Inland marine insurance: what it covers and who needs it

Despite the name, inland marine has nothing to do with water. It is a broad category of commercial insurance that covers property that moves — tools, equipment, goods in transit, and property not permanently attached to a building. It is one of the most commonly missed coverages on commercial accounts, particularly for contractors and trades.

Why commercial property doesn't cover equipment in the field

Commercial property insurance covers property at a scheduled location — the business's building, office, or warehouse. Equipment that leaves the premises — tools in a truck, a generator at a job site, a laptop in transit — is generally not covered by standard commercial property.

This gap surprises many business owners. A contractor who has $150,000 in tools and equipment at various job sites assumes it's covered somewhere. Often, it isn't — unless they specifically purchased inland marine coverage.

What inland marine covers

Inland marine is a flexible coverage that includes several major subtypes:

• Contractors equipment floater — covers tools and equipment owned or leased by the contractor, wherever they are. Covers theft, damage, breakdown (depending on form), and loss. This is the most common inland marine need for contractor accounts.
• Builders risk — covers a building under construction, including materials on site or in transit. Required on most construction projects and typically purchased by the owner or GC for the project period.
• Installation floater — covers materials and equipment from the point of purchase until installation is complete. Fills the gap between the contractor's property coverage and the builders risk policy.
• Commercial articles floater — covers specific high-value items (cameras, musical instruments, medical equipment) on a scheduled basis.
• Cargo insurance — covers goods in transit for businesses that ship products regularly.
• Electronic data processing (EDP) equipment — covers computers, servers, and data — often broader than standard property coverage for these items.

Who needs inland marine

Any business that takes valuable property off-premises regularly. The most common candidates:

• General contractors and specialty trades with tools and equipment at job sites
• Landscapers with mowers, trailers, and equipment at client properties
• Photographers and videographers with cameras and equipment
• Distributors and truckers moving goods in transit
• Technology companies with servers and expensive electronics
• Healthcare providers with portable diagnostic equipment

How inland marine is underwritten

Contractors equipment floaters — the most common form — are typically written on a scheduled or blanket basis. Scheduled coverage lists each piece of equipment individually with a stated value. Blanket coverage covers all tools and equipment up to a total limit, without a per-item schedule.

Underwriters want to know: total value of equipment, where it's used (local vs. multiple states), how it's stored (locked vehicles, secured job sites), and any prior theft or equipment losses. Most policies exclude mechanical breakdown unless specifically endorsed.

Inland marine as a cross-sell opportunity

For contractor and trade accounts, inland marine is often an easy cross-sell that clients genuinely need and don't realize they're missing. The conversation starts with a simple question during the intake process: "What is the total value of your tools and equipment? And where do they typically go — are they at job sites, in vehicles, or back at the shop each night?"

That question identifies the exposure. A contractor who answers "$80,000 in tools and equipment" and "we leave most of it at the site overnight during long projects" has just described a significant uninsured exposure. Building this question into your commercial intake process ensures you never miss the opportunity.
