Who Qualifies as a Seaman Under the Jones Act?

The Jones Act provides important legal protections for seamen who are injured while working in the service of a vessel. However, simply working on or around the water does not automatically make someone a “seaman” for purposes of the Jones Act. Determining seaman status can be one of the most important issues in a maritime injury case because it can affect what legal remedies are available to an injured worker.


The U.S. Supreme Court has established a fact-specific test for determining who qualifies. Generally, a worker's duties must contribute to the function or mission of a vessel, and the worker must have a substantial connection to a vessel in navigation or an identifiable group of vessels.


At Biggs & Gunst P.C., we represent injured maritime workers and help them understand which federal maritime protections may apply to their circumstances. Our maritime attorneys bring firsthand knowledge of the maritime industry to these cases, allowing us to understand both the legal issues and the realities of working aboard commercial vessels.


What Does It Mean to Be a Seaman Under the Jones Act?

There is no single job title that determines whether a maritime worker qualifies as a seaman. Instead, courts look at the nature of the worker's duties and relationship with a vessel.


Under the test established by the U.S. Supreme Court, a worker's duties must first contribute to the function of a vessel or the accomplishment of its mission. This requirement is intentionally broad. The second requirement is that the worker have a connection to a vessel in navigation—or an identifiable group of vessels—that is substantial in both its duration and nature.


This means that deckhands, officers, engineers, cooks, and other crew members may qualify for Jones Act protection when their work and connection to a vessel satisfy the applicable requirements. Biggs & Gunst P.C. identifies these types of crew members among the seamen who may receive Jones Act protections.


Because every maritime job is different, determining whether someone qualifies should involve a careful examination of their actual duties rather than relying solely on their job title.


How Much Time Must You Spend on a Vessel?

Time spent working aboard a vessel can be an important factor in determining seaman status. The Supreme Court has stated that, as a general rule of thumb, a worker who spends less than approximately 30% of their working time in the service of a vessel in navigation ordinarily should not qualify as a seaman.


However, the 30% figure is a guideline rather than an automatic rule. Seaman status is fact-specific, and courts may consider the nature of the vessel, the employee's precise relationship with it, and other circumstances surrounding the worker's employment.


This distinction can become particularly important for workers who divide their time between vessels and shore-based responsibilities. At Biggs & Gunst P.C., our maritime attorneys can review your employment history and job responsibilities to help determine whether you may qualify for protection under the Jones Act.


Does the Vessel Have to Be at Sea When You Are Injured?

A Jones Act case is not necessarily limited to an accident that occurs while a vessel is actively traveling at sea. Biggs & Gunst P.C. notes that an injured seaman may potentially pursue compensation even when the vessel was docked at the time of the incident.


The worker's overall relationship with the vessel is therefore important. In Chandris, Inc. v. Latsis, the Supreme Court explained that whether a vessel is “in navigation” is a fact-intensive question and that time spent aboard a vessel in drydock could not simply be excluded from consideration under the circumstances of that case.


If you suffered an injury while your vessel was docked, undergoing certain repairs, or otherwise not actively underway, you should not automatically assume that the Jones Act does not apply. A maritime attorney can evaluate the facts and determine which laws may govern your claim.


What Workers May Not Qualify as Seamen?

Not everyone who works in the maritime industry is covered by the Jones Act. The Supreme Court's seaman-status test is designed in part to distinguish sea-based crew members from land-based maritime employees who have only a temporary or sporadic connection with a vessel.


A harbor or waterfront employee who does not qualify as a Jones Act seaman may potentially have rights under another federal maritime law, such as the Longshore and Harbor Workers' Compensation Act (LHWCA). Biggs & Gunst P.C. recognizes that harbor workers who fall outside Jones Act coverage may instead have a claim under the LHWCA.


Determining which law applies is critical because different maritime laws provide different rights and procedures. If your employment does not fit neatly into one category, Biggs & Gunst P.C. can evaluate your work duties and circumstances to identify the potential legal options available to you.


What Benefits Can a Qualifying Seaman Pursue?

Qualifying as a seaman can provide important protections when an injury occurs. Under the Jones Act, an injured seaman may have the right to bring a negligence claim against an employer. Depending on the circumstances, compensation may include medical expenses, lost wages, loss of earning capacity, future medical expenses, and damages related to pain and suffering.


Injured seamen may also have rights to maintenance and cure. These maritime benefits generally relate to living expenses and necessary medical treatment while an eligible seaman recovers, subject to applicable maritime law.


A serious vessel injury can affect your health, income, and ability to continue your maritime career. Understanding all potential sources of recovery can therefore be an important part of protecting your future.
