Admiralty law governs injuries, contracts, and disputes arising on navigable waters. It is one of the oldest bodies of law, predating the Constitution, and operates under principles that often surprise lawyers trained in common law. Federal courts have exclusive jurisdiction over most maritime claims, applying substantive law that differs significantly from state tort and contract law.
Sources of Maritime Law
Maritime law draws from multiple sources that interact in complex ways. General maritime law is federal common law developed by courts over centuries. The Jones Act, Longshore and Harbor Workers Compensation Act, Death on the High Seas Act, and various international conventions overlay statutory frameworks. When state law applies, it does so only as surrogate federal law adopted into the maritime framework.
The Constitution grants federal courts admiralty jurisdiction, but the boundaries of that jurisdiction have shifted over time. Navigable waters in interstate or international commerce satisfy the locality test. The connection test asks whether the incident has a substantial relationship to traditional maritime activity.
The Jones Act
The Jones Act provides negligence-based recovery for seamen injured in the course of employment. Unlike workers compensation, which imposes strict liability, the Jones Act requires proof that the employer was negligent. But the causation standard is relaxed. If employer negligence played any part, even the slightest, in causing the injury, liability attaches.
Seaman status is heavily litigated. The two-part test asks whether the worker contributed to the function of a vessel or accomplished its mission, and whether the worker had a connection to a vessel in navigation that was substantial in nature and duration. Courts apply a 30 percent rule of thumb for the duration element, but this is not a rigid requirement.
Seaman status matters because it determines which remedial scheme applies. Seamen get Jones Act negligence claims plus maintenance and cure plus general maritime law unseaworthiness claims. Longshoremen get LHWCA benefits. The distinction between seamen and longshoremen is factual and often contested.
Maintenance and Cure
Maintenance and cure is the maritime equivalent of workers compensation but predates modern workers compensation by centuries. The employer must pay maintenance, a daily living allowance, and cure, meaning medical treatment, until the seaman reaches maximum medical improvement.
The obligation is nearly absolute. Maintenance and cure is not dependent on fault. The seaman need only show the injury or illness occurred or manifested while in service of the vessel. Pre-existing conditions that are aggravated by service qualify.
Willful failure to pay maintenance and cure can trigger punitive damages and attorney fees. This remedy has teeth that workers compensation lacks.
Unseaworthiness
General maritime law imposes on shipowners an absolute duty to provide a seaworthy vessel. Unseaworthiness is not negligence. The owner is liable regardless of fault if an unseaworthy condition caused the injury.
Unseaworthiness extends beyond hull integrity. Defective equipment, inadequate crew, improper training, and unsafe methods of work all constitute unseaworthiness. The standard is whether the vessel and its appurtenances are reasonably fit for their intended use.
This strict liability overlays the Jones Act negligence claim. Seamen can pursue both theories. The unseaworthiness claim often provides easier proof because fault is irrelevant.
Longshore and Harbor Workers Compensation Act
LHWCA provides workers compensation benefits to maritime workers who are not seamen. Longshoremen, harbor workers, ship repairers, and shipbuilders fall within coverage. The Act provides scheduled benefits for injuries and covers medical treatment.
LHWCA is the exclusive remedy against the employer. But third-party claims against vessel owners remain available under general maritime law. The vessel owner’s liability is based on negligence or unseaworthiness, not the strict liability of LHWCA.
Extensions of LHWCA cover defense base workers, outer continental shelf workers, and others. Each extension has its own coverage rules and geographical limitations.
Maritime Liens
Maritime liens are security interests in vessels that arise by operation of law. No filing or recording is required. The lien attaches immediately upon the occurrence of the underlying obligation.
Preferred maritime liens include seamen’s wages, salvage, and general average. Nonpreferred liens include necessaries, contract claims, and tort claims. The priority scheme differs from Article 9 secured transactions.
Enforcement is through in rem action against the vessel. The vessel itself is the defendant. Arrest of the vessel secures the claim and establishes jurisdiction. This in rem remedy is unique to admiralty.
Limitation of Liability
The Limitation of Liability Act allows vessel owners to limit liability to the value of the vessel and pending freight. The limitation applies if the loss occurred without the owner’s privity or knowledge.
Limitation proceedings consolidate all claims against the vessel into a single federal action. Claimants must file claims within the limitation period or be barred. The process protects vessel owners from catastrophic liability but disadvantages claimants who lose venue choices and jury trial rights.
Offshore and Platform Issues
Offshore platforms present classification problems. Fixed platforms attached to the seabed are not vessels, so the Jones Act and general maritime law do not apply. Mobile offshore drilling units may qualify as vessels depending on their operational status.
Workers on fixed platforms generally fall under LHWCA’s Outer Continental Shelf Lands Act extension. But the platform must be connected to natural resource extraction. Workers on platforms used for other purposes may fall through the cracks.
The classification of floating production storage and offloading units, mobile drilling rigs, and other specialized equipment is intensely fact-specific. Small differences in operational status can shift the entire legal framework.
For Service Members
Navy and Coast Guard personnel injured in the line of duty face the Feres Doctrine, which bars tort claims against the federal government for injuries arising out of or in the course of military service. A sailor injured on a Navy vessel cannot sue the government under general maritime law or the Jones Act.
Feres bars not just negligence claims but also unseaworthiness claims against government vessels. The doctrine applies regardless of whether the injury occurred due to equipment failure, command decisions, or the acts of fellow service members.
The injustice is sharpest when civilian mariners are injured in the same incident. A civilian contractor injured alongside a Navy sailor on the same vessel can recover under the Jones Act. The sailor cannot. Same ship, same incident, same injury, different remedies.
Reservists present complexity. Feres applies during active duty but not during civilian employment. A reservist injured while on inactive duty training may or may not fall within Feres depending on the circumstances. The line between military and civilian status is not always clear.
Claims against private parties remain available even when Feres bars claims against the government. If a third-party contractor’s equipment caused the injury, the service member can pursue that claim. Identifying responsible third parties becomes critical when the Feres bar eliminates the government as a defendant.
A military attorney understands where Feres begins and ends, how to identify claims that survive the doctrine, and how to navigate the intersection of military status with maritime remedial schemes.
