Coast Gaurd Survival Activity

yesterday we also did an activity in engineering where we had to figure out which survival item was better out of a list of 15 and compare our choices to the coast gaurd. when i list these the number of importance that comes first is ours and the one that is second is the coast gaurd

A sextant- 10, 15
A shaving mirrior- 12, 1
Mosquito netting-6, 14
25 L of water- 1, 3
army rations-3, 4
Maps- 11,13
Seat cusion-14-9
10L of oil/petrol-9, 2
transistor radio-7, 12
plastic sheeting-4, 5
shark repellent-8, 10
rum-13,11
nylon rope-5, 8
boxes of choclate-15, 6
fishing kit-2,7

In my opinion the coast gaurd is to buyist because they are only trying to rescue you and we are trying to survive. I know they are closely related but seriously water comes first our of everything and of course sacraficing ryan.
