Stone Arrowheads: You can pick these up online and with some thread and sticks, make great hunting and defense companions. But a word of caution - be smart about the size of the ones you try and put in your carry-on.
Medical Sea Pack: In case you get injured or must survive days away from a doctor, you'll want to pick up a mini medical kit. Again, one that is built for ocean survival.
