weather-resistant materials to preserve the readability of your vessel name and hailing port regardless of changing environmental conditions.
Why Proper Markings Are Crucial
Proper vessel markings go beyond fulfilling basic legal requirements. They enhance the vessel's traceability, ensure compliance with international maritime standards, and simplify maintenance related to its documentation status. Key benefits include:

Legal Compliance: Failure to meet USCG marking requirements could lead to penalties or rejection of your vessel’s documentation renewal process.
Ownership and Recovery: Proper markings prevent confusion in case of theft, ensuring authorities can identify your vessel and return it to you.
Professional Presentation: For businesses, visible and professional vessel markings convey reliability and professionalism to clients and regulators alike.

How to Change Vessel Name and Hailing Port
Need to rename your vessel or update its hailing port? The process is straightforward, but regulations must still be followed:

Submit the Correct Documentation: Use the official Change of Vessel Name and Hailing Port form, available online. Double-check your submission for formatting compliance before sending it to avoid delays.
Maintaining Compliance: The new name and hailing location must still meet all legal requirements outlined above regarding length, legibility, and distinctiveness.
Update Recorded Details: Ensure the updated markings match the legal records on file with the USCG to avoid discrepancies during inspections.

Note: Using any other form besides the specific change-of-name application form may result in the denial of the request, leading to unnecessary delays.
Laws Governing Vessel Documentation and Marking
Knowing the broader regulations surrounding vessel markings ensures that your vessel documentation remains valid.
Vessel Documentation Eligibility and Citizenship

Vessels of at least five net tons, wholly owned by U.S. citizens, are eligible for documentation.
For vessels used in fisheries or coastwise trade, documentation with valid endorsements is mandatory.

Authority and Enforcement
The USCG oversees all vessel documentation and marking practices. Vessels that do not comply with these regulations risk penalties such as fines or suspension of documentation credentials.
Frequently Asked Questions About Vessel Markings

Are there standardized dimensions for vessel name and hailing port markings?

Yes. All letters and numbers must stand at least four inches high and be clearly legible to comply with USCG requirements.

Can vessel markings be updated at any time?

Yes, vessel owners may update the name and hailing port at any time, but all changes must adhere to the established guidelines and include proper documentation.

Why does the official number need to be permanent?

Permanent markings ensure the vessel’s identification remains intact, even in cases of ownership change, theft, or disputes. Any attempt to alter the markings would cause visible damage, acting as a deterrent.

Can I have duplicate vessel names?

Yes, different vessels can share names, but the hailing port helps distinguish between them, providing clarity for identification purposes.

Can I Renew a Lost Certificate of Documentation?

Yes. Whether your COD has been misplaced, damaged, or stolen, you can document your vessel. Now, it may be too late to “renew” your Certificate of Documentation. Instead, you may need to reinstate it.

Losing critical documentation, such as a Certificate of Documentation (COD), can present challenges for vessel owners. A Certificate of Documentation is an essential document that ensures a vessel complies with U.S. Coast Guard regulations and verifies its usage and ownership details. Acting promptly is essential. Here at CG Portal, we can help streamline the process.
Replacement Before Renewal
A common question among vessel owners is whether it’s possible to renew a Certificate of Documentation after it has been lost. Unfortunately, the answer is no. If your original COD is lost, it cannot be directly renewed. Instead, you must first apply for a Replacement Certificate of Documentation (COD).
Why Replacement is Necessary
The U.S. Coast Guard mandates that vessel owners must have a valid, physical copy of their COD on board at all times. Operating a documented vessel without an actual certificate—even if it is within its valid period—is non-compliant with federal law. A photocopy or digital copy will not suffice in this case. Authorities require an official and complete replacement certificate.

At CG Portal, we make the replacement process as quick and straightforward as possible, helping you get back on the water while staying compliant.
How to Replace Your Certificate
To replace your lost COD:

Visit the Replacement Certificate of Documentation (COD) section on CG Portal’s platform.
Complete the application form, ensuring all details regarding the vessel and owner are accurate.
Submit the required processing fee associated with the replacement.

Need assistance? At our portal, you can follow the simple guidelines so as to guide you through this process step by step.
Certified Copies for Added Security
For added peace of mind, vessel owners also have the option of obtaining certified copies of their Certificates of Documentation. While these cannot replace the original in case of a loss, they are valid for ensuring compliance with authorities.

Certified copies can serve as an invaluable precaution if the original COD is damaged or misplaced. You can order certified copies through our portal, too.
Renewing a Certificate of Documentation
Once you’ve replaced your lost COD, the next important step is to ensure timely renewal. A COD is valid for one year from the issue date and must be renewed annually to remain valid. In some cases, the Certificate of Documentation can be renewed for up to five years in advance.
The Importance of Timely Renewal

Compliance: An expired COD can result in fines or restrictions on vessel operation. It’s critical to take the necessary steps each year to avoid disruptions.
Eligibility: Failing to renew your COD on time can lead to delays or the need to file for re-documentation, a process that requires additional paperwork and steps.

Streamlining the Renewal Process
At CG Portal, we understand that managing annual renewals can be an added burden for vessel owners, which is why we offer tailored solutions:

Automatic Renewal Options: Allowing you to prepay for up to five years of renewals, automatic renewals eliminate the hassle of remembering annual deadlines, giving you unparalleled peace of mind.
Quick Online Processing: Submit renewal applications directly through our easy-to-use platform, providing fast processing and tracking options.
Expert Support: Our document processors can find and fix any errors throughout the process.

Vessel Documentation Requirements
When it comes to vessel documentation, staying informed about federal regulations is just as important as adhering to renewal schedules. Below are key aspects of U.S. Coast Guard documentation requirements that vessel owners should know:
Eligibility for Documentation
To qualify for U.S. Coast Guard documentation:

The vessel must have a net weight of five tons or more.
It must be wholly owned by U.S. citizens. Exceptions may apply under limited circumstances, such as foreign trade or special agreements outlined under 46 U.S.C. 12118.

This documentation applies to vessels used both recreationally and commercially (e.g., those engaged in fisheries or coastwise trade).
Documentation Requirements
Certain vessel activities unequivocally require a COD:

Vessels engaged in fisheries within U.S. navigable waters or the Exclusive Economic Zone.
Vessels carrying out coastwise trade unless specifically exempt.

Failure to maintain documentation when required can result in penalties, making it imperative for eligible vessel owners to complete and keep up with their documentation processes.
Ownership and Citizen Compliance
For vessel owners, compliance extends beyond merely holding documentation:

A COD can only be issued if the vessel is wholly owned by United States citizens.
Partnerships, trusts, corporations, or associations owning vessels must all meet specific citizenship criteria as outlined by the U.S. Coast Guard (for example, certain equity and stock ownership thresholds for corporations).

Avoiding Mistakes in Vessel Documentation
Maintaining accurate records of your vessel’s ownership, operation, and documentation status is essential. Many challenges regarding lost CODs or failed renewals arise from misunderstandings or overlooking regulatory requirements. CG Portal services can simplify this process, helping you keep proper documentation at all stages.
FAQs About Replacing a COD

What happens if I lose my Certificate of Documentation before renewal?

Losing your COD before its renewal date requires you first to apply for a replacement. Only after obtaining the replacement can you proceed with routine renewals.

How soon can I replace a lost COD?

With CG Portal, we strive to expedite the replacement process. Once your application is complete, we work diligently to ensure minimal downtime for your vessel.

Is a replacement the same as a renewal?

Can I renew my COD automatically?

Yes, CG Portal offers automatic renewal options for up to five years in many cases, ensuring you never miss a deadline.

How much does it cost to replace or renew a COD?

At The Vessel Documentation E-Portal, our online tools make that easier than ever—especially with our convenient and secure Coast Guard search by name feature.



Whether you’re looking to confirm a vessel’s documentation status or begin the process of researching a vessel’s history, our Coast Guard search by name is a reliable starting point.
What is a Coast Guard Search by Name?
A Coast Guard search by name allows users to look up public documentation records for vessels registered with the United States Coast Guard (USCG). The Coast Guard maintains these records, which contain a range of important details about a documented vessel’s status.

Through The Vessel Documentation E-Portal, users can perform this type of search quickly and securely. All you need is the vessel name—or in some cases, other identifying information such as the official number—to begin your inquiry.
What Information Does the Coast Guard Search by Name Provide?
When you perform a Coast Guard search by name through our portal, you can access a detailed summary of available public data tied to the vessel in question. This information is pulled from the Coast Guard’s documentation database and may include the following:

Vessel Name: The officially documented name of the vessel.


Official Number: A unique identifier issued to the vessel by the USCG, which does not change even if ownership or registration changes.


Hull Identification Number (HIN): When available, this number adds another layer of identity verification.


Vessel Endorsement: This indicates what type of activities the vessel is legally permitted to engage in—whether recreational, commercial, fishing, or coastwise trade.


Hailing Port: The city and state listed on the Certificate of Documentation.


Vessel Dimensions: Including overall length, breadth, depth, gross tonnage, and net tonnage.


Issue Date of Certificate of Documentation: The exact date the current documentation was granted by the USCG.


Expiration Date: The date when the current Certificate of Documentation will no longer be valid if not renewed.



This search can provide peace of mind for vessel owners confirming their documentation is active, buyers researching vessels before purchase, or brokers performing due diligence for their clients.
Can I Only Search by Vessel Name?
No. While searching by vessel name is one of the most common methods, it is not the only option available through our platform.

Our Coast Guard search tool allows you to search by several key identifiers, including:

Vessel Name


Official Number


Hull Identification Number (if applicable)



The ability to search by multiple data points helps users who may only have partial information or who are looking to verify a vessel’s identity across more than one source.

You can begin a Coast Guard search by name or other identifiers directly through our secure platform here.
Why Would Someone Use a Coast Guard Search by Name?
There are many reasons individuals and companies choose to use a Coast Guard search by name through our portal. Some of the most common include:

Verifying Documentation Status: Before making a purchase or entering into a contract involving a vessel, it's important to ensure the vessel’s documentation is up-to-date.


Confirming Endorsements: Understanding what a vessel is legally permitted to do can influence business decisions, insurance policies, and operational planning.


Checking Expiration Dates: Vessel owners often use the tool to double-check the expiration date of their documentation to avoid lapses.


Due Diligence for Financing or Charters: Financial institutions, charter companies, and brokers use this data to assess risk and eligibility.


General Research or Historical Interest: Maritime historians, journalists, and enthusiasts may use this data to track vessels of interest or to gather background information.



What Information Is Not Included in the Search?
While the Coast Guard search by name can provide a wealth of valuable data, there are important limitations to understand. Notably, this type of search does not include private or financial information, such as:

Current or Previous Owners: Ownership records are considered private and are not listed in public search results.


Liens or Mortgages: Any financial encumbrances or claims against the vessel—such as a Preferred Ship Mortgage—will not appear in a standard vessel search.


Chain of Title: You won’t find any ownership history or transfer records.



If you need any of the above information, the correct step is to request an Abstract of Title.
What Is an Abstract of Title?
An Abstract of Title is a more in-depth legal document that provides a complete recorded history of a documented vessel. Unlike a basic Coast Guard search by name, an Abstract includes:

Ownership History: A list of all recorded owners over time.


Recorded Mortgages and Liens: Information about any Preferred Ship Mortgages, releases, or other financial encumbrances.


Transfer Records: Details about when and how ownership was transferred, including legal instruments used.


Satisfactions and Releases: Confirmation that liens or mortgages have been discharged or satisfied.



If you need to determine whether a vessel is free of liens or has a clean title, the Abstract of Title is the correct document to request.

The good news? You can apply for one easily through The Vessel Documentation E-Portal. Our system allows you to complete your Abstract request online, and we’ll handle the submission process for you.

What If the Vessel I’m Searching For Doesn’t Appear?
There are several reasons a vessel might not appear in your search results:

The vessel is not documented: Only documented vessels appear in this database. State-registered vessels without federal documentation will not show up.


Incorrect search data: A misspelled vessel name or incorrect number may yield no results. Be sure to double-check what you’ve entered.


Recent documentation updates: If the vessel was just documented, the Coast Guard’s database may not yet reflect the changes.



If you’re unsure whether the information you have is correct, try searching with multiple identifiers or consult your broker, seller, or lender for accurate data.
