Coast Guard Requirements for Documentation: Definite Guide

Have you been trying to figure out whether or not you should document your vessel? Does it seem as if the Coast Guard requirements for documentation are confusing? We can help. Here at the Vessel Registrar Center, we make it easier to not just document your vessel, but to determine whether or not documentation is right for you. 

Coast Guard documentation requirements

Documentation serves as proof of nationality for a vessel, allowing it to travel internationally under the U.S. flag. Beyond international recognition, documented vessels enjoy certain benefits, such as preferred mortgage recording, which can simplify financing. While not all boats must be documented, those that meet specific Coast Guard requirements for documentation often find it advantageous for legal and operational purposes. We can help you to find as well as complete these forms and others. 

The History and Importance of Vessel Documentation

Vessel documentation in the United States dates back to the 11th Act of the First Congress in 1789, which authorized the federal registration of ships for economic and national security purposes. 

Initially, documentation was used to distinguish American vessels engaged in foreign trade, ensuring they received legal protections and trade privileges. Over time, the system evolved, and today, the U.S. Coast Guard manages vessel documentation as a means of verifying ownership, enforcing maritime laws, and maintaining safety standards.

At our portal, we make it easier to complete and apply for the forms you may need. 

Vessels That Must Be Documented

The U.S. Coast Guard requires mandatory documentation for vessels that meet specific criteria based on size, tonnage, and commercial use. The primary determining factor is whether a vessel measures at least five net tons—a volumetric measurement, not weight—which generally applies to boats 25 feet or longer.

Commercial vessels operating in coastwise trade (transporting goods or passengers between U.S. ports) or fisheries must be documented if they meet the tonnage threshold. Additionally, any vessel seeking a preferred ship mortgage must be documented, as this federal process provides lenders with stronger security interests.

Optional Documentation for Recreational and Other Eligible Vessels

Many boat owners choose voluntary documentation even when not legally required. Recreational vessels that meet the five-net-ton threshold can opt for documentation, which offers advantages such as:

  • Simplified international travel – Documented vessels receive a Certificate of Documentation (COD), recognized globally as proof of U.S. nationality, making customs clearance easier in foreign ports.
  • Enhanced resale value – A documented vessel has a clear, federally recognized ownership record, which can streamline sales transactions.
  • Financing benefits – Lenders often prefer documented vessels because of the ability to record preferred mortgages with the Coast Guard.

Detailed Eligibility Criteria

To qualify for Coast Guard documentation, a vessel must meet several key requirements:

  1. U.S. Ownership – The boat must be wholly owned by a U.S. citizen or a U.S.-based entity. Corporations and partnerships must meet specific citizenship requirements, with at least 51% U.S. ownership.
  2. Tonnage Measurement – The vessel must measure at least five net tons. Remember: this is calculated using a Coast Guard-approved formula based on internal volume, not displacement weight.
  3. Previous Documentation Status – If the vessel was previously registered in another country, it must be formally deregistered before U.S. documentation can proceed.
  4. Intended Use – While commercial vessels have stricter requirements, recreational boats must still comply with federal regulations regarding proper markings and adherence to safety standards.
