You should drink two cups of water about two hours before you exercise. Dear Lifehacker, I've heard you need eight glasses of water every day, but I've also heard that it might be more or less. Some say too much water is bad, and many more say too little is bad.
The minimum amount of water considered necessary to stay in good shape is 1.3/4 pts (1 litre) per day. It is possible to survive with 2 to 5 oz (55 to 220 centiliters) per day. When you will be surviving at sea for an unknown duration of time, it is necessary to ration the water to the minimum needed to survive.
