14.4 Ocean Marine Coverages (Hull, Cargo, Freight, P&I)

The Oldest Line of Insurance

Ocean marine is the original form of commercial insurance, predating fire coverage by centuries and giving rise to many legal doctrines still tested today. It is lightly regulated - rates and forms are largely unfiled - and relies heavily on admiralty (maritime) law and long-established London clauses. An ocean marine policy typically assembles four principal coverages, sometimes called the four major interests:

1. Hull - physical damage to the vessel itself.
2. Cargo - the goods being transported.
3. Freight - the revenue/income the shipowner earns for carrying cargo.
4. Protection & Indemnity (P&I) - the shipowner's liability to others.

A candidate must be able to assign a given loss to the correct one of these four interests.

Because ocean marine is largely unregulated, its policies are highly negotiated and rely on standardized Institute Clauses drafted in London rather than ISO forms. The line is also the birthplace of doctrines that now pervade all insurance: utmost good faith (uberrimae fidei), which imposes an exceptionally strict duty of disclosure on the marine insured; insurable interest; indemnity; and subrogation. Candidates should expect questions that test these foundational doctrines in a maritime fact pattern.

Hull, Cargo, and Freight

Hull insurance covers physical loss or damage to the vessel and its machinery. It commonly includes a Running Down Clause (Collision Liability) covering the insured vessel's liability for striking another ship - a liability coverage embedded within a property form, which surprises candidates.

Cargo insurance protects the goods. It is written:

• Voyage policy - covers a single, specific trip from port to port.
• Open (reporting) cargo policy - covers all shipments of a regular shipper, who reports values periodically.

Cargo is typically written on broad Institute Cargo Clauses (A) (all-risk) or narrower (B)/(C) named-peril clauses. Inherent vice - loss from the nature of the goods themselves, such as fruit that spoils because a voyage is unusually slow - is excluded: the insurer covers fortuitous external loss, not natural deterioration.

Freight insurance protects the shipowner's expected earnings (the transportation charge) that would be lost if cargo cannot be delivered and the freight is not earned.

Protection & Indemnity and Marine Perils

Protection & Indemnity (P&I) is the shipowner's broad liability coverage - injury to crew and passengers, damage to docks and piers, pollution, and liability not covered by the hull collision clause. P&I is usually provided by mutual P&I Clubs rather than commercial insurers.

Classic perils of the sea include: stranding, sinking, collision, heavy weather, fire, jettison, and barratry (fraud or willful misconduct by the master or crew against the owner). Note: ordinary wear, tear, and inherent vice are NOT perils of the sea.

Unique ocean-marine clauses tested on the exam:

• Sue and Labor Clause - requires the insured to take reasonable steps to minimize loss; the insurer reimburses those expenses.
• Free of Particular Average (FPA) - excludes partial losses below a threshold.
• With Average (WA) - covers partial losses subject to terms.
• Implied warranties - of seaworthiness, legality, and no deviation from the planned route; breach can void coverage.

The seaworthiness warranty means the vessel must be reasonably fit for the voyage; the legality warranty means the venture must be lawful; the no-deviation warranty means the ship must follow the customary route without unjustified departure. A breach of any implied warranty can suspend or void coverage even if it did not cause the loss - a strictness unique to marine law that surprises property-and-casualty candidates accustomed to causation requirements. These warranties, the FPA/WA average terms, and the perils-of-the-sea list together form the most commonly tested ocean marine vocabulary after General Average.

General Average - The Signature Doctrine

General Average is the most heavily tested ocean marine concept. Under this ancient maritime doctrine, when a voluntary, reasonable sacrifice (or extraordinary expense) is made to save the entire venture from a common peril, all parties to the voyage share the loss in proportion to the value of their interests saved. A Particular Average, by contrast, is a partial loss borne solely by the owner of the lost property.

Worked example. A ship carries three shippers' cargo valued at $2,000,000 (Shipper A), $3,000,000 (Shipper B), and $5,000,000 (Shipper C); total saved venture = $10,000,000. To refloat after a grounding, the captain orders $400,000 of Shipper C's cargo jettisoned. Because the jettison was a voluntary sacrifice for the common good, it is a General Average loss shared by all:

Shipper C, whose $400,000 cargo was sacrificed, recovers $320,000 from A and B and absorbs only its own $200,000 share. Marine cargo policies pay each insured's General Average contribution.

The Four Ocean Marine Coverages

Ocean marine - the oldest line of insurance - protects vessels, cargo, and marine liability on the seas and navigable waters. The exam expects the four traditional coverages:

Implied Warranties

Ocean marine policies carry three implied warranties that need not be written to apply, and breach can void coverage:

1. Seaworthiness - the vessel is fit for the voyage.
2. No deviation - the vessel follows the customary route without unnecessary departure.
3. Legality - the venture is lawful.

These implied warranties are nearly unique to ocean marine and are a favorite exam contrast with the express warranties of land lines.

Particular Average, General Average, and Perils of the Sea

Ocean marine uses distinctive loss concepts. Particular average is a partial loss borne by the owner of the lost property alone. General average is a partial loss deliberately incurred for the common safety (jettisoning cargo to save the ship) - the loss is shared proportionally by all parties to the voyage (ship, cargo, freight). Perils of the sea (storms, sinking, stranding, collision) are the core insured causes, distinct from "perils on the sea" like fire or piracy.

Coverage Terms and Modern Marine Lines

Ocean cargo is often written with Institute Cargo Clauses (A, B, or C) ranging from open-peril (A) to limited named perils (C), and with warehouse-to-warehouse transit coverage. P&I clubs provide the liability layer for crew injury, cargo liability, collision liability not covered by hull, and pollution. A candidate should distinguish general average (shared) from particular average (borne alone) and recognize that freight insurance protects the carrier's earnings, not the cargo - the two most-missed ocean marine concepts.
