765. The Light List indicates that a light has a nominal range of 8 miles and is 48 feet (14.6 meters) high. If the visibility is 6 miles and your height of eye is 35 feet (10.7 meters), at what approximate distance will you sight the light?

The limiting factor is the 6-mile visibility, which restricts the sighting distance to approximately 5.9 nautical miles. This distance is less than the geographic range determined by the light's and observer's heights, so visibility dictates the actual sighting distance.
