Flare Gun: Pick up one of the Coast Guard approved flare guns to light up your location at night.
Food Supply: Bring enough food packets to keep you going for a few days. American Red Cross sells some great ones that are small, but loaded with what your body needs. Not sure if they have any beer packets, though...
Paracord and Straps: Paracord can be used for a gazillion things and you can wear it as necklaces or bracelets for easy packing. And bring some straps for your hat, sunglasses, etc.
