What is the required fuel carrying duration for a life boat?

The required fuel carrying duration for a lifeboat is 24 hours. This duration is established to ensure that in the event of an emergency, the lifeboat has sufficient fuel to operate for an extended period, allowing for safe navigation, maneuverability, and the ability to reach a rescue position.

Having a 24-hour fuel supply is critical because it ensures that survivors can signal for help, maintain radio communications if necessary, and avoid drifting too far from the intended rescue area. It also accounts for potential delays in rescue operations and the necessity to handle unexpected circumstances that may arise during a survival situation. This regulation is in line with the safety standards set forth in maritime safety conventions to enhance the survivability of individuals in distress at sea.

The other options do not meet the safety needs that a 24-hour fuel supply provides. For instance, a shorter duration like 12 or 18 hours may not sufficiently cover the time needed for rescue or could leave survivors dependent on precise and timely rescue operations, which cannot be guaranteed in all scenarios. Thus, the specification of 24 hours reflects a balanced approach that prioritizes safety and survivability in emergencies.
