20. Sailing Alone Around The World
He is primarily regarded as the first man to traverse the world alone in his sailboat single-handedly. On June 21, 1892, he relaunched the boat named The Spray, which he spent the last year rebuilding. Then, on April 24, 1895, Captain Slocum left the safe harbor at Boston, Massachusetts. Eventually, he found his way to Gibraltar, then to Brazil. From there, this explorer had to wait 40 days to enter the Pacific Ocean due to storms. Soon then, he found his way to Australia, crossed the Indian Ocean, and headed for home.
