51. The Light List indicates that a light has a nominal range of 13 miles and is 36 feet high (11.0 meters). If the visibility is 7.0 miles and your height of eye is 25 feet (7.6 meters), at what approximate distance will you sight the light?

The light's visibility is limited by both its geographic range (approximately 12.9 nautical miles) and its luminous range in the given visibility (approximately 10 nautical miles). The actual sighting distance is the lesser of these two, which is 10 nautical miles.
