The Nominal range of the light is as stated 9 nautical miles. This is how far you can see that light on a dark clear night with a visual range of 10 nautical miles...
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.
