If you have run your ship aground on the rocks. Your head is above water but help could be along time reaching you.
Option 1; Eat and drink all your supplies at once, then what?
Option 2; Would it be wiser to ration out you supplies to survive longer to have a better chance to be alive when help arrives, and give your crew more time to refloat your ship?
Clear heads are needed now more than ever. Think of future rather than right now.
