5.6 Inland and Ocean Marine: Definitions, Personal Floaters, Commercial Floaters, and Valuable Papers

Key Takeaways

  • Inland marine insures property that moves or is in transit, instrumentalities of transportation and communication, and floater risks; the NAIC Nationwide Marine Definition sets which risks may be written as marine.

  • Ocean marine covers hull, cargo, protection and indemnity, and freight, and uses general average to share sacrifices made to save a voyage among all interests.

  • A personal articles floater schedules valuable items such as jewelry, furs, cameras, musical instruments, fine arts, stamps, and coins with open-perils coverage that applies anywhere in the world.

  • Commercial floaters include contractors equipment, bailee's customers, installation, and equipment dealers forms, and ISO divides commercial inland marine into filed and nonfiled classes.

  • Valuable papers and records coverage pays the cost to research, replace, or restore lost information, while accounts receivable coverage pays sums the insured cannot collect because records were destroyed.

What "Marine" Means

Ocean marine insurance is the oldest form of insurance, covering ships and their cargoes. Inland marine grew out of it to cover goods moving over land and, later, property that is mobile or connected with transportation and communication. Because marine forms were historically flexible and less regulated, insurers tried to write ordinary fire risks as "marine." The Nationwide Marine Definition, adopted by the NAIC, now describes the risks that may be written as marine or inland marine insurance:

CategoryExamples
ImportsGoods in transit to the U.S. and while awaiting further transit
ExportsGoods in transit to other countries
Domestic shipmentsGoods on trucks, rail, or air carriers, including motor truck cargo
Instrumentalities of transportation and communicationBridges, tunnels, piers, wharves, pipelines, power and phone lines, radio and television towers
Personal property floater risksPersonal articles, personal property, and similar floaters for individuals
Commercial property floater risksContractors equipment, installation, bailee's customers, equipment dealers, signs, valuable papers, accounts receivable, and other mobile or specialized property

The Illinois mine subsidence law expressly excludes marine and inland marine policies from its definition of "policy," so those policies need not include mine subsidence coverage (215 ILCS 5/802.1(h)).

Ocean Marine Essentials

CoverageWhat It Protects
HullThe vessel, including machinery and equipment
CargoGoods carried, often on a warehouse to warehouse basis covering land legs of the journey
Protection and indemnity (P&I)The shipowner's liability for injury, death, and damage to others
FreightThe carrier's loss of freight charges when cargo is lost

Average means partial loss:

  • Particular average is a partial loss that falls on one interest, such as cargo damaged by seawater.
  • General average is a voluntary sacrifice or extraordinary expense made to save the voyage, such as jettisoning cargo in a storm. All interests, including the ship and every cargo owner, share the cost in proportion to their values.
  • Free of particular average (FPA) wording limits partial-loss coverage.

Ocean marine policies carry implied warranties: the vessel is seaworthy, there will be no deviation from the intended route, and the voyage is legal. Constructive total loss allows the insured to abandon a vessel or cargo to the underwriter when recovery or repair would cost more than its value, an exception to the ordinary property rule against abandonment.

Personal Inland Marine Floaters

A floater covers property wherever it is located, so the coverage "floats" with the property.

Personal Articles Floater (PAF)

The PAF, or a scheduled personal property endorsement to a homeowners policy, schedules valuable items by class and amount:

  • Typical classes: jewelry, furs, cameras, musical instruments, silverware, golfer's equipment, fine arts, postage stamps, and rare and current coins.
  • Perils: open perils ("risks of direct physical loss"), worldwide, generally including mysterious disappearance and accidental loss, subject to exclusions such as wear and tear, insects or vermin, inherent vice, war, and nuclear hazard. Fine arts usually exclude breakage of fragile items unless caused by specified perils.
  • Deductible: often none.
  • Valuation: most classes pay the least of actual cash value, the cost to repair or replace, or the scheduled amount; fine arts are usually written on an agreed value basis.
  • Newly acquired property: typically covered automatically for 30 days (90 days for fine arts) up to a percentage of the class limit, if the insured reports it and pays premium.
  • Pair or set clause: if one item of a pair or set is lost, the insurer may repair or replace it to restore the set, or pay the difference between the value of the set before and after the loss; it does not have to pay for the whole set.

Why it matters. Homeowners forms limit theft of jewelry to $1,500 and theft of firearms and silverware to $2,500. A floater removes those limits for scheduled items and covers losses, such as a ring falling down a drain, that named-peril personal property forms do not cover.

Personal Property Floater (PPF)

A personal property floater covers all of the insured's unscheduled personal property worldwide on an open-perils basis, with a deductible. It was more common before homeowners policies packaged personal property coverage; it is still used for people who travel or have no residence policy.

Commercial Inland Marine

Filed and nonfiled classes

ISO divides commercial inland marine into:

  • Filed classes, written on standardized forms filed with regulators, such as accounts receivable, camera and musical instrument dealers, commercial articles, equipment dealers, film, floor plan, jewelers block, mail, physicians and surgeons equipment, signs, theatrical property, and valuable papers and records; and
  • Nonfiled classes, written on insurer-drafted or manuscript forms, such as contractors equipment, bailee's customers, installation, transportation and transit, motor truck cargo, and electronic data processing equipment.

Common commercial floaters

FloaterCoversAdjuster Notes
Contractors equipmentMobile tools and equipment (bulldozers, cranes, scaffolding) anywhereOften scheduled with agreed values; theft and overturn are frequent claims
InstallationMaterials and equipment a contractor is installing, until accepted by the ownerFills the gap between delivery and completion
Bailee's customersCustomers' property in the care of a laundry, dry cleaner, or repair shopCan pay regardless of the bailee's legal liability to preserve customer goodwill
Jewelers blockA jeweler's stock and customers' goods, on and off premisesStrict security warranties
Equipment dealersMobile equipment held for sale by dealersExcludes autos and trucks
SignsNeon, fluorescent, and similar signsOpen perils, with breakage exclusions during installation
Transit / motor truck cargoGoods in transit, by the owner or as a carrierCheck the bill of lading and the carrier's legal liability

Valuable Papers and Records

Valuable papers and records are inscribed, printed, or written documents, manuscripts, and records, such as abstracts, books, deeds, drawings, films, maps, and mortgages. Money and securities are excluded. Coverage is available as:

  • a $2,500 coverage extension in the building and personal property form, to research, replace, or restore lost information (see 5.1); and
  • the Valuable Papers and Records Coverage Form, a filed commercial inland marine form with higher limits and open perils.

How claims are measured. For scheduled irreplaceable items, the insurer pays the agreed or scheduled value. For unscheduled items, it pays the cost to research, replace, or restore the lost information, up to the limit, and generally only if it is actually replaced or restored. A public adjuster should document staff time, outside research costs, and reconstruction invoices.

Accounts receivable coverage is a separate filed class. It pays sums the insured cannot collect because records were destroyed, interest on loans needed to replace those funds, collection expenses above normal, and the cost to reconstruct the records.

Applying Inland Marine to Property Claims

When a client's loss involves property away from the premises, high-value items, contractors' tools, or customer goods, check whether an inland marine policy or endorsement applies before accepting a homeowners or commercial property sublimit. Floater coverage is often broader, frequently has no deductible, and may use agreed values that eliminate depreciation disputes.
