What size vessel qualifies for USCG documentation?

Vessels of at least 5 net tons owned entirely by U.S. citizens may qualify. For typical fiberglass powerboats, 5 net tons roughly equates to 25–27 feet LOA. Sailboats and vessels with large cabins may qualify at shorter lengths.

Do I still need state registration if I have USCG documentation?

In most states, yes. USCG documentation replaces the state title but does not always replace state registration. Many states require documented vessels to display a current state registration decal and registration number. Check your state's specific requirements.

How do I search liens on a USCG-documented vessel?

Order an Abstract of Title from the National Vessel Documentation Center (NVDC) at nvdc.uscg.mil. The abstract shows all recorded mortgages, encumbrances, and ownership history on the vessel.

USCG Vessel Documentation

Benefits of USCG Documentation

International Recognition

A COD is recognized by foreign port authorities and customs agencies worldwide — essential for bluewater cruising or offshore fishing.

Preferred Mortgages

Most marine lenders require USCG documentation to record a preferred ship's mortgage. Without it, boat financing is significantly harder.

Federal Lien Search

All encumbrances on documented vessels must be recorded with the NVDC, providing a reliable national lien database unavailable for state-titled vessels.

Name the Vessel

Only USCG-documented vessels may display an official vessel name on the hull (in addition to the hailing port). State-registered boats use a registration number instead.

Commercial Operations

Vessels used for hire (charter fishing, passenger service, commercial freight) on navigable U.S. waters are legally required to be USCG documented.

Ownership History

The NVDC maintains a chain-of-title going back to when the vessel was first documented — a valuable transparency feature for buyers.

How to Apply for USCG Documentation

1
Confirm eligibility
Your vessel must be at least 5 net tons. For most fiberglass powerboats, this means roughly 25–27 feet LOA. All owners must be U.S. citizens or qualifying U.S. entities.
2
Gather documents
You'll need: the builder's certificate (for new vessels) or a chain of bills of sale back to the original, evidence of citizenship for all owners, and a completed CG-1258 application.
3
Submit to the NVDC
Submit your application online via the National Vessel Documentation Center (nvdc.uscg.mil) or through an authorized documentation processing service. Pay the applicable fee.
4
Mark the documentation number
Once approved, permanently mark your USCG documentation number on the interior of the hull — block numerals at least 3 inches high, in a contrasting color.
5
Keep your COD aboard
The Certificate of Documentation (COD) must be kept aboard the vessel at all times when underway. U.S. Customs and Coast Guard officers may request it.
6
Renew annually
CODs expire every year. You'll receive a renewal notice from the NVDC. Renew before expiration to avoid operating with an invalid certificate.

Lien Search for Documented Vessels

Before buying a USCG-documented vessel, always order an Abstract of Title from the NVDC. This document shows the complete ownership history and all recorded mortgages and encumbrances against the vessel.

Unlike state lien systems — which only cover vessels registered in that state — the NVDC abstract covers the entire history of the documented vessel regardless of where it was kept or used.

The NVDC is the official U.S. Coast Guard documentation database.

Buying a USCG-Documented Vessel

When purchasing a documented vessel, you don't receive a state title — you receive a signed bill of sale and the current Certificate of Documentation (or a chain of bills of sale if the COD has expired). You then file with the NVDC to transfer documentation into your name.

Important: A documented vessel's lien history is maintained at the federal level, not your state DMV. Always order an NVDC Abstract of Title before purchase — state-level lien searches will not show preferred mortgages recorded against documented vessels.

Frequently Asked Questions

What is USCG vessel documentation?▾

USCG documentation is a federal Certificate of Documentation (COD) issued by the National Vessel Documentation Center. It serves as the vessel's federal title, is internationally recognized, and is required for commercial vessels on navigable U.S. waters.

What size vessel qualifies?▾

Vessels of at least 5 net tons owned entirely by U.S. citizens. For typical fiberglass powerboats, 5 net tons is roughly 25–27 feet LOA. Larger displacement hulls may qualify at shorter lengths.

Do I still need state registration?▾

In most states, yes. USCG documentation replaces the state title but most states still require documented vessels to display a state registration decal and pay annual or biennial registration fees. Check your state guide for specifics.

How do I search liens on a documented vessel?▾

Order an Abstract of Title from the NVDC at nvdc.uscg.mil. It shows all recorded preferred mortgages, encumbrances, and the complete ownership chain.

What is a preferred ship's mortgage?▾

A preferred ship's mortgage is a lien recorded at the NVDC on a documented vessel. Most marine lenders require USCG documentation to secure boat financing, since preferred mortgages have federal priority and are enforceable under admiralty law.
