The Founding of Longtitude

John Harrison was the son of a carpenter, and Harrison was a carpenter too, ships were trying to find the secret of how to be able to know how far away they were from their dock, so, if it was noon at the dock, and 2:00, they were 30 degrees away from the dock, because, every 24 hours Earth spins 360 degrees, every hour it moves 15 degrees. When Harrison was 21, the Longitude Prize was announced, whoever had the most successful way too count longitude would win 10,000,000, or ten million, when the Prize was announced, Harrison instantly wanted to compete in it, so he build a "sea clock" known as H1. When H1 failed, he build a new clock, H2, H2 didn't take up as much space as H1, but it was heavier. H2 was made, but in a war, and it was too important to go out sea, but Harrison found a flaw in H2, and stopped all work, Harrison then made H3, it performed very well, but not enough, then, for many years, he build H4, but he was too old to go on a voyage to test it, so his son, William Harrison, did it, and H4 won the prize, but, there was no official winner of the Longitude Prize.
