Not that the moon needs defending around here, but I thought I'd put in my
two cents.  I use the moon often when I navigate and have never found it be
problematic.  Quite the opposite.  During a long passage, I particularly
like the weeks when the moon's azimuth is from approximately 40 to 140
degrees away from the sun's azimuth.  On those days, I can often get a
quick, reliable sun/moon fix.  Beats a running fix!

On the other hand, there is the question of using a bright moon during
periods of total darkness.  Under the right conditions (a couple of days
either side of a full moon, and little or no haze) the horizon is quite
visible.  I've taken these shots a few times out of boredom or curiosity and
found them to be reasonably accurate.  The hard part is finding the horizon
amidst the glare from the reflected moon.  Certainly I felt comfortable that
I could get to within 5 or 10 miles of accurate.  I've also used the horizon
that is visible under a full moon to shoot stars.  Same results.  I wouldn't
want to depend on these sights during an approaching landfall, but it is
possible to get a rough idea of one's location.
