The shipping costs would have been massively reduced by the employment of foreign ships to carry the cargoes.

How do you know?

This was prohibited in the Union because of the "Navigation Act of 1817.".

Complete nonsense. The Navigation Act prevented foreign ships from carrying cargo from one U.S. port to another. It did not prevent them from calling at Charleston, loading with cotton, and taking it to the United Kingdom.
