 I've never heard of a requirement for an anchor light in a mooring field 
 for yachts, especially around here. Still a good idea though.

Stupid twit! And you CLAIM to have passed the USCG license exam and studied 
the COLREGS.
You are pathetic, man pathetic! What a poor example you are to us competent 
and real captains!
What don't you understand about this?
Rule 30
(a)  A vessel at anchor shall exhibit where it can best be seen: in the fore 
part, an all-round white light or one ball;  at or near the stern and at a 
lower level than the light prescribed in subparagraph (i), an all-round 
white light.
(b)     A vessel of less than 50 meters in length may exhibit an all-round 
white light where it can best be seen instead of the lights prescribed in 
paragraph (a) of this Rule.
(c)     A vessel at anchor may, and a vessel of 100 meters and more in 
length shall, also use the available working or equivalent lights to 
illuminate her decks.
(d)     A vessel aground shall exhibit the lights prescribed in paragraph 
(a) or (b) of this Rule and in addition, if practicable, [Inld] where they 
can best be seen;
two all-round red lights in a vertical line;  three balls in a vertical 
line.
(e)     A vessel of less than 7 meters in length, when at anchor not in or

(b) of this Rule.
(f)      A vessel of less than 12 meters in length, when aground, shall not

INTERPRETIVE RULES - INLAND
§ 90.1 Purpose
This part contains the interpretative rules for the Inland Rules. These 
interpretative rules are intended as a guide to assist the public and 
promote compliance with the Inland Rules.
§ 90.5 Lights for moored vessels
A vessel at anchor includes a vessel made fast to one or more mooring buoys 
or other similar device attached to the ocean floor. Such vessels may be 
lighted as a vessel at anchor in accordance with Rule 30, or may be lighted 
on the corners in accordance with 33 CFR 88.13.
So, try weaseling your ignorant way out of this one! Few if any of you 
reading this anchor in the few "Special Ancorages" that are available as 
most of them are very exposed to wind and sea and generally exist for the 
sake of large shipping interests waiting to come into port.
