On July 4, 1789, a tariff law was the first substantive legislation passed by the new American government. But in addition to the new duties, it reduced by 10 percent or more the tariff paid for goods arriving only in American craft.

It also required domestic construction for American ship registry. Navigation acts in the same decade stipulated that foreign-built and foreign-owned vessels were taxed 50 cents per ton when entering U.S. ports, while U.S.-built and -owned ones paid only six cents per ton. Furthermore, the U.S. ones paid annually, while foreign ones paid upon every entry.

This effectively blocked off U.S. coastal trade to all but vessels built and owned in the United States.

The navigation act of 1817 made it official, providing “that no goods, wares, or merchandise shall be imported under penalty of forfeiture thereof, from one port in the United States to another port in the United States, in a vessel belonging wholly or in part to a subject of any foreign power.”

The point of all this was to protect and grow the shipping industry of New England, and it worked. By 1795, the combination of foreign complication and American protection put 92 percent of all imports and 86 percent of all exports in American-flag vessels. American ship owners’ annual earnings shot up between 1790 and 1807, from $5.9 million to $42.1 million.
