Jones Act Coverage

Seamen — the master and crew who work aboard a vessel in navigation — are excluded from both state workers' compensation and the federal USL&H system. Instead, the Merchant Marine Act of 1920, known as the Jones Act, gives an injured seaman the right to sue the employer for negligence and recover damages, much like a landbound employee could if workers' comp did not exist. That makes crew injuries a fault-based liability exposure, not a no-fault benefit obligation — which is why it requires its own coverage rather than a standard comp policy.

Jones Act coverage is typically written as part of a marine employers liability or protection-and-indemnity (P&I) program and responds to three overlapping seaman remedies: Jones Act negligence claims, unseaworthiness claims (a strict-liability doctrine that the vessel or its equipment was not reasonably fit), and maintenance and cure (the shipowner's ancient duty to pay a sick or injured seaman's living expenses and medical care until maximum recovery). Because these remedies allow full tort damages — including pain and suffering — a single serious crew injury can dwarf what a comp claim would cost, so limits and defense provisions deserve close attention.

A practical nuance is who counts as a seaman. The test hinges on whether the worker has a substantial connection to a vessel in navigation, and misclassifying a dockworker as crew (or vice versa) can leave a gap between Jones Act and USL&H coverage. Employers with any floating operation — charter boats, tugs, workboats, commercial fishing, dive vessels — should coordinate Jones Act, ocean marine, and hull cover so every worker falls under exactly one system. Buyers should confirm the policy covers maintenance and cure and unseaworthiness, not just Jones Act negligence, since plaintiffs routinely plead all three.
