Inland Marine Floaters and Transit Coverage
Inland marine grew out of ocean marine to cover property in domestic transit and other movable or instrumentality risks. The boundary of what may be written as inland marine is the NAIC Nationwide Marine Definition, which organizes eligible risks into six categories, including domestic shipments, instrumentalities of transportation and communication (bridges, tunnels, towers), and various floater classes. Transit coverage splits by duration and buyer: an Annual Transit Policy covers a shipper's own goods in transit by truck or rail continuously for a 12-month term, attaching automatically to every shipment without individual declarations; a Trip Transit Policy covers one named shipment. Both insure the owner's property interest - by contrast, Motor Truck Cargo Liability insures the motor carrier's legal liability for damage to customers' goods it hauls. Bailee forms protect businesses holding customers' property. Bailees Legal Liability pays only when the bailee is legally liable (negligence must be shown), while the broader Bailees Customers Form pays customers for loss regardless of the bailee's legal liability - valuable goodwill protection for dry cleaners, repair shops, and fur storers, and a gap-filler for the CGL care-custody-control exclusion. Cargo policies commonly carry a No Benefit to Bailee clause so carriers and warehousemen cannot take advantage of the shipper's insurance. Construction-adjacent floaters include the Contractors Equipment Floater for mobile machinery and the Installation Floater, which covers materials and equipment in transit and during installation but terminates when the purchaser accepts the installed work - a bright line that can strand a loss if the owner's property coverage has not picked up the completed work. Personal inland marine centers on the Personal Articles Floater (PAF), which schedules valuables - jewelry, furs, fine art, cameras, silverware - on an itemized, usually agreed-value basis with worldwide coverage. Newly acquired items in already-scheduled categories are automatically covered for up to 30 days from acquisition, capped at 25 percent of the category limit for most classes but only $10,000 for fine art. A pair-and-set clause addresses partial loss of matched pieces. On the pleasure-craft side, boat coverage divides around a 26-foot line - smaller craft fit boatowners packages while larger vessels are written as yachts, with yacht hulls placed all-risk on agreed value and subject to warranties like captain's license requirements.
Key rules
Annual transit covers the shipper's own goods automatically for a 12-month term.
Every shipment the insured originates attaches without individual declaration, subject to per-conveyance and per-occurrence limits; a trip transit policy covers a single named shipment instead.
Why the exam cares: Form-selection questions describe a frequent shipper wanting automatic ongoing coverage - annual transit is the tested fit.
Motor Truck Cargo insures the carrier's liability, not the owner's goods.
The trucker's legal liability for damage to customers' cargo is the insured interest; the shipper protects its own goods with transit insurance.
Why the exam cares: The owner-versus-carrier interest distinction is the classic inland marine discriminator.
Bailees Customers pays regardless of liability; Bailees Legal Liability requires negligence.
The Customers Form treats the bailee as promising return of the goods in good condition, protecting customer relationships; the legal-liability variant responds only to proven fault.
Why the exam cares: The exam contrasts the two variants and ties both to the CGL care-custody-control exclusion they fill.
The Installation Floater terminates at the purchaser's acceptance of the work.
Once the owner accepts the installed system, the contractor's floater is off risk; if the owner's property policy has not attached, a loss in the gap is uninsured.
Why the exam cares: Timeline questions place a fire days after acceptance and test who, if anyone, covers it.
PAF newly acquired items get 30 days of automatic cover, with a fine-art dollar cap.
Automatic coverage in scheduled categories runs 30 days from acquisition at up to 25 percent of the category limit - but fine art is capped at $10,000 because of valuation volatility.
Why the exam cares: Numeric questions buy a painting, skip the report, and test the $10,000 cap inside the 30-day window.
Numbers to memorize
- 6 — categories of insurable marine business under the NAIC Nationwide Marine Definition
- 30 days — automatic coverage window for newly acquired items under the Personal Articles Floater
- $10,000 — PAF automatic cap for newly acquired fine art (other categories: 25% of the category limit)
- 12 months — continuous term of an Annual Transit Policy attaching to every shipment
- 26 feet — customary dividing line between boatowners packages and yacht policies
Common traps
- Buying motor truck cargo to protect the shipper's goods — remember it covers the carrier's liability; the shipper needs an annual or trip transit policy.
- Assuming the Installation Floater runs until the project closes out — remember owner acceptance is the bright-line termination, and coverage gaps after acceptance are the tested outcome.
- Equating the two bailee forms — remember the Customers Form pays without regard to legal liability, while the Legal Liability form requires negligence.
- Applying the 25 percent newly-acquired cap to fine art — remember fine art carries its own lower $10,000 automatic cap during the 30-day window.
For every inland marine question, first ask whose property interest is at risk - the owner's, the carrier's, or the bailee's - and the correct form usually falls out immediately.
