- Q183 - Navigation General: Oceans
122. The Light List shows that a navigational light has a nominal range of 12 miles and a height above water of 25 feet (7.6 meters). Your height of eye is 30 feet (9.1 meters) and the visibility is 0.5 mile. At what approximate range will you first sight the light?
Visibility of 0.5 mile significantly reduces the light's effective range. The luminous range, which accounts for atmospheric conditions, is approximately 1.4 miles, limiting the sighting distance to that value.
