Typical cruising yachts use from 4 to 20 litres (1.05 to 5.28 gallons) per person per day, the average probably being about 6 litres (1.59 gallons). The minimum water intake required to maintain body hydration is 1.5 litres (0.4 gallons) per day. The amount of water that is required for a person to consume is dependent on different factors. Some of these factors include weight, height and gender. Men on average needs a greater amount of water than women do.
