For an observer standing on the ground with h = 2 meters (6 ft 7 in), the horizon is at a distance of 5 kilometers (3.1 mi).
The Earth curves about 8 inches per mile. As a result, on a flat surface with your eyes 5 feet or so off the ground, the farthest edge that you can see is about 3 miles away
Humans can see from 380–740 nanometers (nm)
So, the answer is no, if you can only barely see 3 miles away, then you wouldn't be able to read the name of a boat 3.1 miles away.
Answer:Which excerpt from "The Enigma Machine" supports the claim that German soldiers accidentally helped the Allies figure out the Enigma codes? With the right settings, the recipient only needed to type in the encrypted text and the message would light up in plain text. To use the Enigma machine, an operator typed a message into the machine, which would be scrambled by three rotors. . .
