Classicly

When Great Britain attempted to reduce to obedience the rebellious colonies which were to form the United States of America she was dealing with a people who in the North at least had long been conversant with the building and sailing of ships. A New England built ship entered the Thames in 1638, only eighteen years after the landing of the Pilgrims at Plymouth, Massachusetts. The New England men, with a sterile coast, with limitless fishing grounds and unsurpassed harbors, turned as naturally to the sea for livelihood as did the South, more kindly treated by nature, to agriculture. In 1670 it was estimated that two thirds of the British shipping was employed in the American trade.
