, the particular routes were also shaped by the powerful influence of
winds and currents. For example, from the main trading nations of Western Europe, it was much easier to sail westwards after first going south of
30° N latitude and reaching the so-called "
trade winds", thus arriving in the Caribbean rather than going straight west to the
North American mainland. Returning from North America, it was easiest to follow the

) from plantations in the Caribbean and shipped it to New England and Europe, where it was sold to distillery companies that produced rum. Merchant capitalists used cash from the sale of sugar to purchase rum, furs, and lumber in New England which their crews shipped to Europe. With the profits from the European sales, merchants purchased Europe's manufactured goods, including tools and weapons and on the next leg, shipped those manufactured goods, along with the American sugar and rum, to West Africa where they bartered the goods for slaves seized by local potentates. The crews then transported the slaves to the Caribbean and sold them to sugar plantation owners. The cash from the sale of slaves in Brazil, the Caribbean islands, and the American South used to buy more raw materials, restarting the cycle. The full triangle trip took a calendar year on average, according to historian Clifford Shipton.

and
hemp. The ship then returned to Europe to complete the triangle.
The triangle route was not generally followed by individual ships. Slave ships were built to carry large numbers of people, rather than cargo, and variations in the duration of the Atlantic crossing meant that they often arrived in the Americas out-of-season. Slave ships thus often returned to their home port carrying whatever goods were readily available in the Americas but with a large part or all of their capacity with ballast.
Cash crops were transported mainly by a separate fleet which only sailed from Europe to the Americas and back. In his books,
Herbert S. Klein has argued that in many fields (cost of trade, ways of transport, mortality levels, earnings and benefits of trade for the Europeans and the "so-called triangular trade"), the non-scientific literature portrays a situation which the contemporary historiography refuted a long time ago.
A 2017 study provides evidence for the hypothesis that the export of gunpowder to Africa increased the transatlantic slave trade: "A one percent increase in gunpowder set in motion a 5-year gun-slave cycle that increased slave exports by an average of 50%, and the impact continued to grow over time."
New England

. Yet, the "triangle trade" as considered in relation to New England was a piecemeal operation. No New England traders are known to have completed a sequential circuit of the full triangle, which took a calendar year on average, according to historian Clifford Shipton.
The concept of the New England Triangular trade was first suggested, inconclusively, in an 1866 book by George H. Moore, was picked up in 1872 by historian George C. Mason, and reached full consideration from a lecture in 1887 by American businessman and historian William B. Weeden.
