How many plugs must life boats have for each hole?

Life boats are critical safety devices on vessels, and their design adheres to specific safety standards to ensure effectiveness during emergencies. Each lifeboat must be equipped with at least two plugs for each hole. This requirement addresses potential damage that may occur, ensuring that even if one plug fails or becomes compromised, the second plug can still maintain buoyancy and integrity, providing an essential contingency for the craft's safety.

The rationale behind this specification is rooted in redundancy—the principle that having multiple safety features can significantly reduce the risk of failure in critical systems. In the context of lifeboats, this redundancy is crucial in emergency situations where reliability can mean the difference between life and death.

Understanding this aspect of lifeboat design is essential for operational readiness and compliance with safety regulations, which mandate such specifications to enhance survivability at sea.
