Common Definitions of Maritime Coverage’s

The Longshore and Harbor Workers’ Compensation Act and its extensions, provide
medical benefits, compensation for lost wages, and rehabilitation services to employees
who are injured during the course of employment or contract an occupational disease
related to employment. Survivor benefits also are provided if the work-related injury
causes the employee’s death. Situs – having “situs” means the work is on or adjacent to
navigable waters.
Longshore – literally means “along the shore”. Refers to maritime employment, other than
work as a seaman. Includes work building and repairing ships, loading and unloading
ships, construction or repair of structures to enable waterborne commerce, and other work
on or near navigable waters in support of waterborne commerce.
Status – having “status” means the work is generally “maritime” in character, unless
specifically excluded in the Longshore and Harbor Workers Act. Work as an employee of
a political subdivision is also excluded.
USL&H – means the United States Longshore and Harbor Workers Compensation Act, a
federal law in many respects like any state’s Workers’ Compensation law, except that it
only applies to employers and employees engaged in maritime work.
Admiralty – refers to the common law of the sea, enforced by the federal Courts. Seamen
have certain rights and remedies against their employers under Admiralty Law, if injured
on the job or during a voyage.
Jones Act – a federal law that extended the Federal Employer’s Liability Act (FELA) to
give injured seamen the right to sue their employer in federal Admiralty courts for their
work-related injuries.
Maritime – generally means “pertaining to the sea”. In connection with the USL&H Act,
“maritime” work means work that meets the “situs” and “status” tests, including building
and repairing ships, loading and unloading ships, construction or repair of structures that
enable waterborne commerce, and other work on or near navigable waters in support of
waterborne commerce. Also references work in connection with the Jones Act.

activities, typically launching, docking, storing, fueling and incidental servicing of boats.


MEL – “Marine Employers Liability” coverage, often provided under a P & I policy or
monoline, to protect the employer against his liabilities under the Jones Act and Admiralty
law for injury to his employed seamen. Known as “Maritime Coverage” when provided as

Seaman – a maritime employee who works on a “vessel”, contributes to the functioning of
the “vessel” and the accomplishment of its mission, and has a connection to the vessel or a

a “seaman”.
