Comment: It depends on your height above the water. You could only see 20 miles if you were well above sea level. If â¦you are standing more or less at sea level, with your eyes just a few feet above the water level, you could see only about 3 or 4 miles. For example: Eye level at 6 feet: horizon at about 3 miles.
1.17 times the square root of your height of eye = Distance to the horizon in nautical miles. For example, if your height of eye is 9 feet above the surface of the water, the formula would be: 1.17 times the square root of 9 = Distance to the horizon in nautical miles. 1.17 * 3 = 3.51 nautical miles. If you want to calculate the distance at which an object becomes visible, you must know your height of eye and the height of the object.
