RE: Epi Pen and Electronic Keys
I am no doctor but I work in medicine and I cannot see what allergy you might have that would require an epipen, especially if you sail in fresh water. Salt is different since you may get stung by some of the seafood swimming arround. Bees don't hang ou over lakes since there are not much flowers there.
Have fun out there and I will try to look around my harness...Leaving my bag on the beach with the ipod and the car keys might not be the best solution.
