What is the drinking water requirement per person in a lifeboat?

The requirement for drinking water per person in a lifeboat is established at 3 liters per day. This amount is considered the minimum to sustain an individual’s hydration needs under survival conditions. In emergencies, where individuals may be under stress and exposed to elements such as heat, maintaining proper hydration is crucial to prolonging survival and maintaining health.

This guideline is based on the physiological needs of the body and helps account for activities and environmental factors that could increase water loss, such as perspiration and breathing in a dry environment. Thus, having a minimum standard ensures that sufficient amounts of water are available for each person during a critical period, where access to clean water is severely limited. This standard is recognized internationally, which emphasizes its significance in emergency preparedness and response scenarios.
