Ship Mortgage: Recording, Preferred Status, and Foreclosure

A preferred ship mortgage under U.S. law requires three things working together: a vessel that is eligible, a mortgage instrument that contains what the statute demands, and proper recording with the U.S. Coast Guard. Meet all three, and the lender holds a federal lien enforceable in admiralty court that outranks nearly every competing claim against the boat. Miss any one, and the arrangement drops back to ordinary state commercial law with weaker remedies. The rules come from Chapter 313 of Title 46 of the U.S. Code, the modern codification of the Ship Mortgage Act of 1920.¹

Which Vessels Are Eligible

Not every boat qualifies. The vessel must be documented with the U.S. Coast Guard, which requires that it measure at least five net tons, be wholly owned by eligible U.S. persons or entities, and not be documented under the laws of a foreign country.² A boat without this federal documentation cannot carry a preferred ship mortgage.

One alternative exists. A mortgage on a vessel titled through a state system can qualify as preferred if the Secretary of Homeland Security has certified that the state’s titling system meets federal guidelines and vessel information is shared with the Secretary under federal reporting requirements.³ Outside those two paths, any security interest in a vessel falls back to state law, typically UCC Article 9, with no access to federal admiralty enforcement.

What the Mortgage Instrument Must Contain

The document itself has to satisfy six statutory content requirements before the Coast Guard will accept it for filing. Under 46 U.S.C. § 31321(b), the mortgage must:⁴

Identify the vessel, typically by official number, name, or hull identification number.
State the name and address of each party to the instrument.
State the direct or contingent obligations secured by the mortgage, excluding interest, expenses, and fees.
Describe the mortgagor’s interest in the vessel.
Describe the interest being conveyed as security.
Be signed and acknowledged by the vessel owner, with a notarization or equivalent legal acknowledgment.

The statute lets the secured amount cover contingent obligations, not just a fixed dollar figure. That matters for revolving credit lines or other arrangements where the outstanding balance moves.

One further condition sits outside that list but does the heavy lifting on status. To achieve preferred status, the mortgage must cover the “whole of the vessel.”³ A partial-interest mortgage can still be filed and recorded, but it will not be treated as preferred, which meaningfully weakens the lender in any priority fight.

Filing and Recording With the Coast Guard

Drafting the document is only half the work. To gain protection against third parties, the lender must record the instrument with the Coast Guard’s National Vessel Documentation Center (NVDC).⁵ The mortgage becomes valid against all persons from the moment it is filed with the Secretary, and that filing date sets its place in the priority line.⁴

The recording fee is $4.00 per page.⁶ Submitters may attach an optional application form (CG-5542) to the mortgage; when it is properly completed, the NVDC will file and record the instrument without further review, which speeds the process.⁵ The Coast Guard cannot accept a mortgage for filing unless the vessel already has a valid Certificate of Documentation or a pending application for initial documentation on file.

When multiple preferred mortgages sit on the same vessel, the Secretary records them in the order filed, and each becomes valid from its own filing date.⁴ Earlier recordings outrank later ones.

What Preferred Status Gives the Lender

The reason to jump through these hoops is priority. In a court-ordered sale, the preferred mortgage lien outranks all claims against the vessel except three categories: court-allowed expenses and fees, court-imposed costs, and preferred maritime liens.⁷ That places the mortgage holder ahead of general creditors, state-law security interests, and most maritime liens, including liens for fuel, repairs, and other necessaries supplied after the mortgage was recorded.

The claims that do outrank a preferred mortgage are narrowly defined. Under 46 U.S.C. § 31301, a “preferred maritime lien” is a maritime lien in one of six categories: any maritime lien arising before the preferred mortgage was filed; damages arising out of a maritime tort; wages of a stevedore employed directly by the vessel’s operator; wages of the crew; general average contributions; and salvage, including contract salvage.⁸ The people who work on the vessel, rescue it, or are harmed by it get paid before the bank. Everything else stands behind.

Enforcement When the Borrower Defaults

If the borrower defaults, federal law gives the lender a primary remedy: an in rem action in federal district court sitting in admiralty, filed directly against the vessel rather than against the borrower personally.⁹ Federal district courts have exclusive jurisdiction over these actions; state courts cannot hear them. If the conditions appear to exist, the court issues a warrant, and the U.S. Marshal arrests the vessel, which is what gives the court jurisdiction over the case.¹⁰

A court sale usually follows. Every existing claim against the vessel terminates on the date of sale, and the buyer takes clean title.⁷ Terminated claims attach to the proceeds and are paid in priority order: court costs and expenses, then preferred maritime liens, then the preferred mortgage, then everything else.

If the sale falls short of the debt, the lender is not stuck. The statute expressly authorizes a separate in personam action in admiralty against the borrower, any maker, comaker, or guarantor for the outstanding balance or any deficiency, and also permits a non-admiralty civil action against those same parties.⁹ A vessel owner whose boat sells for less than the mortgage balance can still be personally liable for the shortfall. The statute also allows “any other remedy” under applicable law, provided it does not violate federal restrictions on vessel transfers.

Discharging the Mortgage Once Paid

When the debt is fully paid, the lender must file a satisfaction or release with the NVDC. The document must identify the vessel by name and official number, name each mortgagor and mortgagee, state the total mortgage amount, and identify the specific recorded mortgage being released (typically by book and page or batch and document ID). It must be signed by or on behalf of each mortgagee, dated, and notarized.¹¹

A lender that fails to file the discharge after full payment faces a civil penalty of up to $10,000 under 46 U.S.C. § 31309 and § 31321(f). An uncleared mortgage on the documentation record freezes the title: a new owner cannot transfer or re-document the vessel until the record is cleared. If you have paid off a vessel mortgage, confirm with the NVDC that the satisfaction has been recorded rather than trusting that the lender handled it.
