Prince Henry lived in the fifteenth century. As a boy he became devoted to the sea, and he dedicated (devoted) himself" to improving the design of Ships and the methods or sailing them. In 1416, when he was twenty-two. Henry founded a school for mariners, to which he invited everyone who could help him —— Jewish astronomers, Italian and Spanish sailors, and Arab mathematicians and map makers who knew how to use the crude compass of the day and could improve it. Henry's goal was to design and equip vessels that would be capable of making long ocean voyages without having to hug (keep close to) the shore. The caravel carried more sail and was longer and slimmer than any ship then made, yet was tough enough to withstand gales at sea. He also developed the carrack, which was a slower ship, but one that was capable of carrying more cargo. To Prince Henry the world owes credit far development of craft that made oceanic exploration possible.
