The cruise line called him a longshoreman to shrink its duties. The seaworthiness warranty said otherwise.
An injured marine engineer fell from a defective shipboard ladder — no handrail, no non-skid, wet rungs. We showed that an absolute, non-delegable duty the cruise line tried to argue away still reached him.
A marine engineer aboard a cruise ship, doing the ship's own work.
Our client was a marine engineer. A ship-repair contractor had assigned him to service a large cruise vessel — replacing the rotating filter wheels that keep the ship's air-conditioning system running, work that takes hours per unit and has to be done on a recurring schedule to keep the vessel functioning. He was, in every practical sense, doing the ship's own work.
He was not the cruise line's direct employee. He worked for the repair contractor, and his workers'-compensation coverage came through state law — not the federal Longshore Act. That detail, which the cruise line tried to turn against him, turned out to be the key that unlocked an older and more powerful duty.
To reach the platform where the filter units sat, he had to climb a fixed vertical ladder. The ladder is where this case begins.
What Sieracki is, and why a cruise line fights so hard to escape it.
Maritime law gives vessel owners an unusually demanding obligation: the warranty of seaworthiness. The vessel, its equipment, and its appurtenances must be reasonably fit for their intended use. Crucially, that duty does not depend on negligence — a shipowner can be liable for an unseaworthy condition it neither created nor knew about.
The warranty is absolute, non-delegable, and survives outside LHWCA coverage.
In Sieracki, the Supreme Court extended the seaworthiness warranty beyond a vessel's own crew to other workers "doing a seaman's work and incurring a seaman's hazards." The 1972 amendments to the Longshore Act, through § 905(b), removed that warranty — but only for workers covered by the LHWCA, who were left with a narrower negligence claim.
The Fifth Circuit has held the warranty still lives for a worker who is not eligible for LHWCA yet is doing a seaman's work — contributing to the function of the ship or the accomplishment of its mission. That is the gap a cruise line tries to paper over by simply calling the worker a "longshoreman."
If the worker really were an LHWCA longshoreman, the cruise line would face only the narrow vessel-negligence duties of Scindia. If he were not, the absolute seaworthiness warranty was back in play. The entire summary-judgment fight ran through that fork.
The ladder.
The ladder our client had to use was a fixed vertical steel ladder with no handrails. Its rungs were narrow, turned upward in a diamond profile, and carried no non-skid surface. On the day of the injury there was moisture on the deck and watery footprints in the area; the rungs were wet.
A retained master mariner with more than fifty years in the industry was blunt about the ladder: in his career he had never seen rungs built like these, turned up in a diamond with no flat surface and no non-skid, on a ladder with no handrail. A proper ladder, he said, has flat rungs, a non-skid surface, and a handrail — and he was surprised the vessel's safety personnel had not flagged and replaced it, especially when other ladders aboard the ship did have handrails.
Four arguments for "no duty" — and why each missed.
Five moves that kept both duties in the case.
Disqualified the "longshoreman" label
We established with declarations and records that our client was never paid LHWCA benefits, was never classified as a longshoreman by his employer or its carrier, and was injured in foreign waters — closing the door on § 905(b).
Proved he was doing a seaman's work
Deposition testimony showed his crew kept the ship's air-conditioning system functioning — recurring, hours-long maintenance essential to the vessel's operation. That places him squarely inside the Aparicio / Cormier line and revives Sieracki.
Invoked the absolute, non-delegable warranty
Because seaworthiness does not depend on fault, blame, or notice, the cruise line could not escape by claiming it neither created nor knew of the condition. A ladder unfit for its intended use is unseaworthy, full stop.
Layered the contractual safe-workplace duty
Independent of Sieracki, we pointed to the cruise line's written promise of a safe working environment, reinforced by crew testimony that the line's safety officers were responsible for spotting and fixing hazards, and by international shipboard-safety standards requiring prompt cleanup of spills.
Defused "open and obvious" and the "substance" red herring
We tied liability to the active-control duty and the ladder's defects rather than a duty to warn — neutralizing the open-and-obvious defense and making the unidentified substance legally beside the point.
What a safe ladder requires — and what was bolted to the bulkhead.
- Flat rungs sized for a secure foothold
- A non-skid surface on every rung
- A handrail to catch and stabilize a climber
- Railings on the elevated work platform
- Prompt cleanup of moisture and spills in the work area
- Narrow rungs turned upward in a diamond profile
- No non-skid surface of any kind
- No handrail — though other ladders aboard had them
- No railings on the elevated platform
- Wet rungs and footprints, with no crew attention to the moisture
The cruise line needed to win every argument. It had to answer two.
The strategic point is structural. A defendant moving for summary judgment has to defeat every viable theory; the worker only needs one to survive. By keeping both the seaworthiness warranty and the contractual safe-workplace duty alive — and stripping the open-and-obvious and causation defenses of their reach — the response left the cruise line with no clean path to dismissal.
When a vessel owner reaches for the "longshoreman" label, check whether it actually fits.
Cruise lines and vessel owners routinely argue that a shore-based or contract maritime worker is an LHWCA longshoreman, because that label collapses their exposure to the narrow negligence duties of Scindia and erases the seaworthiness warranty. It is worth testing that assumption every time. A worker who never drew LHWCA benefits, who was hurt in foreign waters, and who was doing the ship's own work may still hold the full, absolute Sieracki warranty.
The second lesson is to never rely on a single duty. The seaworthiness warranty and a contractual safe-workplace duty come from different sources and fail for different reasons; pleaded together, they force the defense to win on every front. And the most quietly powerful fact here was ordinary contract language — a written promise of a "safe working environment" that the vessel owner could not square with a wet, unrailed, non-skid-free ladder.
Map the worker's real status and the owner's real promises before accepting the label the defense hands you. The "longshoreman" who isn't one may be owed far more than the defense wants to admit.
What is the Sieracki seaworthiness warranty?
Under the Supreme Court's 1946 Sieracki decision, a vessel owner owes a duty to provide a seaworthy vessel — equipment and appurtenances reasonably fit for their intended use — not only to its own crew but to certain other workers doing a seaman's work aboard the ship. The duty is absolute and non-delegable, and liability does not depend on negligence, fault, or blame.
Didn't the 1972 LHWCA amendments abolish the seaworthiness warranty for shore-based maritime workers?
Only for workers covered by the Longshore and Harbor Workers' Compensation Act. Section 905(b), added in 1972, limited those covered workers to a negligence claim against the vessel and removed the seaworthiness warranty for them. The Fifth Circuit has held that a worker who is not eligible for LHWCA — but who is still doing a seaman's work — can still rely on the Sieracki warranty.
How does a worker qualify for a Sieracki remedy today?
Two things must be true: the worker is not eligible for LHWCA benefits, and the worker is doing a seaman's work — performing a function that contributes to the ship's function or the accomplishment of its mission. A repair engineer maintaining a vessel's systems, who received only state workers' compensation and was injured in foreign waters, can fit both requirements.
Can a vessel owner avoid liability by calling a hazard "open and obvious"?
Not for these duties. The seaworthiness warranty does not turn on whether a condition was obvious. And where the owner has an active duty to control and maintain the workplace — by contract, law, or custom — liability under that active-control duty is not relieved simply because the hazard was open and obvious.
Can a vessel owner take on a duty to maintain a safe workplace by contract?
Yes. Under Scindia, a vessel owner generally has no duty to supervise a contractor's operations unless that duty is imposed by contract, law, or custom. Where the owner's contract expressly promises the contractor a safe working environment during the work, that promise creates an ongoing duty the owner must actually meet.
Does it matter that the injured worker couldn't identify the exact slippery substance?
Not where the theory is the defective condition of the ladder itself. The argument was not that the owner created the substance, but that a ladder with no non-skid surface and no handrail was not reasonably fit for use — so a slip that a proper ladder would have prevented is traceable to the unseaworthy condition, whatever the substance was.
Case summary
An injured marine engineer fell from a defective shipboard ladder with no handrail, no non-skid, and wet rungs. The cruise line tried to recast him as a longshoreman to shrink its duties, but the seaworthiness warranty, under the Sieracki line of authority, still reached him.
Legal lessons from this case
- The warranty of seaworthiness can extend, in narrow circumstances, to a non-crew worker doing a seaman's work.
- A defective ladder lacking a handrail, non-skid, and dry footing can render a vessel unseaworthy.
- How a worker is labeled does not automatically decide which duties a vessel owes him.
If a vessel owner is calling you a "longshoreman" to limit what it owes you, get it checked.
The line between an LHWCA longshoreman and a maritime worker who still holds the seaworthiness warranty decides how much a vessel owner owes you. If you were injured aboard a cruise ship or other vessel, talk to a maritime trial lawyer before you accept that label.
