In Toronto, the Island Airport's runways flight path is over the
harbour. Here, they've placed restriction markers at the ends of the
runways where no boat may enter. Additional to this, there are markers
that define and extended area that boats with masts of 60+' are
restricted from. Being a pilot, I can say that the red lights on the
tops of tall masts are for aircraft obstruction avoidance. They are
required when an obstacle is higher than the published surrounding
terrain for an approach path near an airport or when the obstruction is
high enough to extend into an airway (for example, the CN tower here in
Toronto). Just because and obstruction is moveable does not remove the
requirement to be able to be identified by aircraft.
Fair winds,
Mike

Anyway - people are saying, without seeing these red lights that Judy
speaks of, that they are for aviation warning purposes. If that is
true than of course they are needed, and maybe the range lights need
to be changed to a different color.
Are the masts with red lights on top taller than the other masts in
the anchorage? If not, then the red lights are probably an
affectation. Or else ALL the masts should have a red light on top and
they are all out of spec.
I got the idea from what Judy said that they were just ordinary height
sailboat masts.
Plus in most cases, if there is really a concern with airplanes low
enough to impact a sailboat mast, then maybe the sailboats should not
be anchored there at all. There's a place in Toronto in the path of
the runway where sailboats (or I think almost any boat) is restricted
from even being in that area let alone anchoring.
Really I think most of those red lights are for fixed structures, not
ordinary boats which will be moving around.

this case red lights, and these lights are combined with non-standard
lighting techniques, again, red mast lights, then can be great cause for
concern and danger. Thind about entering a harbour under these
conditions. Not good, unless you enjoy grounding your boat on rocks.
