The other answers--lightship, etc, as far
as I know are not correct, but may be using
this sort of display in practice.

The lightship answer was perhaps a bit obscure, since there are very few, if
any, still in service.

Notices to Mariners contain the following:

1949 - New York Harbor, South Channel
NM Oct 8 - "About Jan 1, 1950 Sandy Hook Experimental Lightship EXP will be
established 5850 yards, 94 degrees 30 minutes from Sandy Hook Light - red hull,
EXE in white on sides, white superstructure, buff mast and gallery. Flashing red
light every 6 seconds (1 second flash), 2000cp light at 40 feet visible 12
miles; electric chime diaphragm horn, 1 blast every 10 seconds (two second
blast), Class B radiobeacon, range 10 miles, 298kc, (._.. ), 60 seconds on, 120
seconds off during 1st and 4th ten minute period of each hour in clear weather;
continuous use in fog or low visibility. Note - lightship is unmanned and
controlled from ashore. Position: 40 27.5 - 73 56.4." (this would place it about
1.3 mi - 315 degrees from Scotland Lightship)

1950 - New York Harbor, South Channel
NM Jan 7 - "Establishment of Sandy Hook Experimental Lightship has been
postponed indefinitely."
(No further reference found)


Also, I believe a flashing red is used to signal that planes or helicopters may
not land.

Since a flashing red is also used to signal that a lock may not be entered, I
wonder if its also used to wave off "landing ships," or whatever the modern
equivalent is called.





Not that you are likely to see WIG flying
around soon. Also, part 2 of the question
logically follows, the WIG craft must stay
the heck away from other vessels who could
not avoid a WIG if they wanted to.

The main point I wanted to make was there
are new rules, and the rules have not been
updated except as addendums.

Thanks Jeff for posting the link to these.

If we want to carry on the discussion.

What are the other new changes to the
Rules of the Road?

A lightship?

Or how about an aircraft carrier, or ships that receive helicopters?

And of course, under the new rules, a WIG taking off or landing.

What sort of vessel must operate with
an all around flashing red light?

What right of way rights does it have?
