Inland Marine Insurance
Inland marine insurance covers business property that is movable, in transit, or used at locations other than the insured's primary premises. Despite its name, inland marine has nothing to do with boats or waterways — it evolved from ocean marine insurance in the early 1900s as a way to cover goods once they left the ship and moved over land. Today, it is the go-to coverage for contractors' tools, mobile equipment, property in transit, and any business assets that travel between job sites.
Why Inland Marine Matters for Independent Agents
Standard commercial property insurance covers business personal property at a scheduled location — the contents of an office, inventory in a warehouse, furniture in a retail store. But the moment that property leaves the premises, coverage becomes limited or nonexistent. A plumber's $40,000 worth of tools stolen from a job site, a caterer's mobile kitchen damaged in a highway accident, or an IT consultant's $15,000 laptop bag left at a client's office — none of these losses are reliably covered under a standard commercial property policy.
This gap affects a huge portion of a commercial agent's book. Contractors, photographers, caterers, event planners, IT consultants, medical equipment suppliers, and fine art dealers all depend on property that moves. When agents fail to identify the inland marine exposure, clients discover the gap at the worst possible time — after a loss — and that's when E&O claims against the agency follow.
Inland marine is also a strong cross-sell line that carries solid commissions. For contractors especially, the conversation flows naturally: you're already writing GL and workers' comp, so asking about tools and equipment on job sites is a logical next step. Carriers like Hartford, Progressive Commercial, and Nationwide offer inland marine as either a standalone policy or a coverage part within a commercial package.
How Inland Marine Works
Inland marine policies fall into several broad categories:
- Contractors' tools and equipment — Covers hand tools, power tools, and small equipment owned by contractors. This is the most commonly written inland marine coverage in a commercial agency. A typical policy covers theft, vandalism, fire, and accidental damage to tools whether they're on a job site, in a truck, or in storage.
- Builders risk — Technically a type of inland marine, builders risk covers buildings under construction. It's often written as a separate policy due to its complexity.
- Motor truck cargo — Covers goods being transported by a trucking company. The trucker has liability for the cargo they haul, and this policy responds when that cargo is damaged or lost in transit.
- Installation floater — Covers materials and equipment being installed at a customer's location. An HVAC contractor installing a $25,000 system at a commercial building needs this coverage until the installation is complete and accepted.
- Electronic data processing (EDP) — Covers computer equipment and related hardware that travels or is used at multiple locations.
Inland marine policies are typically written on an "all-risk" (special form) basis, which provides broader coverage than the named-perils approach used in many commercial property policies. This means the policy covers any cause of loss that isn't specifically excluded, rather than only covering losses from a listed set of perils.
Valuation is a critical underwriting detail agents must get right. Inland marine policies can be written on replacement cost, actual cash value, or agreed value basis. For contractors' tools, replacement cost is almost always the right choice — a five-year-old DeWalt table saw doesn't lose its functional value to the contractor just because it has depreciated on paper.
When submitting an inland marine risk, agents should gather a detailed equipment schedule listing each item, its value, and its age. Carriers like Hartford and Progressive typically require the ACORD 125 as the base application, plus a supplemental inland marine form or the carrier's proprietary equipment schedule. For larger accounts with $250,000 or more in scheduled equipment, underwriters may request maintenance records and storage location details.
Deductibles on inland marine policies are generally lower than commercial property — often $500 to $2,500 — because the individual items being covered are discrete and their values are well-documented.
Frequently Asked Questions
What is inland marine insurance? Inland marine insurance covers movable property, goods in transit, and specialized equipment that standard commercial property policies exclude or inadequately protect. Despite its name, it has nothing to do with water — it evolved from ocean marine coverage to protect property once it leaves a ship and moves over land. Today, it covers contractors' tools, mobile equipment, goods in transit, installation floaters, and any business property that travels between locations.
Why do contractors need inland marine coverage? Standard commercial property policies cover business personal property at a scheduled premises — not property in transit or at off-site locations. A contractor's $40,000 in tools at a job site, in a truck, or in a remote storage unit is not reliably covered under a standard property policy. Inland marine fills this gap with specific tools-and-equipment coverage that follows the property wherever it goes. Failing to identify this exposure is one of the most common inland marine-related E&O claims in commercial agencies.
What types of businesses most commonly need inland marine coverage? Contractors (tools and equipment at job sites), trucking companies (motor truck cargo), caterers (mobile kitchen equipment), photographers and videographers (camera equipment), IT consultants (laptops and peripherals at client sites), HVAC contractors (installation floaters for systems being installed), and fine art dealers (scheduled articles) all have significant inland marine exposures. Any business whose valuable property moves between locations should be evaluated for this coverage.
How does inland marine differ from commercial property insurance? Commercial property covers assets at a fixed, scheduled location. Inland marine covers assets that move — in transit, at temporary locations, or being used at a client's premises. For a contractor, the equipment in the office is covered by commercial property; the equipment in the truck and at job sites is covered by inland marine. Both coverages are necessary for a complete commercial insurance program for any mobile-asset business.
