OK - the red lights are for a location where an obstacle is higher
than the published surrounding terrain for the approach path. IOW,
something is sticking up in the way or potentially in the way of a
pilot (right?).
Is the location where Judy has observed three red masthead lights such
a location?
How often are sailboats anchored where a red masthead light would be
required? Why should anchoring in such a location even be allowed?
How many of such locations are there in the world where a sailboat
could anchor that it would need a red masthead light?
How would a sailboat know that they needed a red masthead light for
that location and how would they comply? Would it be on the chart?
It is far more likely IMHO that the masthead lights are NOT an
approach path requirement, but just something that someone thought up
to sell to sailors.
