Another, hopefully related, question: If the AC power in a marina is
wired incorrectly, and/or a boat is wired incorrectly, one can become
electrocuted by just getting in the water. How can one tell, short of
throwing in their cat/dog/ex-spouse/parent-in-law?

I'd like to clean the bottom of my boat, while it's
in the water. Is there a fairly easy and economical
way of breathing while a few feet below the surface?
A snorkle won't work because I'll be going under
a houseboat, but am wondering if a hose could
be made to work, or maybe a larger piece of tubing
with a hose attached so it's small enough to be held
in your mouth. Or something...?
