What is the Merchant Marine Act of 1920?


The Merchant Marine Act of 1920, more commonly known as the Jones Act, is a law the U.S. Congress passed to protect maritime workers such as fisherman, offshore oil rig employees and shipping industry crew members. It was named for Sen. Wesley R. Jones, the act’s sponsor.

The Jones Act is a form of maritime admiralty law that ensures workers have safe, hazard-free working environments and that they are taken care of in the event of injury or harm. Additionally, the Merchant Marine Act of 1920 covers cabotage, which established regulations for how cargo and passengers can be transported between U.S. ports.

How the Merchant Marine Act of 1920 Protects Workers

The Jones Act provides protection for maritime workers in a number of ways. First, it requires that all ship owners provide a safe and secure seaworthy vessel for all crew members to live and work on. This means equipment, structural components and onboard machinery must be maintained and kept in working order. Additionally, there must be safety policies and procedures in place on the vessel to protect workers and crew members.

Ifa worker is injured while working on the vessel, the Jones Act maritime admiralty law ensures they are taken care of with maintenance and cure benefits. Maintenance and cure benefits help the victim by paying for medical bills and treatments, as well as daily living costs until the point of maximum medical improvement.

It is an employer’s legal obligation to offer maintenance and cure benefits until the point of maximum medical improvement. If you are injured and your employer denies you these benefits for any reason, you may have grounds for a legal claim under the Jones Act.

How the Merchant Marine Act Protects U.S. Waters 

The act includes a cabotage provision that addresses how goods and passengers are to be shipped on U.S. waters. Specifically, it states that:

  • the vessel used to move cargo or passengers be controlled and owned by a U.S.-based company, at least 75%
  • the vessel’s crew must be at least 75%American
  • the vessel must be built (or rebuilt) in the U.S.
  • the vessel must be registered in the U.S.

The History of Jones Act Law

Until the early 20th century, sailors and other sea workers had a limited amount of rights. Even if a seaman suffered terrible injuries because of the carelessness of an employer, he had no power to file a lawsuit. General maritime law only allowed for basic maintenance and cure benefits, which provides a small allowance and reasonable medical attention for seafaring employees.

The Supreme Court only reinforced the disadvantages seamen faced whenever they endured injuries while at sea. Based on its rulings, employers had the ability to shift any blame for ship accidents on other workers and not take any responsibility at all.

But after the sinking of the Titanic in 1912 and an awareness of the vulnerability of merchant marines in World War I, Congress became more open to examining seamen’s rights.

Over time, Congress opened up new opportunities for ship workers to attain justice. But even when the Merchant Marine Act became law in 1920, there was still the question of who qualified as seamen. The definition evolved throughout the decades. Yet it wasn’t until 1995 that any real clarification took place, expanding Jones Act law to give seamen the right to sue, even if their work entailed going ashore.

Amending the Jones Act

The Jones Act has been subject to much controversy over the years. And due to the outcomes of several important maritime cases, amending the Jones Act has been a hot-button issue.

Amendments to the Act have included:

  • The Longshoreman’s and Harbor Workers Compensation Act – Passed in 1927, this aimed to help define the term “seaman,” as originally used in the Jones Act and to better clarify to whom the Act applied.
  • South Chicago Coal & Dock Co. v. Bassett – Following this case, legislation was passed that declared a maritime worker was not considered a “seaman” if his or her work did not relate to the navigation of the ship.
  • Gianfala v. Texas Co. – In response to this 1955 case, the Supreme Court further clarified the term “seaman” to cover offshore oil rig laborers.
  • Chandris, Inc. v. Latsis – In trying this case in 1955, two elements were defined that would determine if a plaintiff could be covered by the Jones Act: 1) if he or she contributed to the function of the vessel or to the accomplishment of its mission and 2) if he or she had a substantial and enduring connection to the vessel in navigation. These changes allowed maritime workers to sue for injuries even if their work was offshore.
  • Recodification – After years of amending the Jones Act, the legislation was completely redrafted and re-codified in 2006. It was signed into law by President George W. Bush.
