16.3 Cyber, Aviation, and Other Specialty Lines
Key Takeaways
- Cyber liability splits into first-party coverage (the insured's own breach-response, business-interruption, and cyber-extortion costs) and third-party coverage (liability to affected individuals and regulators); it is almost always written claims-made.
- Aviation insurance separates hull coverage (physical damage to the aircraft, often on an agreed-value basis) from liability, frequently using a combined single limit subject to a per-passenger sublimit.
- Inland marine policies cover property in transit or mobile equipment and are typically written open-peril with no coinsurance, including floaters such as the contractors equipment floater and electronic data processing coverage.
- Ocean marine has four parts - hull, cargo, freight, and protection and indemnity - and uses ancient concepts like general average and sue-and-labor that the exam still tests.
- Specialty lines such as terrorism (backstopped by TRIA), event cancellation, and difference-in-conditions fill gaps that standard property and liability forms exclude.
Cyber Liability Insurance
Cyber liability is the fastest-growing specialty line and addresses exposures the commercial general liability (CGL) policy largely excludes. It divides into two halves that mirror the structure of liability coverage generally.
| First-Party (the insured's own costs) | Third-Party (liability to others) |
|---|---|
| Breach response, forensics, customer notification | Liability to individuals whose data was exposed |
| Business interruption from a system outage | Regulatory fines and defense, where insurable |
| Cyber extortion and ransomware payments | Privacy lawsuits and PCI-DSS assessments |
Most cyber policies are written on a claims-made basis with a retroactive date, because a breach can be discovered long after the intrusion occurred.
Quick Answer: First-party cyber pays for the insured's own losses; third-party cyber pays what the insured owes to others harmed by the breach.
Worked Example
A retailer suffers a ransomware attack. First-party coverage pays a 150,000 dollar forensic and notification bill plus 90,000 dollars of business-interruption loss while systems are down. Third-party coverage later responds to a class-action privacy suit by affected customers. A standard CGL would pay none of this - data is generally not tangible "property damage," and the policy excludes the exposure.
Aviation Insurance
Aviation insurance separates physical damage to the aircraft from liability, much as auto coverage does.
| Component | Covers |
|---|---|
| Hull | Physical damage to the aircraft, frequently on an agreed-value basis |
| Liability | Bodily injury and property damage to others, including passengers |
Liability is commonly written as a combined single limit (CSL) with a per-passenger sublimit. For example, a policy may show a 10,000,000 dollar CSL with a 1,000,000 dollar per-passenger cap, so a single injured passenger recovers no more than 1,000,000 dollars even though the overall limit is far higher.
Inland Marine
Inland marine insures property that moves, is in transit, or is held by others, plus instrumentalities of transportation and communication. Two hallmarks make it exam-friendly: it is usually written open-peril (all risks not excluded) and typically carries no coinsurance clause.
| Common Inland Marine Form | Insures |
|---|---|
| Contractors equipment floater | Mobile tools and machinery at job sites |
| Electronic data processing (EDP) | Computers, media, and sometimes data |
| Bailee coverage | Customers' property in the insured's care (e.g., a dry cleaner) |
| Personal articles floater | Scheduled jewelry, furs, fine art |
The defining theme is mobility or the property's value not being tied to a fixed location - the so-called "nationwide marine definition" governs eligibility.
Ocean Marine
Ocean marine is the oldest line of insurance and has four coverage parts.
| Part | Insures |
|---|---|
| Hull | The vessel itself |
| Cargo | Goods being shipped |
| Freight | The shipping revenue lost if cargo is not delivered |
| Protection and Indemnity (P&I) | Third-party liability of the vessel owner |
Two ancient concepts still appear on exams. General average requires all parties with an interest in a voyage to share proportionally in a loss voluntarily incurred to save the venture (for example, jettisoning cargo to save a sinking ship). The sue-and-labor clause obligates the insured to take reasonable steps to minimize a loss, with those costs reimbursed by the insurer.
Other Specialty Lines
- Terrorism: Standard policies may exclude terrorism, but the Terrorism Risk Insurance Act (TRIA) creates a federal backstop and requires insurers to offer terrorism coverage for certified acts.
- Difference-in-Conditions (DIC): A broad standalone policy that fills gaps in underlying property coverage, often adding flood and earthquake.
- Event cancellation: Reimburses lost revenue and expenses when a covered event is cancelled.
Common Exam Traps
- Cyber data is not CGL "property damage" - that exclusion is why a separate cyber policy exists.
- Aviation per-passenger sublimit caps a single claimant even when the CSL is much larger.
- Inland marine has no coinsurance and is open-peril - do not apply an 80 percent rule.
- General average spreads a voluntary sacrifice across all interests, not just the owner of the jettisoned cargo.
- TRIA requires an offer, not automatic inclusion of terrorism coverage.
Reading the Nationwide Marine Definition
The line between inland marine and standard commercial property turns on the nationwide marine definition, a regulatory list of what may be written as marine. Eligible classes include property in transit, instrumentalities of transportation and communication (bridges, tunnels, pipelines, radio towers), property held by a bailee, and mobile equipment whose value is not anchored to one location. If property simply sits inside a building at a fixed address, it belongs on a commercial property form, not inland marine.
This distinction explains why inland marine carries no coinsurance and is written open-peril: mobile and high-value property is hard to rate by location, so the line uses scheduled values and floaters instead of a coinsurance penalty.
Watercraft, Yacht, and Boatowners Forms
Recreational marine exposures bridge personal and commercial lines. A yacht policy typically blends ocean-marine principles - an agreed-value hull part and a protection and indemnity liability part - for larger pleasure vessels. Smaller craft are written on a boatowners or outboard motor and boat package that resembles a homeowners-style form, pairing physical damage with liability and medical payments.
The exam wants candidates to recognize that navigation territory and lay-up (out-of-water) warranties are conditions on marine hull coverage: operating outside the agreed waters, or in the water during a warranted lay-up period, can suspend coverage. These warranties are stricter than ordinary policy conditions because marine insurance descends from a tradition of strict good faith.
A company's network is breached and customer data is exposed. Which coverage pays the insured's own forensic investigation and customer-notification costs?
An aviation liability policy shows a 10,000,000 dollar combined single limit with a 1,000,000 dollar per-passenger sublimit. A single injured passenger has a 1,800,000 dollar claim. How much can that passenger recover under the policy?
