Water has been one of the main means of travel, transport, and trade throughout history. The ancient Greeks used boats for trade and for war. Ships have carried merchants and immigrants from one port to another. Even today, most products destined for sale overseas are transported by water. Ships and Submarines provides a detailed look at the technical development of these vessels and their important role in history. Illustrations accompany the engaging narrative, and a timeline, glossary, further reading list, and index provide easy access to the broad range of information contained within the book's pages.
