Yeah, it seems like a lot. I was thinking I'd have to set the scale fairly small to justify all them. Maybe 400 to 800 miles across this map. But my instincts were based on *surviving* lighthouses. Back in the day, some stretches of coast warranted a beacon every ten miles, with clusters at complicated inlets and harbors that would be WAY out of line with what I'm willing to depict :-). Take a look at the lighthouses of Newfoundland or the lighthouses of Maine for instance.

So I'm going to set an era of maybe 1850-1900 equivalence, and I'll say these are just the principal open-sea navigation beacons... for harbor lights, see additional sheets. And maybe the width of this chart is more like 100-120 miles. I can't pretend it's much of a navigational aid anyway, unless I show channels and depths. <shrug> Maybe it's for canoeists, not ocean liners.
