Jones Act vs USL&H vs State Comp: Three Laws, One Injured Worker, One Very Expensive Gap

By Winfield Lee, Licensed Independent Insurance Agent · Serving Georgia & the Southeast · Updated 2026

Short answer

When a marine worker gets hurt, one of three legal regimes governs what you owe — and you usually don't get to pick which one:

• State workers' compensation — the ordinary no-fault system for land-based employees.
• USL&H (the Longshore and Harbor Workers' Compensation Act) — a federal no-fault system for maritime employees working on navigable waters and on adjoining piers, wharves, terminals and marine railways. Benefits generally run higher than state scales, and it takes a specific endorsement on your comp policy.
• The Jones Act — not a benefits system at all. A seaman, meaning a crew member with a substantial connection to a vessel in navigation, can sue the employer for negligence, typically in front of a jury, alongside maintenance and cure and unseaworthiness claims.

A standard comp policy answers the first one. It generally does not answer the other two without being endorsed — and status is very often decided after the injury, by a court.

Why this page exists

The coastal strip from Savannah to Brunswick to Charleston to Jacksonville runs a real marine economy: tug and barge operators, marine transport and bunkering, dredging and marine construction, ship repair and shipyard subcontractors, stevedoring and terminal labor, commercial fishing and shrimping fleets, charter and tour boats, marinas and boatyards, pile driving and dock builders, and shoreside contractors whose crews reach the job by boat.

A great many of those companies are small, owner-run, and carrying a workers' comp policy that says Georgia or South Carolina on the information page and nothing else. That policy is correct right up until the day it isn't.

The three regimes side by side

Application depends on the facts and on federal and state law, both of which are amended and both of which develop through case law. Nothing here is legal advice — confirm status questions with qualified maritime counsel.

Seaman status: the question nobody can answer in advance

Seaman status is a legal determination, not a job title. Broadly, courts have looked at whether the worker's duties contribute to the function of a vessel or the accomplishment of its mission, and whether the worker's connection to a vessel — or to an identifiable fleet — is substantial in both duration and nature.

The clean cases are clean. A deckhand on a tug is a seaman. A bookkeeper in the office is not. The problem is everyone in between, and in a small marine company that is most of the roster:

• The dock hand who rides out two days a week.
• The mechanic who goes along on the run to keep the engine turning.
• The crane operator working off a spud barge.
• The dredge crew.
• The diver, and the tender on the boat.
• The supervisor who splits time between the yard and the vessel.

Any of those can land on either side of the line depending on the actual, provable pattern of the work — and the determination generally comes after a serious injury, in litigation, with the worker's lawyer arguing hard for the Jones Act because the recovery is larger.

Maintenance and cure, and why one injury becomes three claims

Maintenance and cure is an old general maritime obligation owed to an injured or ill seaman, and it is largely independent of fault. Maintenance is generally a daily allowance approximating room and board ashore during recovery; cure is generally reasonable medical expense until maximum medical improvement. It is not administered by a state agency against a fee schedule — it is enforced through the courts, and an unreasonable failure to pay it can expose the employer to additional damages.

It also runs alongside the other theories rather than instead of them. A single injury to a crew member can generate, at once:

1. A maintenance and cure obligation, largely regardless of fault.
2. A Jones Act negligence claim against the employer.
3. An unseaworthiness claim against the vessel — alleging the vessel or its equipment or crew were not reasonably fit for their intended purpose.

Anyone whose mental model of an injury claim is "file it with comp and the adjuster handles it" should sit with that list for a minute. These doctrines are governed by federal maritime law and case law which continue to develop; confirm specifics with qualified counsel.

What your comp policy actually covers — and what it doesn't

This is where uninsured marine claims are born. A standard workers' compensation and employers liability policy covers benefits under the workers' comp law of the states listed on the information page. Beyond that:

• USL&H coverage is generally added by a specific Longshore coverage endorsement, at additional premium and on a different rate basis for the subject payroll — because Longshore benefits are generally higher than state scales.
• Jones Act exposure is a negligence suit, not a benefits claim. It is generally reached through the employers liability part only if a maritime coverage endorsement is added, or otherwise through protection and indemnity or a maritime employers liability policy.

Endorsement availability, wording and rating vary by carrier, state and form edition. Read the policy as issued, not the summary. If you want the general mechanics of how a comp premium and audit work before you get into the maritime layer, our Georgia small business comp and experience mod pages cover it.

Maritime employers liability (MEL): who actually needs it

MEL responds to Jones Act negligence, maintenance and cure, and unseaworthiness claims by crew, where those exposures are not already picked up under a protection and indemnity policy. It exists mostly for one situation: your people are aboard a vessel you don't own. Common candidates:

• Employees working aboard vessels owned or chartered by a customer.
• Contractors whose crews ride to the job site by boat — dock builders, pile drivers, utility and civil contractors working over water.
• Marine construction and dredging operations.
• Diving operations.
• Any employer with borderline workers who might be found to be seamen.

If you own the vessels and employ the crew, crew exposure is frequently addressed inside P&I instead, in which case MEL may be redundant — or may fill one defined gap. This is a coordination exercise across the comp policy, the P&I and any MEL, not a checkbox. The wrong outcome isn't usually "no coverage anywhere"; it's two policies each pointing at the other.

The vessel side: hull, P&I, and the tow

For a working tug, barge, crew boat or marine transport operation, the employer coverages above are only half the program. The vessel half generally includes:

• Hull and machinery — physical damage to the vessel, usually with a meaningful deductible and with navigational limits or trading warranties that define where she may go. Operating outside the warranty is a coverage problem, not a paperwork problem.
• Protection and indemnity (P&I) — the owner's liability out of vessel operations: commonly crew injury, third-party injury, damage to other property, and certain removal and legal expense, subject to the form.
• Towers liability / tow legal liability — liability for damage to the tow itself, which a standard liability form may treat as property in your care and restrict accordingly. For a tug and barge operator this is not optional reading.
• Collision liability and wreck and debris removal.
• Pollution liability and evidence of financial responsibility where required by law — a statutory obligation for many operators, and separate from any broader contractors pollution coverage. Requirements are set by federal and state authority and are amended; confirm with the applicable authorities.
• Charterers legal liability where you charter vessels in, and cargo legal liability where you carry goods for others.
• Shoreside: coastal property on offices, docks and shops — with named storm deductibles read carefully — plus commercial auto, equipment breakdown, business interruption and excess or bumbershoot limits over the whole structure.

Much of this places in the surplus lines market rather than with a standard carrier, and several of these forms are claims-made — which makes continuity between renewals worth real attention.

What underwriters actually look at

Marine underwriting looks less like a rate table and more like a file review. The recurring variables:

• Vessel age, value, type and condition — and the survey record, including whether prior recommendations were closed out.
• Trading area: inland, protected coastal, coastwise or offshore. This is the single biggest lever on both hull and liability.
• Tow values and configuration for towing work.
• Crew size, crew payroll, licensing, and the experience of the captains and the operator.
• USCG documentation and inspection status, including the towing vessel inspection regime and any required safety management system where it applies. Requirements are set by federal authority and are amended.
• The contracts being signed — and the indemnity obligations inside them, plus any waiver of subrogation and additional insured requirements. Marine contracts frequently contain knock-for-knock and hold-harmless wording that reallocates the whole risk picture.
• Named windstorm and layup exposure for vessels moored in the hurricane belt.
• Loss record, with a plain narrative on any serious injury or casualty and what changed after it.

The gaps that show up most often

1. No USL&H endorsement on the comp policy at a company with shoreside maritime workers.
2. No Jones Act answer at all — neither a maritime endorsement to employers liability, nor P&I crew coverage, nor MEL.
3. Crew payroll reported as land classifications, which produces both an audit liability and a bad conversation about how the operation was described.
4. No towers liability at an operator whose whole business is moving somebody else's barge.
5. Trading warranty breaches — running outside navigational limits because a customer asked.
6. Contract labor and 1099 crew assumed to be somebody else's problem. The 1099 question and the staffing arrangement question are sharper here than anywhere on land, because a borrowed servant aboard your vessel can still be your Jones Act exposure.
7. An umbrella or bumbershoot that doesn't schedule the marine underliers — a common and expensive mismatch.
8. No EPLI or cyber, on the theory that a boat company doesn't need them. Payroll disputes and fraudulent wire instructions do not care that you work on water.

What a strong marine submission contains

1. Vessel schedule: name, official number, year, type, length, horsepower, value, and current survey with recommendations closed.
2. Trading area and routes actually run — not the ones on the brochure.
3. Towing operations: typical and maximum tow values, configuration, and whether you tow for others.
4. Full payroll split: crew aboard, shoreside maritime, clerical — with the basis for each classification.
5. Crew roster with licenses, endorsements and years of experience; captain resumes.
6. USCG documentation and inspection status, and your safety management system documentation.
7. Contracts with your three largest customers, with the indemnity and insurance articles flagged.
8. Whether employees ever work aboard vessels you do not own, and under whose control.
9. Contract labor and staffing arrangements, with certificates.
10. Shoreside schedule: offices, docks, shops, equipment, with coastal and named-storm exposure noted.
11. Pollution financial-responsibility evidence currently held.
12. Five years of loss runs, with a narrative on every serious injury and casualty and what changed after it.

Where Bettr Coverage fits

Bettr Coverage is an independent commercial insurance agency serving Georgia and the wider Southeast, and marine employer risk is a place where the single most valuable thing an agent does is read three policies against each other. On a marine review we look for whether a Longshore endorsement exists at all, whether anything on the program answers a Jones Act suit, whether crew payroll is being reported where the carrier thinks it is, whether towers liability covers the barge you tow every week, and whether the umbrella actually schedules the marine underliers. One agency, one relationship, all of it read together — and a local number to call when a deckhand gets hurt at two in the morning.

For general information only. Not legal advice and not a quote or contract of insurance. Seaman status, coverage under the Jones Act, the Longshore and Harbor Workers' Compensation Act and general maritime doctrines including maintenance and cure and unseaworthiness are governed by federal statute and case law which are amended and which continue to develop; application depends on the specific facts and should be confirmed with qualified maritime counsel. Policy forms, endorsements, sublimits and exclusions vary by carrier and form edition — Longshore and maritime coverage endorsements to workers' compensation and employers liability, protection and indemnity crew provisions, maritime employers liability terms, hull navigational limits and trading warranties, towers and tow legal liability, collision and wreck removal provisions, charterers and cargo legal liability, claims-made retroactive dates, named storm deductibles, and umbrella or bumbershoot scheduling of underlying marine policies must all be read as actually issued. Workers' compensation classifications, rates, experience rating and payroll rules are set by NCCI or the applicable state rating authority and by carrier filings, and are amended; class assignment is determined by the carrier and auditor on the facts of the operation. Vessel documentation, inspection, manning, safety management and pollution financial-responsibility requirements are set by federal, state and local authority and are amended; confirm your obligations with the applicable authorities. Coverage subject to policy terms, conditions, exclusions and carrier appetite.
