The oldest promise in maritime law
It usually starts with something small. A mooring line that should have been retired two voyages ago. A winch brake that slips a quarter inch under load. A deck light that’s been out for a week because the part is “on order.” Nobody writes those up. Then one night the line parts, and a man’s life changes in the time it takes the bitter end to travel across the deck.
Here is what the man on that deck could not do. He could not inspect the wire rope before he signed on. He could not audit the maintenance records, count the crew against the watch schedule, or test the brake before the vessel left the dock. He took the vessel exactly as the company handed it to him.
So the law makes the company a promise on his behalf: the vessel, its gear, and its crew will be reasonably fit for the work. That promise is called the warranty of seaworthiness. It is absolute, it cannot be delegated to a contractor or a manning agency, and it is older than the Jones Act itself. The promise does not ask whether the owner tried. It asks whether the vessel was fit. If the answer is no, and that unfitness played a substantial part in your injury, the owner is responsible — full stop.
What makes a vessel unseaworthy?
Anything about the vessel, its equipment, or its crew that is not reasonably fit for its intended use. The question is the condition of the vessel, not the conduct of the owner.
The conditions we see over and over:
- Lines, cables, and rigging that part under normal working loads.
- Winches, cranes, and hoisting gear that slip, jump, or fail.
- Hatch covers, ladders, and gangways that give way.
- Oil, grease, hydraulic fluid, or standing water where crew must walk and work.
- Dead lighting in engine rooms, holds, and working decks.
- Safety equipment that is missing, broken, or the wrong gear for the job.
- Watches stood short-handed because the company ran the vessel lean.
- A crewmember who was never trained for the task — or one the company knew was dangerous.
Two things about this list surprise most injured seamen. First, a temporary condition counts. The Supreme Court settled that decades ago: grease on a rail that had been there an hour can make a vessel unseaworthy just as surely as a cracked hull. Second, the crew itself can make a vessel unseaworthy. A vessel manned by too few sailors, or by one who is untrained or violent, is as unfit as a vessel with a broken crane.
A vessel can be unseaworthy without a single rusted bolt
Fitness for purpose includes the voyage the company ordered. Somali pirates hijacked an American crew — the events behind the film Captain Phillips. We represented the mariners and held the company accountable for sending them into waters it knew were dangerous, and made the industry safer for future mariners.
Brian Beckcom represented nine of the crewmembers taken hostage on the Maersk Alabama in one of the most complex maritime and Jones Act cases in history, and won confidential recoveries for every one of them — a case that changed the safety and security of mariners. When pirates later kidnapped Captain Wren Thomas off the coast of Nigeria, he hired VB Attorneys too.
The lesson for your case: unseaworthiness is not only about rusted cables and slick decks. A vessel sent to do a job it was not equipped to do safely — whatever that job was — was not fit for its purpose.
Do you qualify?
Unseaworthiness claims belong to seamen — workers whose duties contribute to the mission of a vessel (or fleet) in navigation, with a connection that is substantial in duration and nature.
The working rule of thumb federal courts use: if roughly 30% or more of your working time is spent aboard a vessel or an identifiable fleet, you likely satisfy the duration requirement. Tugs, barges, supply boats, drillships, jack-ups and semi-submersibles, tankers, dredges, and commercial fishing vessels all count when they are in navigation — even moored or docked.
If you don’t meet the test — longshoremen and most land-based harbor workers don’t — you are not out of options. Your remedies run through the Longshore and Harbor Workers’ Compensation Act or third-party negligence law instead, and the right path depends on facts we can evaluate from your vessel assignments and time records. Tell us what happened and we’ll give you a straight answer about which law protects you.
Three claims, one case
Most seriously injured seamen have three claims running at the same time, and the value of the case depends on running all three correctly:
| Claim | What you must prove | What it covers |
|---|---|---|
| Unseaworthiness (this page) | An unfit condition of the vessel, equipment, or crew was a substantial factor in your injury. No negligence required. | Full compensatory damages: medical care, lost wages and earning capacity, pain and mental anguish, impairment. |
| Jones Act negligence | Employer negligence played any part in your injury, however slight — the lightest causation standard in American law. | The same categories of compensatory damages, against your employer. |
| Maintenance & cure | You were injured or fell ill in the service of the vessel. No fault required — by anyone. | Daily living expenses and all necessary medical care until maximum medical improvement. |
Notice the difference in what must be proven. The Jones Act asks about the employer’s conduct; unseaworthiness asks about the vessel’s condition. A company can be careful and still put an unfit vessel to sea — and an injured seaman pleads both, because juries answer them separately.
Right now, the evidence is on their vessel
The parted line, the winch that slipped, the maintenance log that shows the brake was written up twice and never fixed — every piece of evidence that decides your case is in the company’s hands, on the company’s vessel, and it starts disappearing the day you’re hurt. Gear gets “repaired.” Lines go over the side. Crews rotate and scatter to other boats and other employers.
That’s why preservation letters go out immediately: vessel and engine-room logs, maintenance and repair records, safety-meeting minutes, manning and watch schedules, the Coast Guard casualty report, and the failed equipment itself — preserved, photographed, and examined before it’s altered. Every day you wait, their version of the story hardens and yours gets harder to prove. One call starts protecting your case today, and it costs you nothing.
