Ahh - now I see what Arild was talking about - we were talking about two
different types of Anchorages!
The Special Anchorage areas that I was describing (and that 33CFR110 applies to)
were small boat anchorage areas, where no anchor lights need be displayed a
night on boats below 65' (no anchor light is what makes them Special, and of
importance to marinas and yacht clubs).
The large vessel anchorage areas out in the roadstead or estuary are indeed
sometimes marked on the charts with a anchor symbol just as Arild had said,
although many times they are just marked with a circle with the anchorage number
inside of it, as is normally done in the New York, Norfolk or Annapolis big ship
anchorage areas. The only place I've seen those anchorages described in in Chart
#1, but other than describing the various ways to denote them on the chart
(there are 12 different ways - including one for quarantine, one for explosives
and two for sea planes), there is not much else that I've found.
