I've got one on board, although it's not required for a boat our size in the waters we normally cruise.
If I were to add additional nav lights beyond the standard deck level lights, I would not add the mast-top tri-color. Instead I would add the "red-over-green-sailing-machine" lights that I could use in combination with the deck-level lights.
I saw a very nice set of "red-over-green" lights on a larger sailboat in Annapolis. They achieved the "all-round" requirement by having a pair of 180 degree lights on each side of the mast. Unfortunately I did not have my camera handy - you don't see them very often.
