Answer: Great coastal piers
Step-by-step explanation:
In the colonies of New England (northern part of the 13 colonies) arises a thriving ship production. Favored by the abundance of New World wood and a fine port structure, come large quantities of ships that would be used in the so-called triangular trade. The triangular trade can be simply described as buying a cane and Antillean molasses, which would be turned into rum. The drink obtained easy markets in Africa, where it was taken by New England ships and usually traded for slaves.
These slaves were taken for sale on the Antilles' farms or in the southern colonies. After the sale, the ships returned to New England with more molasses and cane for rum production. It was a highly lucrative activity, among other reasons for ensuring that the ship was always loaded with products to sell elsewhere.
