Inland marine: scheduled vs blanket coverage

Inland marine insurance exists to protect property that moves, changes locations, or doesn’t fit neatly under standard property policies. Tools, equipment, mobile machinery, cameras, fine art, and contractor gear often live in this category.

The most common—and most expensive—mistake with inland marine isn’t forgetting coverage. It’s choosing the wrong structure. Understanding the difference between scheduled and blanket coverage is critical to avoiding hidden per-item caps and underpaid claims.

Foundations

What inland marine is designed to solve

Inland marine fills the gaps left by standard property insurance when assets are mobile, temporary, or used away from a fixed location.

  • Mobile property: tools, equipment, cameras, electronics, and machinery that travel.
  • Job-site exposure: property at temporary locations or in transit.
  • Special valuation needs: items where depreciation or sublimits create unacceptable gaps.
Inland marine isn’t about geography—it’s about mobility, use, and exposure.
Coverage structures

Scheduled vs blanket: the core distinction

The difference between scheduled and blanket coverage isn’t cosmetic—it determines how claims are paid.

  • Scheduled coverage: items are individually listed with specific values.
  • Blanket coverage: groups of items are covered under a shared limit.

Both structures are valid. Problems arise when the structure doesn’t match how the equipment is actually used.

The right structure depends on whether your risk is item-specific or portfolio-wide.
Scheduled coverage

What scheduled inland marine is built for

Scheduled coverage is precision-based. Each item carries its own value and limit.

  • Item-by-item limits: Each scheduled piece is insured up to its listed value.
    If a $45,000 excavator is scheduled at $45,000, that is the maximum available for that item.
  • Clear valuation: Ideal for high-value, identifiable assets with stable inventories.
  • Cleaner claims: Less debate about what was covered and for how much.

Best fit for scheduled coverage

  • Heavy equipment and large machinery
  • High-value cameras or specialty tools
  • Assets with serial numbers and stable ownership
Scheduled coverage trades flexibility for certainty.
Blanket coverage

What blanket inland marine is designed to solve

Blanket coverage focuses on total exposure rather than individual items.

  • Shared limits: Multiple items draw from one overall limit.
    Losses are paid up to the blanket limit, subject to any per-item caps in the policy.
  • Operational flexibility: Items can be added, removed, or swapped without constant policy updates.
  • Inventory efficiency: Reduces administrative burden for businesses with frequently changing gear.

Best fit for blanket coverage

  • Tool fleets with frequent turnover
  • Contractors with many mid-value items
  • Businesses where loss scenarios affect multiple items at once
Blanket coverage trades precision for flexibility—if the limits are built correctly.
The hidden risk

The per-item cap problem

The most common inland marine claim shortfall comes from overlooked per-item caps.

  • Unstated assumptions: Blanket coverage does not automatically mean “unlimited per item.”
    Many policies impose sublimits like $10,000 or $25,000 per item unless scheduled.
  • Loss concentration: Theft from a trailer or job site often involves multiple items at once.
  • Surprise outcomes: A $60,000 loss can become a $25,000 payment if caps weren’t addressed.
Blanket limits don’t help if individual items are capped below their real value.
Design strategy

How to choose the right structure

The right inland marine design often blends both approaches.

  • Schedule the outliers: Individually list high-value items that exceed common per-item caps.
  • Blanket the rest: Use blanket limits for the bulk of tools and mid-range equipment.
  • Model worst-case losses: Theft, fire, or rollover scenarios often involve multiple items at once.
  • Confirm valuation: Replacement cost vs ACV matters more for equipment than many owners realize.
Good inland marine design is about loss scenarios, not just totals.
Execution

Questions to ask before binding coverage

These questions surface structure problems before they show up in a claim.

  • What is the per-item cap? Is it stated in the form or endorsement?
  • What loss scenarios were assumed? Single-item loss vs multi-item theft.
  • How often does inventory change? Weekly turnover favors blanket structures.
  • What documentation is required? Receipts, serial numbers, or inventories.
  • How are new items treated? Automatic coverage vs endorsement required.
The best inland marine policies are boring—because nothing unexpected happens after the loss.
Quick FAQs

Common questions

Is blanket coverage cheaper than scheduled?
Sometimes, but not always. Blanket policies can be cost-effective for large inventories, but pricing depends on limits, per-item caps, and loss history.

Can I convert from blanket to scheduled later?
Yes. As equipment values grow or inventories stabilize, scheduling high-value items is common.

Does inland marine cover rented or borrowed equipment?
Not automatically. Coverage depends on policy wording and may require specific endorsements.

Bottom line

Structure matters more than the limit

Inland marine losses rarely fail because coverage was missing—they fail because the structure didn’t match the risk. Use scheduled coverage for high-value outliers, blanket coverage for flexible inventories, and always confirm per-item caps before assuming the limit will respond the way you expect.
