The Jones Act is a crew member’s negligence claim against the employer
The Jones Act is the federal statute that lets a seaman injured in the course of employment bring a negligence action against the employer, with the right to a jury. If the seaman dies from the injury, the personal representative may bring the action. The statute borrows the rules that govern injured railroad workers, including the general rule that a worker’s own carelessness reduces a recovery rather than barring it.
Two things follow that people are often not told. The claim runs against the employer, which is not always the company that owns the vessel. And the claim belongs only to a seaman, a word the statute does not define. Whether a particular worker is a seaman is the first question in every Jones Act matter, and it is a legal conclusion reached from the facts of the worker’s employment.
Those questions and the two other remedies available to seamen are reviewed alongside the investigation of the vessel incident and the records it left.
Seaman status is decided from duties, not job titles
The Supreme Court has set two requirements. The worker’s duties must contribute to the function of the vessel or the accomplishment of its mission, and the worker must have a connection to a vessel in navigation, or to a fleet of vessels under common ownership or control, that is substantial in both its duration and its nature. The inquiry looks at the worker’s whole employment: a land-based worker does not become a seaman by being aboard a vessel when hurt, and a seaman does not stop being one while the vessel’s work takes them ashore.
Federal appellate law for this region adds questions about the nature of the connection. They ask whether the worker owes allegiance to the vessel rather than simply to a shoreside employer, whether the work is sea-based or involves seagoing activity, and whether the worker’s assignment was a discrete task after which the connection ended, or instead involved sailing with the vessel from place to place. A welder assigned to a rig for one job and an engineer who lives aboard for hitches can both spend most of their time on vessels and still be in different positions.
There is a widely repeated rule of thumb about the share of a worker’s time spent in the service of a vessel. It is a guide courts use, not a line a worker can apply to themselves, and cases have turned on the nature of the connection even where the time was substantial. A percentage alone cannot establish status, and we do not ask you to classify yourself.
The vessel question
A Jones Act claim needs a vessel in navigation. Federal law defines a vessel as any watercraft or other artificial contrivance used, or capable of being used, as a means of transportation on water, and the Supreme Court has read that to include structures practically capable of carrying people or things over water regardless of their primary purpose or whether they were moving. A structure permanently moored, or otherwise rendered practically incapable of transportation, is treated differently.
Tugs, towboats, barges, crew boats, supply vessels, dredges, and fishing vessels are vessels in the ordinary sense. Courts have also analyzed jack-up drilling rigs, semisubmersibles, and drillships as vessels, including rigs that were jacked up on the seabed at the time of the work. A fixed production platform is not a vessel; it is treated as an artificial island, and injuries on one raise offshore accident questions. Identifying the structure, its documentation, and what it was doing is therefore part of the status review, not a detail that comes later.
Three separate claims: negligence, unseaworthiness, and maintenance and cure
A seaman has three distinct remedies, and they are owed by different parties on different terms.
- Jones Act negligence. A claim against the employer for negligence that caused the injury, tried to a jury if the seaman elects.
- Unseaworthiness. A claim against the vessel’s owner for a vessel, its equipment, or its crew that was not reasonably fit for its intended purpose. The Supreme Court has described the owner’s duty as absolute and independent of the Jones Act duty of care, and the owner’s knowledge of the condition is not required.
- Maintenance and cure. The employer’s obligation to provide food, lodging, and medical care to a seaman who is injured or falls ill while in the ship’s service, without regard to fault, until maximum medical cure is reached—the point at which further curative treatment is not expected to improve the condition. That is not the same as permanent impairment, the end of all medical care, or maximum medical improvement under another system. Courts resolve doubts about maintenance and cure in the seaman’s favor.
A company that is paying maintenance is meeting one obligation; it is not resolving the others. The firm treats a maintenance-and-cure payment history as a record to review, not as a settlement of the case, and it does not publish rates, categories of damages, or the outcomes of other matters.
Who the employer is
On many vessels the person who signs the paycheck, the company that operates the vessel, and the customer who directed the work are three different organizations. A staffing or crewing company may employ a deckhand who works under a vessel operator’s captain aboard a vessel owned by a leasing company and chartered to an energy company. The Jones Act claim runs against the employer; unseaworthiness runs against the owner; maintenance and cure is owed by the employer.
Which company is the employer for these purposes is a legal question answered from the crewing agreements, charter parties, and master service agreements, and from who actually directed the work. The firm requests those contracts early, because they also allocate responsibility among the companies in ways the worker may never have seen.
Records that establish a crew member’s connection to the vessel
Courts have decided seaman status by counting days: how many the worker spent aboard which vessels, doing what, at whose direction. The records that answer those questions are held by the employer and the vessel operator.
- Payroll and timekeeping broken down by vessel and location, assignment and dispatch records, hitch schedules, and travel and per-diem records.
- Crew lists, watch schedules, and the employer’s assignment history across its fleet over the preceding year.
- The vessel’s Certificate of Documentation and Certificate of Inspection, class records, and whether the unit was underway, moored, jacked up, or in drydock.
- Deck, engine, and official logs, job safety analyses and permits, safety-management documents, and maintenance and inspection records for the equipment involved.
- The casualty report the vessel’s owner or operator files with the Coast Guard for defined casualties, and the company’s internal incident report and any drug and alcohol testing.
- The maintenance-and-cure file: payments, cure authorizations and denials, examinations arranged by the employer, and the medical evidence and any determination concerning maximum medical cure.
Vessels sail, crews disperse, and electronic data is overwritten. The worker’s own calendar, messages, and photographs frequently survive longest, and the firm asks for them first.
Tugs, tows, and supply vessels on the Gulf Coast
Much of Houston’s maritime work happens inside the Coast Guard’s Vessel Traffic Service area for Houston and Galveston, which covers the Houston Ship Channel from the sea buoy to the Turning Basin, the Galveston, Texas City, Bayport, and Barbours Terminal channels, and a stretch of the Intracoastal Waterway. Tug and towboat crews, tankermen on inland barges, pilots’ launches, dredge crews, and the crew and supply boats that serve offshore work all operate within it, and the service’s radio and vessel-tracking records are one more source of evidence when something goes wrong.
Commercial fishing crews are analyzed under the same status test, and a 2022 amendment removed certain aquaculture workers from the Jones Act where state workers’ compensation is available to them. Fishing incidents are reviewed as vessel operations, like any maritime accident; the status questions they raise belong here.
Platforms, harbor work, boats, and deaths belong on other pages
- A worker on a fixed platform, and the question of which framework applies to a rig, a floating facility, or the vessels that serve them, are offshore accident questions.
- Longshore workers, ship repairers, shipbuilders, and harbor construction workers fall under a separate federal system that expressly excludes crew members: Longshore and harbor worker claims.
- Recreational operators and passengers are not seamen; their incidents are boating accidents or jet ski accidents.
- Onshore wellsites, oilfield yards, and shore bases are land-based work that falls under workplace and industrial injuries; shipyards and fabrication yards on navigable water raise the Longshore questions in the bullet above.
- When a seaman dies, the statute allows the personal representative to bring the action, and the family and estate questions, along with the specialized rules that can apply to a death at sea, are part of a wrongful death claim.
Talking with the firm about a crew injury
The useful starting facts are the vessel’s name and owner, the employer’s name, the company that directed the work, the worker’s assignments over the past year, what maintenance or medical care the company has provided, and any letters or forms received. A consultation begins with those facts, and the firm identifies which records establish the vessel connection and which companies owe which of the three duties.
