Marine Liability Insurance in Florida for Waterfront Work

Coverage for Projects On or Near Water

When Construction Meets Marine Risk

Marine construction brings a different set of exposures than land-based work. Jobs along the St. Johns River, the Intracoastal Waterway, Tampa Bay, or South Florida canals often involve barges, docks, marinas, seawalls, and shoreline equipment. Marine liability insurance helps cover third-party injury, property damage, and legal costs tied to those operations.


GM Insurance Underwriters arranges marine liability coverage for Florida contractors who work over water, near shorelines, or in tidal zones. We look closely at the job type, equipment used, and contract language so the policy lines up with how your crews actually work.

What Marine Liability Can Cover

Protection Built for Waterfront Exposures

Marine liability insurance is often paired with your broader construction program and can include coverage for:

Liability from marine operations such as dock, pier, or seawall work

Damage to third-party property in or near the water

Injuries to non-employees connected to marine activity

Certain pollution incidents tied to marine work, when endorsed

Coverage extensions for vessels or barges used on a job

Liability arising from underwater work or use of diving contractors

Because standard general liability policies may exclude or limit marine operations, this coverage fills an important gap for contractors who regularly work in waterfront environments.

Florida-specific Marine Considerations

Coastal Jobs, Tidal Changes, and Storm Exposure

Florida marine projects are affected by shifting tides, heavy boat traffic, and hurricane season. A barge bumping a neighboring vessel, equipment drifting during a storm, or debris entering a channel can turn into a major claim if coverage is not properly structured.


We help clients working in areas like Mayport, Ponte Vedra, St. Augustine, Clearwater, St. Pete, and Miami Beach plan for these realities with limits and endorsements that make sense for the job.

Questions Florida Marine Sontractors Ask

  • Do I need marine liability if I already have general liability?

    If your operations involve work on, over, or next to water, many carriers require marine coverage because general liability may exclude those risks.

  • Does marine liability cover pollution?

    Some policies can include limited pollution coverage related to marine operations. For broader environmental protection, we often add a dedicated contractors pollution policy.

  • How are marine policies priced?

    Pricing depends on job type, locations, equipment, claims history, and vessel exposure. We’ll review your scope and shop carriers that write Florida marine risks.
