USL&H Coverage for Florida Marine Artisan Contractors
A marine mechanic carries Florida workers’ compensation, has done for years, and has never had a problem. Then a technician is injured working on a customer’s boat in a slip, and the claim turns out to fall under federal law instead of state law.
That is not a rare edge case. It is the most common serious coverage gap in the marine artisan trades, and it comes from a simple fact: the same employee doing the same job can be under two different compensation systems depending on where they are standing.
The Law Behind It
The Longshore and Harbor Workers’ Compensation Act is a federal workers’ compensation system covering maritime employees who are not crew members of a vessel. It has existed since 1927 and it operates independently of state law.
Coverage turns on two questions, and both have to be answered yes.
Situs — where the work happens. The Act reaches injuries occurring on navigable waters, and also on adjoining areas customarily used for building, repairing, dismantling, loading, or unloading vessels. That includes piers, wharves, dry docks, marine railways, terminals, and the adjoining yard where a hauled vessel sits.
Status — what the work is. The employee must be engaged in maritime employment. Ship repairers, shipbuilders, and harbor workers are named in the statute.
A technician rebuilding an engine in your shop three miles inland generally fails the situs test. The same technician doing the same work aboard the boat in a slip, or on a hull in the yard next to the travel lift, generally meets it.
The Recreational Vessel Exception Is Narrower Than It Sounds
Many Florida marine artisans work almost entirely on recreational boats, and there is an exception in the statute that appears to cover them.
The Act excludes individuals employed to build recreational vessels under a specified length, to repair recreational vessels, or to dismantle part of a recreational vessel in connection with repair — but only where the employee is covered by a state workers’ compensation law.
Three things limit how much comfort that provides.
It applies to recreational vessels. A charter boat, a commercial fishing vessel, a crew boat, a dive operation’s vessel, or a boat in commercial service is not recreational. If your business touches any commercial vessels — and in Florida many do without thinking about it — the exception does not reach that work.
It applies to specified activities. Building, repairing, and dismantling in connection with repair. Work that falls outside those descriptions may not be covered by the exception.
Whether it applies is determined after the injury. The exception is a legal question resolved by the facts of the specific claim, sometimes by a judge. A business relying on it is betting that every vessel it touches and every task it performs stays inside the boundary.
For a shop working exclusively on recreational boats, the exception may well apply. For most marine artisan businesses in Florida, the mix of work makes it an assumption rather than a plan.
State Coverage Does Not Substitute
This is the part that surprises people.
A Florida workers’ compensation policy covers claims under Florida’s system. Where the federal Act applies, the obligation is federal, and the state policy does not satisfy it on its own.
The fix is straightforward and inexpensive relative to the exposure: a USL&H endorsement added to the workers’ compensation policy extends it to cover federal claims. Some carriers write it readily; others have limited appetite for marine exposure, which is itself a reason to know where your business sits before renewal.
Federal benefits are generally more generous than Florida’s, which is part of why the difference matters at claim time.
What Happens Without It
An employer who should be covered under the Act and is not faces consequences beyond paying the claim.
The employer may lose the protections that workers’ compensation normally provides — meaning the injured employee may be able to sue the business directly rather than being limited to a benefits claim. Statutory penalties can apply, and in cases of willful failure to secure coverage the consequences escalate further.
The exclusive remedy protection that makes workers’ compensation valuable to an employer only exists where the correct coverage is in place.
The Gap Between the Two Systems
There is a category of maritime injury that falls outside both state compensation and the federal Act, and that is where maritime employers liability comes in.
MEL responds to employee injury claims that neither system covers, and it is commonly written alongside a USL&H endorsement rather than instead of it. For a business whose employees work on the water, aboard vessels, and in yards, having both closes the space between them.
There is also a zone of concurrent jurisdiction where an injured worker may have a choice of which system to proceed under. That is an argument you would rather have covered from both directions.
Sea Trials Raise the Jones Act
If an employee goes underway aboard a vessel — during commissioning, a sea trial, a delivery, or a test run after an engine job — a different question opens.
The Jones Act covers seamen, meaning crew members of a vessel in navigation with a substantial connection to it. A yard worker who occasionally rides along is not usually a seaman, but the analysis is fact-specific and it is litigated because the stakes are high: a Jones Act claim is a negligence lawsuit against the employer, not a benefits claim with defined limits.
Businesses whose technicians regularly go underway should raise this specifically rather than assume it away.
Marinas Are Increasingly Asking
Beyond the legal obligation, marina and boatyard access requirements have tightened.
Facilities that require shiprepairer’s liability endorsements before granting access are also asking about workers’ compensation, and some specifically require evidence of USL&H coverage. A contractor whose certificate shows Florida coverage only may find themselves declined at the gate.
That makes this a business development question as well as a coverage one. Our guide to what marinas look for before allowing contractors to work onsite covers the broader access requirements.
The Conversation to Have With Your Agent
The useful information is factual, not legal. Four things describe your exposure:
Where your employees physically work. In a shop, on a hauled vessel in a yard, on a boat in a slip, on a dock, or underway. Give the actual breakdown rather than the primary one.
What kinds of vessels you service. Recreational only, or does the mix include charter boats, commercial fishing vessels, dive operations, or anything in commercial service.
Whether anyone goes underway. Sea trials, deliveries, test runs, commissioning.
What your marina and yard agreements require. Some specify coverages by name.
From those four answers, an agent working in this market can tell you whether a USL&H endorsement belongs on your policy, whether maritime employers liability should sit alongside it, and where your current program stops.
