Bolded Info:The Navigation Laws were the most famous of the laws to enforce mercantilism. The first of these was enacted in 1650, and was aimed at rival Dutch shippers who were elbowing their way into the American carrying trade. The Navigation Laws restricted commerce from the colonies to England (and back) to only English ships, and none other.
However colonists did agree that Parliament had the power to enact measures to benefit trade but not to legislate and internal American tax. External taxes, such as the Sugar Act, Navigation Acts or Molasses Act had all been accepted as tax affecting trade, a simple import duty.
