Final answer:
Jettison is the act of throwing cargo overboard to save the ship, often during distressing situations such as storms, and has historical relevance, including in practices related to slavery and insurance fraud.
Step-by-step explanation:
Jettison is defined as the act of throwing cargo overboard to save the ship. This is particularly relevant in situations where a ship may be in distress due to a storm or risk of sinking. By lightening the ship, the crew hopes to prevent a complete disaster and save both the vessel and the lives of those on board.
Historical examples include the tragic case of the Zong in 1781, where the captain, in an attempt to claim insurance, ordered enslaved people to be thrown overboard during bad weather. Other instances involve crew members who, during a storm, may have to decide whether to jettison cargo to ensure the ship's buoyancy. Such decisions are made to prevent the ship from capsizing or being overwhelmed by the sea.
