We Are One: Most ships used well-established routes to cross the North Atlantic during the colonial period. However, few contemporary maps depict specific voyages. This 1771 chart delineates several general routes, such as the "usual course to the West Indies, Carolinas & Virginia for sake of the Trade Winds and Currents." Contrast these with the ones represented on the map of colonial shipping routes compiled in 2013, which was based on specific voyages documented in ships' logbooks. For example, the 1771 map shows ships landing in Boston, New York, and Charleston, while the modern one notes that ships arrived all along the coast of the North American colonies.
