What is an essential item to have in a lifeboat?

Having life jackets in a lifeboat is essential for ensuring each person's safety in the event of an emergency at sea. Life jackets provide buoyancy and help prevent drowning, allowing individuals to stay afloat in the water until rescue operations can be conducted. They are crucial for minimizing the risk of a person succumbing to fatigue or injury while waiting for help.

Other items mentioned, like extra clothing, food supplies, and a compass, can also be important for certain circumstances but do not directly address the immediate and critical need for personal flotation and safety when abandoning a vessel. Life jackets are a fundamental piece of safety equipment mandated by maritime regulations, ensuring that every person has the necessary means to survive if they end up in the water.
