Some time ago there was a post asking how it is that a few of the soda pop
cans stored on board could be empty when they were opened. A thoughtful
responder indicated that vibration can cause a pin hole leak that slowly
drains the can. I have had this happen to me and I accepted this response but
one thing bothered me: I happen to know that there is not a single soft drink
or beer canning plant in the state of Alaska. Every single can is transported
to Alaska from Washington State by ship or barge. And yet there have not been
complaints about this occurring in Alaska. I know because I spent 33 years
with one of the companies that hauls the container loads of product. As I was
stocking up for the summer at Memorial Day sale prices the answer came to me.
Look at how every single can is stowed on the store shelves: every single can
is vertical. But when we pick up a 12-pack we turn it 90 degrees so we can
carry it by the punch out handle. And, unlike the pros, we carry it that way
on our little ships and now the cans are on their sides rubbing against each
other with each roll of the vessel. I just restowed my soft drink supply so
that the cans are verical and I suspect that I won't have the problem again.
And God bless all the guys and gals in the service of our country.

My answer based on actual experience and always of course open to the real
answer from Marin, is that when cans are stored in actual metal contact with
each other, and different types of cans are stored, electrolysis happens in
the presence of bilge air (damp) causing pin hole leaks at the point of
contact. The electrolysis happens over a lengthy period of time so we might
call this Forgotten Can Syndrome (FCS). Those with thirst greater than
budget will not have experienced FCS. The results of the leaks do respond to
a mornings worth of elbow grease and a coat of paint in the affected locker.
