- Q182 - Navigation General: Near Coastal
112. The Light List shows that a navigational light has a nominal range of 10 miles and a height above water of 38 feet (11.6 meters). Your height of eye is 52 feet (15.8 meters) and the visibility is 11.0 miles. At which approximate range will you first sight the light?
The light will first be visible at approximately 10.5 miles. Visibility is limited by the light's brightness, not the horizon, as the luminous range (10.5 miles) is less than the geographic range (15.6 miles).
