You have chartered a yacht with friends, for the holiday trip of a lifetime across the Atlantic Ocean. Because none of you have any previous sailing experience, you have hired an experienced skipper and twoperson crew. Unfortunately, in mid Atlantic a fierce fire breaks out in the ships galley and the skipper and crew have been lost whilst trying to fight the blaze. Much of the yacht is destroyed and is slowly sinking. Your location is unclear because vital navigational and radio equipment have been damaged in the fire. Your best estimate is that you are many hundreds of miles from the nearest landfall. You and your friends have managed to save 15 items, undamaged and intact after the fire. In addition, you have salvaged a four person rubber life craft and a box of matches. Required:
Your task is to rank the 15 items in terms of their importance for you, as you wait to be rescued. Place the number 1 by the most important item, the number 2 by the second most important and so forth until you have ranked all 15 items. Decide upon the rank order of the following items:

a. Sextant
b. Shaving mirror
c. Five-gallon can of water
d. Mosquito netting
e. One case of army rations
f. Maps of Pacific Ocean
g. Seat cushion
h. Two-gallon can of oil-gas mixture
i. Small transistor radio
j. Shark repellent
k. Twenty square feet of opaque plastic
l. One quart of 160 proof rum
