What Is the Jones Act? A Guide for Yacht Owners

Passed as the Merchant Marine Act of 1920, The Jones Act is the federal law governing U.S. coastwise trade: it requires that goods moved between American ports travel on U.S.-built, U.S.-owned, U.S.-flagged, and U.S.-crewed vessels, and it gives maritime workers the legal right to seek compensation for on-the-job injuries. Whether you’ve encountered the term in shipping, boating, or insurance conversations, its implications are wide-reaching, particularly if you’re a yacht owner or maritime professional with captain and crew exposures.

Below, we explore key aspects of the Jones Act to help you understand your obligations, protect your crew, and ensure compliance with this federal law.

What Is the Jones Act?

In simplest terms, the Jones Act is a federal law designed to protect U.S.-flagged vessels, their operators, and their crews. It governs coastwise trade and establishes specific requirements for ships operating between U.S. ports or conducting domestic trade. It was enacted by the U.S. Congress to stimulate the shipping industry in the wake of World War I.

Here are some basic principles of the law:

• U.S.-built ships must transport goods or passengers between U.S. ports.
• Companies operating under the Jones Act must employ U.S. citizens or permanent residents.
• The Act prioritizes the interests of the American Merchant Marine and national security in a global shipping industry.

What Are the Four Requirements of the Jones Act?

The Jones Act’s coastwise trade provisions are codified at Section 27 of the Merchant Marine Act of 1920, also cited as 46 U.S.C. §55102. This is the section most relevant to vessel operators. It establishes the four requirements any vessel must meet to legally transport merchandise between U.S. ports.

1. U.S.-Built: The vessel must have been constructed at a U.S. shipyard within the U.S.
2. U.S.-Owned: The vessel must be owned by U.S. citizens or U.S.-controlled entities that meet federal ownership thresholds.
3. U.S.-Flagged: The vessel must fly the U.S. flag and be documented under U.S. law as a U.S. flag ship.
4. U.S.-Crewed: The vessel must be operated by U.S. citizens or lawful permanent residents.

These four requirements are part of the broader framework of cabotage laws, regulations that restrict domestic maritime trade to a nation’s own vessels. Most developed countries maintain some version of cabotage legislation. The Jones Act is the United States’ primary cabotage statute for coastwise trade, and it applies to commercial shipping, product tankers transporting crude oil and petroleum products, dredging, towing, and offshore activities including offshore wind farms.

Who Enforces the Jones Act?

Three federal agencies share responsibility for Jones Act enforcement.

• Customs and Border Protection (CBP) is the primary authority. CBP reviews vessel documentation, ownership records, and crew composition before permitting a vessel to engage in coastwise trade. Violations can result in vessel seizure and substantial financial penalties.
• The U.S. Coast Guard enforces safety and documentation standards for U.S.-flagged vessels, including verification that vessels satisfy the seaworthiness and crewing requirements of the Act.
• The U.S. Maritime Administration (MARAD), an agency within the Department of Transportation, administers Jones Act waiver requests and provides compliance guidance. MARAD coordinates with the Department of Homeland Security on national security matters related to the domestic fleet.

Yacht owners with a captain and crew are most likely to encounter CBP during crew documentation reviews and the U.S. Coast Guard during vessel inspections.

How the Jones Act Affects Your Responsibilities as a Yacht Owner

For yacht owners, one of the most critical aspects of the Jones Act is its focus on safety and working conditions for maritime workers. Let’s take a closer look at how this legislation can impact your responsibilities as a yacht owner.

1. Captain/Crew Protections

The Jones Act gives maritime workers specific legal rights, including your yacht’s captain and crew. If a crew member sustains injuries while working on your vessel, they have the right to file claims for compensation covering medical expenses, lost wages, and pain and suffering.

Crew dissatisfaction that goes unaddressed can escalate into legal claims. Protecting your crew is both a legal obligation and a practical one for any professional vessel operation.

Key Tip: Make sure your insurance policy provides comprehensive captain/crew coverage to meet these obligations.

2. Liability and Negligence

Under the Jones Act, yacht owners can be held responsible for injuries caused by negligence or unsafe conditions on board. This means it’s your responsibility to:

• Ensure proper safety measures are in place.
• Conduct routine inspections for potential hazards.
• Maintain your vessel’s overall seaworthiness.

Failing to operate a safe and secure yacht puts your crew at risk and exposes you to expensive legal claims.

Insurance Tip: Many yacht insurance policies offer liability protections to reduce financial risks from negligence claims. Speak to a marine insurance professional to ensure your yacht’s policy includes this crucial coverage.

3. Maintenance and Cure

One of the essential provisions of the Jones Act is the requirement to provide “maintenance and cure” for injured crew members.

• Maintenance covers the crew member’s daily living expenses while recovering.
• Cure pays for their medical treatment until they reach maximum medical improvement (MMI).

This obligation applies regardless of fault, so even if the crew member’s injury wasn’t caused by negligence, as a yacht owner, you’re still responsible. Coverage for maintenance and cure claims protects the financial sustainability of your vessel’s operation.

4. Obligation to Provide Captain/Crew Coverage

Providing comprehensive insurance coverage for your captain and crew isn’t optional—it’s a legal and moral obligation.

This coverage should include protection for:

• Injury due to negligence
• Claims about safety in the work environment
• Claims for lost wages, pain and suffering, or disability
• Maintenance and cure obligations
• Third-party passenger liability, if applicable

By ensuring proper insurance coverage, you safeguard your crew’s well-being and protect your financial interests.

Proactive Measure: Consult an experienced marine insurance provider to create a policy tailored to your yacht’s unique needs.

5. Jones Act Requirements for Vessels

While the Jones Act’s scope is broadest for commercial vessels, its crew protection provisions and seaworthiness standards extend to yacht owners with captain and crew. The coastwise trade requirements apply across dredging, towing, crude oil and petroleum product transport, and emerging sectors such as offshore wind farms. The law applies not only along the continental U.S. coastline but also in U.S. territories including Puerto Rico, Hawaii, Alaska, and Guam.

6. Seaworthiness Requirement

The Jones Act includes an implied warranty of seaworthiness, meaning that as a yacht owner, you are obligated to ensure that your vessel is reasonably fit for its intended use. This includes keeping the vessel safe for the captain/crew to work on.

If a captain/crew member is injured due to the vessel’s unseaworthiness, they may have grounds to file a negligence claim for which the yacht owner would be liable. In some instances, a judgment could be placed against the vessel itself.

7. Economic and Security Implications

The Jones Act was built around two parallel purposes: protecting maritime workers and maintaining a domestic commercial fleet capable of supporting national security needs. The U.S. Navy and Department of Defense rely on civilian merchant mariners and U.S.-flagged vessels for sealift and logistics operations. U.S. shipyards that build Jones Act-compliant vessels support tens of thousands of American jobs in domestic shipbuilding. The U.S. Maritime Administration tracks fleet capacity and workforce levels as part of national defense planning, alongside its broader mission of supporting the maritime sector and economic security.

The Act has not been without controversy. Critics, including the Cato Institute and the late Senator John McCain, argue that requiring U.S.-built and U.S.-crewed vessels raises shipping costs and places a disproportionate burden on U.S. territories such as Puerto Rico, Guam, Hawaii, and Alaska, where residents depend heavily on maritime freight. Senator McCain introduced legislation to repeal the Act multiple times. Those efforts did not succeed, but they kept the shipping cost debate in front of Congress.

Temporary Jones Act waivers have been issued during national emergencies, most notably following Hurricane Katrina in 2005 and Hurricane Maria in 2017, to allow foreign-flagged vessels to assist with fuel and relief supply delivery. The Department of Homeland Security has authority to issue emergency waivers, while MARAD handles standard waiver requests outside of emergency conditions. Waivers are temporary, limited in scope, and do not alter the underlying law.

Supporters of the Act counter that maintaining a domestic fleet and domestic shipbuilding capacity is a defensible investment in national defense, American jobs, and the long-term resilience of the U.S. maritime industry.

8. Consequences of Not Providing Coverage

Failing to meet your obligations as stipulated under the Jones Act can result in:

• Costly lawsuits from crew members seeking compensation.
• Personal liability, with significant out-of-pocket expenses.
• Consequences that may financially jeopardize your vessel’s operation.

Understanding your responsibilities and carrying adequate insurance coverage are the two most direct ways to protect against those outcomes.
