The correct answer is two anchor lights. I just posted that.

I didn't post an answer right away because I didn't see
any correct responses. Your response Neal did not show
up on my newsreader. I just checked on Google Groups,
and saw that you, Capt Neal, were the one and only person
to post the correct answer. I awarded you 1 point on that
thread.

The barge question over fifty meters in a special anchorage area the
right answer is TWO anchor lights. Bart was wrong when he said one
anchor light was the right answer.
