Why was the passage of the Navigation Act of 1651 considered to be a problem for the colonies?

The Navigation Act of 1651 was problematic for the American colonies because it restricted their trade to only English ships, limiting their economic freedom and forcing them to rely on England for shipping their goods. This legislation aimed to bolster England's mercantilist policies by ensuring that colonial trade benefited the mother country, but it stifled the colonies' ability to trade with other nations. As a result, many colonists resented the restrictions, which contributed to growing tensions between the colonies and England.
