Out a through-hull is the best place for a water tank vent...into the
bilge a VERY poor second.

Why is the bilge such a poor second? The water goes in the bilge. The
bilge pumps pump it out. What's the problem?


At least both of those locations [bilge or through-hull] allow you to
flush out the vent by overflowing the tank out it each time you fill it.


Aside from the problems with galley-sink and shower that you
mentioned how do these locations disallow you from flushing the
water vent by overflowing the tank as you fill it? You overflow
the tank, it goes into the sink/shower and the vent is flushed, no?
