Joel,
this, actually, jives well with what I said about sailing in-shore. The same
applies if you are sailing in close quarters. If you see the lights at the deck
level, then there is no advantage in having them at the top of the mast. The
opposite is true, as well. If you cannot see the deck lights, the top of the
mast lights have an advantage.

Marek,
one other difference: I find it harder to judge the distance of others boats
if they have a masthead light. It only really matters when racing and I am on
port - otherwise, I stay away. AIS helps if the other boat is so equipped.

It is kind of funny how a “steaming light” can many people confused.
The main point is that a sailboat is a sailboat and boat under power,
depending on its current situation at the time (if the engine is running, it is
a power boat, if it is not running, it is a sailboat (the actual term is “in
use” (not “engine running”), but from what I read so far, if your engine is
running and you are simply out of gear, you would be still considered “under
power”)).
The lights configuration has to reflect what you are.
A sailboat (let’s not dwell on the length at this point) needs the side
lights (red and green) and the stern light (white).
A power boat needs the same side lights and an all around white light.
How you accomplish the above is up to you (or the boat manufacturer).
The most common approach is to have an extra “steaming light” that closes the
circle - your stern light plus the steaming light provide full 360 degrees
white light. This way you have one switch to turn your sailing lights (side and
stern) and another one to turn the steaming light, when you turn on the engine.
Another option is to have a full circle white light (e.g. on top of the mast)
and use your side and stern lights when sailing and the side lights and the
full circle white light when under power. This requires to have a separate
switch for your stern light (and of course one for the full circle light),
because if you use full circle light, you have to switch your stern light off.
You cannot repeat any prescribed light so, if you have tricolour on the top
of the mast, you cannot use the side (bow) lights or vice versa.
People who sail off shore tend to put a tricolour on the top of the mast for
a number of reasons. One is that it is only one bulb (instead of three).
Another is that, especially with some waves, the deck level lights are not
visible from afar. My personal experience is that you cannot see them from more
then two wavelength away. But you cannot use the tricolour AND the deck level
lights at the same time.
People who sail in-shore or in coastal water would say that a light at the
masthead is of no use, because nobody looks that high up. Even an anchor light
at the top of the mast might be too high on some anchorages.
Interestingly, the same discussion is (was) happening at the Sailboat Owners
Forum.

Sorry for the rookie question but what is the steaming light?
For sailboats I am aware of the deck bi-color, masthead and stern lights,
tri-color (which is mounted on the mast and used as an alternate to the deck
mounted bi-color and stern lights, and the anchor light. Is “steaming light”
another term for masthead light?

… and I could could buy a bigger (C&C!) boat if I had a dollar for every time
I have seen the tri-color AND the ship’s running lights on at night. Here’s
another one that I found “amusing”, sailboat under power, tri-color light on,
and the steaming light lit. Now there’s an interesting lighting configuration.

Bob, a tricolor is indeed a substitute for deck level running lights. But
it may only be used while sailing. And it should never be used in addition to
deck level lights.
