So the max distance you can see that light is 9 nautical miles. The USCG would have to punch up the power of the light in order to see it at a greater range.
Absolutely, and may I add that the world may have to flatten out a bit as its curvature is a consideration. Also the range stated on a chart may be more realistic if seen from the bridge of a ship.
However, do your CG tests require a technically correct answer or a practical one?
