Inland marine vs. ocean marine insurance
Ocean marine insurance covers ships and their cargo during transport over water, while inland marine insurance covers property being transported over land, movable property, and instrumentalities of transportation such as bridges and tunnels.
Ocean marine and inland marine are two branches of insurance that both grew out of covering goods in transit, but they apply to different exposures. Ocean marine insurance is one of the oldest forms of insurance, covering vessels and cargo moving over water. Inland marine insurance developed later to cover property once it left the ship and continued its journey over land — and it has since expanded to cover many types of movable property that never touch a waterway.
Ocean marine policies are typically divided into four coverages: hull insurance on the vessel itself, cargo insurance on the goods being shipped, freight insurance on the shipping revenue the carrier would lose if cargo is destroyed, and protection and indemnity (P&I), the liability component covering injury and damage caused by the vessel's operation.
Inland marine insurance covers domestic goods in transit by truck or rail, property held by bailees such as dry cleaners and repair shops, mobile equipment like contractors' tools, and instrumentalities of transportation and communication — bridges, tunnels, piers, and communication towers. Personal inland marine coverage, often written as a personal articles floater, insures valuable movable items such as jewelry, furs, and cameras that standard homeowners policies limit. Because the property moves, inland marine policies "float" with it, which is why they are often called floaters.
The property and casualty insurance licensing exam tests both lines: expect questions distinguishing water transit from land transit, identifying the four ocean marine coverages, and recognizing inland marine's role in covering movable property and instrumentalities of transportation.
Key takeaways
- Ocean marine insurance covers vessels and cargo transported over water; inland marine covers property transported over land and movable property.
- Ocean marine coverage divides into hull, cargo, freight, and protection and indemnity (P&I).
- Inland marine covers goods in transit, bailee exposures, mobile equipment, and instrumentalities of transportation like bridges and tunnels.
- Inland marine policies are called floaters because coverage follows the property as it moves.
- The P&C licensing exam tests the water-versus-land distinction and the components of each line.
