What is the primary reason for having a life raft on board?

The primary purpose of having a life raft on board a naval ship is to provide a means of abandoning the ship in emergencies. Life rafts are essential safety equipment designed to ensure the survival of crew members in situations where the ship is compromised, such as during a fire, flooding, or other catastrophic events that make remaining on board dangerous.

Life rafts are equipped with survival gear and can accommodate multiple individuals, providing a temporary refuge until rescue can be achieved or until the situation is stabilized. Their design is focused on buoyancy and safety, allowing for a quick and orderly evacuation from the ship.

In contrast, the other options do not align with the purpose of life rafts. Carrying food supplies, for example, is not their function; life rafts do not serve as storage for provisions. They are not intended for fishing activities or transporting goods to shore, as these functions are more accurately performed by other types of vessels or equipment specifically designed for such tasks.
