Survival at Sea

In groups we were to come up with a specific order of importance for a list of items if ever lost at sea.
I chose a 25 liter container water as number one on my list of importance, followed by a case of army rations. As a last option, I chose the rum.
I think I had a lot of difficulty deciding the importance of the maps of the Pacific Ocean, as sextant and the radio because I felt they were all necessary for each other, but I didn't know that the radio was one way.
My team had decided that water and food were the two most important items to have if lost at sea like I did. As the last choice, we decided a floating seat cushion was pretty unnecessary. We were all mostly on the same page with the order so there wasn't much discrepency.
We were way off on almost everythin compared to the official Coastguard choices. I was surprised by the significance of a shaving mirror and wondered why water didn't come before food. I think eperiential data is more important because what makes sense to us as individuals doesn't always much up with how things should be. I think we know ourselves enough to decide what is more important for ourselves and know what we can handle and what we can't.
