What does jettison mean in marine insurance?

In the context of marine insurance, the term "jettison" refers specifically to the act of throwing goods overboard to lighten the load of a vessel. This is often done in emergency situations where a ship is in danger, such as during a storm or when it is at risk of sinking. By jettisoning cargo, the crew attempts to improve the vessel's stability and safety, making this action a crucial part of managing maritime peril.

Jettisoning is generally recognized in marine insurance as a valid and sometimes necessary practice, and policies may cover the loss of goods that have been jettisoned under specific conditions. In contrast, the other options do not accurately describe the term. Securing a vessel from damage refers to preventative measures rather than the act of discarding cargo. Retrieving lost items pertains to salvage operations, and delaying shipping under adverse conditions is a logistical decision unrelated to the act of jettisoning. Understanding this term is vital for anyone working in marine insurance, as it highlights an essential concept connected to risk management and liability in maritime operations.
