11.2 Ocean Marine Insurance
Key Takeaways Explain This Topic AI
Ocean marine is the oldest commercial insurance line; Lloyd's of London began in Edward Lloyd's coffeehouse in the 1680s as a marketplace for insuring ships and cargo
Four core coverages: Hull (the vessel), Cargo (goods at sea), Freight (the shipping revenue), and Protection & Indemnity / P&I (maritime liability)
Perils of the sea include storm, sinking, stranding, collision, and jettison; inherent vice, ordinary wear, and delay are excluded, and war requires separate coverage
General average forces all parties to share proportionally when property is voluntarily sacrificed for the common safety; particular average is a partial loss borne by the owner alone
The Sue and Labor clause obligates the insured to minimize loss and pays those expenses in addition to the loss; warranties (seaworthiness, legality) are strictly enforced

The Oldest Insurance Line
Ocean marine insurance predates fire and life insurance by centuries. The modern market traces to Edward Lloyd's coffeehouse in London in the 1680s, where shipowners and merchants found underwriters willing to subscribe to portions of a voyage's risk — the origin of today's Lloyd's of London.
Quick Answer: Ocean marine insures vessels, cargo, shipping revenue, and maritime liability for over-water commerce, organized into four coverages: hull, cargo, freight, and protection & indemnity.
Unlike most P&C lines, ocean marine is governed heavily by admiralty (maritime) law and long-settled doctrines such as average and sue-and-labor. The exam rewards knowing these doctrines, not just the coverage names.
The Four Core Coverages
- Coverage What It Insures Key Clause/Detail
- Hull The vessel, machinery, equipment Running-down (collision liability) clause
- Cargo Goods shipped by sea Often "warehouse to warehouse"
- Freight The shipping revenue lost if cargo never arrives Protects the carrier's/shipper's income
- Protection & Indemnity (P&I) Maritime liability Crew injury (Jones Act), pollution, dock damage
The running-down clause (RDC) within hull coverage pays the insured vessel owner's liability for collision with another vessel — a liability item carried inside a property coverage, which surprises candidates. Broader liabilities (crew, passengers, pollution, fixed objects like piers) fall to P&I .
Perils of the Sea and What Is Excluded
"Perils of the sea" means fortuitous, accidental dangers — not every peril encountered on the sea.
- Covered (Perils of the Sea) Excluded
- Storm, heavy weather, sinking Ordinary wear and tear
- Stranding, grounding Inherent vice (cargo that self-spoils)
- Collision, jettison Delay (even if a peril caused it)
- Fire, lightning, piracy War, strikes, riots (separate coverage)
Inherent vice — fruit that rots, steel that naturally rusts in humid holds — is a classic excluded trap. The cargo's own nature, not a sea peril, caused the loss.
Average: General vs. Particular
In marine law, "average" means a partial loss. Two kinds appear constantly on the exam.
General Average
When property is voluntarily and reasonably sacrificed for the common safety of the whole maritime venture, all parties — shipowner and every cargo owner — share the loss proportionally to the value saved. A general average adjuster computes each party's contribution.
Example: A fire threatens a freighter. The captain orders 200 of 1,000 containers jettisoned to save the ship and remaining cargo. Under general average, all cargo owners and the shipowner contribute pro rata — the unlucky owners of the dumped containers are reimbursed by everyone who benefited.
Particular Average
A partial loss that is accidental and falls only on the owner of the damaged property — no sharing. Seawater spoils one shipper's cargo in a storm; that shipper alone bears it (subject to their own cargo policy).
- Doctrine Trigger Who Pays
- General average Voluntary sacrifice for common safety All parties, pro rata
- Particular average Accidental partial loss Owner of the lost property alone
- The Sue and Labor Clause
The Sue and Labor clause requires the insured to take reasonable steps to prevent or minimize an insured loss. The insurer reimburses those expenses in addition to (over and above) the policy limit, encouraging salvage efforts even near the limit.
Example: A grounded cargo ship's insured pays $300,000 to a salvage firm to refloat it and recover cargo. Even if the loss already approaches the limit, sue-and-labor costs are paid additionally.
Implied Warranties (Strictly Enforced)
Marine policies impose strict implied warranties — breach can void coverage even without causation:
Seaworthiness — the vessel is fit for the voyage.
Legality — the venture is lawful.
No deviation — the vessel follows the customary route without unjustified detour.
Common Exam Traps
General vs. particular average is the single most-tested ocean marine distinction — memorize "general = shared, particular = owner alone."
P&I vs. hull collision. Hull's running-down clause covers vessel-to-vessel collision liability; P&I covers crew, passengers, pollution, and damage to fixed objects.
Sue and labor pays extra , not within the limit.
Cargo Clauses and the Warehouse-to-Warehouse Rule
Ocean cargo coverage is shaped by standardized Institute Cargo Clauses (historically labeled A, B, and C). Clause A is the broadest, an open-peril form; Clauses B and C are progressively narrower named-peril forms. A cargo policy typically attaches on a warehouse-to-warehouse basis — coverage runs from the shipper's warehouse, through the ocean voyage, to the consignee's final warehouse — so the cargo is protected during the inland legs at each end, not merely while afloat.
The Free of Particular Average (FPA) clause is a classic exam term: an FPA cargo policy pays a partial loss only if it results from a major peril such as stranding, sinking, burning, or collision, excluding ordinary partial sea damage.
Coinsurance, Valuation, and the Jones Act
Ocean marine cargo is usually written on a valued (agreed amount) basis — the policy states the value and pays it without depreciation, which suits the difficulty of appraising goods after a sinking. Hull coverage may carry a coinsurance clause unusual to property candidates, because owners are expected to insure to a high percentage of value. Liability for crew injury deserves special note: under the Jones Act , a seaman injured in the course of employment can sue the vessel owner for negligence, and these claims fall to P&I rather than ordinary workers compensation, because seamen are excluded from most state WC systems.
Recognizing that the Jones Act routes maritime crew injury into P&I — not workers comp — is a high-value exam distinction.
