I have a cold kit in my boat now too. I dedicated a huge metal army can to my boat. It takes up a lot of room, but i have the room and some things had to go! I now carry a Full set of dry clothes, bibs, coat that are over sized so they will fit anyone. I carry lighter and waterproof matches. A box of the huge matches with fire starter and one of the BIG fire starter logs. It will burn 45 min on its own. Everyone should have a plan. Time is not on your side.
