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.
Letter Idea That I Made for an Automatic Irrigation System, via Arduino:
Dear (<u>The Person The Letter Is For</u>),
I have noticed that many of my plants die due to neglect. People (including me) don't water their plants. This problem effected me and most-likely lots of others very much because we have put in lots of my time and money into making a garden, just for it to fail. In fact, the Ancient Civilization of Egypt collapsed because the Egyptians were not able to properly maintain water levels in plants, leading the plants to wilt, a lack in water because of wasting the water on the plant, the Egyptians to die of dehydration, and the fall of Ancient Egypt. So I made an Arduino-based automatic irrigation system to help other like me and obviously myself maintain a healthy garden. This device will water my plants whenever they are dehydrated, and it will water in correct amounts, due to the soil moisture sensor in the setup. This solution worked, and I feel happy because the solution worked, it was very inexpensive, and it was super easy to make.
Sincerely,
<u>(You)</u>
