NAVIGATION ACTS The NAVIGATION ACTS were a series of laws passed to apply mercantilist policy to the American colonies. The purpose was to make sure American trade centered on England. 1. Only English or colonial merchants and ships could engage in trade in the colonies. (1651) 2. Certain valuable American products could be sold only in the mother country. These ENUMERATED GOODS were wool, sugar, tobacco, indigo, ginger, dyes. Later acts added naval stores, copper, and furs. (1660) 3. All foreign goods destined for the colonies had to be shipped via England and were subject to English import duties. (1663) 4. A fourth provision was added to the original three later. The colonies could not make or export items that competed with English products. (1673) 5. In 1696 Parliament enacted another Navigation Act which established VICE-ADMIRALTY COURTS in America. These courts were to deal with the smuggling cases at which local courts and juries tended to wink 6. Also in 1696, England created a 15-member BOARD OF TRADE AND PLANTATIONS to deal with the economy of the American colonies. It gathered information, reviewed Crown appointments in America, studied legislation passed by colonial legislatures, supervised trade policies, and advised the monarchy on colonial affairs. It had no direct powers of enforcement.
