14.4 Ocean Marine Coverages (hull, cargo, freight, P&I)

The Oldest Line of Insurance

Ocean marine insurance covers waterborne property and the liabilities arising from ocean transit. It is the oldest insurance line and remains largely non-filed / manuscript, written through admitted insurers, surplus lines markets, and Lloyd's syndicates. Because exposures vary by vessel, voyage, and cargo, ocean marine relies on utmost good faith (uberrimae fidei) - a heightened duty of disclosure that gives the insurer broad rescission rights if the insured conceals or misrepresents material facts.

Unlike most property lines, ocean marine policies are dominated by named-peril language drawn from centuries of admiralty practice, plus the famous 'all other perils' (Inchmaree) and 'perils of the sea' clauses.

Perils of the sea are fortuitous accidents peculiar to the sea - heavy weather, stranding, sinking, collision - not the ordinary action of wind and waves a voyage normally encounters. The Inchmaree clause (named for an 1887 court case) extends coverage to losses the perils-of-the-sea language alone would not reach, such as latent defects in machinery, boiler bursting, and negligence of the master or crew. Ocean marine also features warranties - promissory statements (seaworthiness, trading limits) whose breach can void coverage - reflecting the line's strict good-faith roots.

The Four Principal Coverages

An ocean marine program is built from four interlocking coverages:

P&I functions as the marine equivalent of liability insurance and is frequently provided by mutual P&I Clubs. The hull policy's Running Down Clause (RDC) / Collision Clause covers collision liability to another vessel, traditionally limited to a portion (often three-fourths) with the remaining one-fourth picked up by P&I.

Marine Clauses, Averages, and Sue & Labor

Ocean marine carries unique loss-sharing concepts the exam tests:

• Particular Average - a partial loss borne by the owner of the damaged property alone (e.g., seawater-damaged cargo).
• General Average - a partial loss voluntarily and intentionally incurred to save the entire venture (jettisoning cargo to refloat a grounded ship). All parties - hull, cargo, and freight owners - contribute proportionally to the sacrifice.
• Free of Particular Average (FPA) - a clause excluding partial cargo losses below a threshold, so the insurer pays only total losses or losses from major perils.
• Sue and Labor clause - obligates and reimburses the insured for reasonable expenses to minimize a loss after a peril strikes.
• Inchmaree clause - extends hull coverage to losses from latent defects, machinery breakdown, and crew negligence.

Worked Example: General Average Contribution

A grounded vessel is saved when the captain jettisons part of the cargo. The voyage values at risk are: vessel (hull) $4,000,000; cargo $1,500,000; freight $500,000 = $6,000,000 total. The jettisoned cargo sacrificed in the general-average act is $300,000.

Each interest contributes in proportion to its value at risk:

• Total at risk: $6,000,000; sacrifice: $300,000 -> contribution rate = $300,000 / $6,000,000 = 5%
• Hull contributes: 5% x $4,000,000 = $150,000
• Cargo contributes: 5% x $1,500,000 = $75,000
• Freight contributes: 5% x $500,000 = $37,500
• Total contributions = $262,500, plus the sacrificing cargo owner bears its own 5% share ($15,000 of the $300,000), reimbursing the net loss.

Trap: general average is a shared loss - the owner whose cargo was jettisoned is reimbursed by all interests, unlike particular average, which the damaged owner bears alone.

Finally, remember how ocean marine relates to land coverage. Cargo insurance frequently includes a warehouse-to-warehouse clause so goods are covered door to door, with inland marine transit insurance picking up the over-land legs and ocean cargo covering the waterborne portion. The handoff at the over-water boundary is the single most-tested ocean-vs-inland distinction, so anchor every marine question on whether the property is on land, in transit over land, or actually waterborne at sea.

The Four Ocean Marine Coverages and Key Clauses

Ocean marine insurance - the oldest line - covers ships, cargo, and related exposures on the seas. It comprises four coverages the exam tests by name:

Ocean marine uses unique clauses:

• General Average - when cargo/vessel is voluntarily sacrificed to save the venture, all parties share the loss proportionally.
• Particular Average - a partial loss borne by the property owner alone.
• Perils of the Sea - heavy weather, stranding, sinking, collision.
• Sue and Labor / Free of Particular Average (FPA) clauses adjust recovery.

Exam trap: General Average = a voluntary, intentional sacrifice for the common good, shared proportionally by ALL interests; Particular Average = an accidental partial loss borne by the one owner. The Protection & Indemnity (P&I) coverage is the liability portion of ocean marine (akin to the CGL of the sea), covering crew injury, cargo liability, and collision/pollution liability the hull policy excludes. Ocean marine is largely unregulated as to rates/forms because of its long admiralty tradition.
