I like this idea/concept because the best equipment in the world does nothing for you if one doesn't have it with them when they need it. Being a towboat driver, I am constantly reminded of a historical fact: "Towboats, like Coast Guard Cutters have always done two things extremely well - BURN and SINK!!!
I carry a Buck 110, Leatherman, and a ball cap in a .45cal leather magazine pouch and a maglite (red lense and w/spare bulb) on my belt at all times. That, along with my life jacket (whistle, 6" & 8" Crescent wrenches, leather gloves, 3 cell "C" flashlight, and 1 spare pack of "C" bateries) does not constitute much equipment, in case of need.
I think I can do better, based on your idea and I Thank you for starting this thread.
