Water does not have zero resistivity. If there is a strike on the water a
potential difference will appear across you in the water. This will most
likely be enough to pass more than 30ma through your body. This is highly
likely to be fatal.


Your body, being loaded with salts, is a better conductor than fresh
water, so the current will preferentially go through you.

Best place either in a car, or curled up in a ditch out of the water.


Thanks for that, I knew I'd missed something. It does raise the question of
why fish aren't affected though.


They are. A standard fishing technique is to generate a current through
the water which stuns/kills the fish, and you simply pick up the ones
which float to the top.
