Final answer:
On a sailing trip from the United States to Europe, you would want to be in the area of the Westerlies, as they are the prevailing winds that assist in eastward travel across the Atlantic.
Step-by-step explanation:
If you were on a sailing ship going from the United States to Europe, you would want to be in the area of the Westerlies. The Westerlies are the prevailing wind patterns that flow from the west to the east in the middle latitudes between 30 and 60 degrees latitude. They are responsible for carrying ships across the Atlantic and were especially important during the age of sail for transatlantic voyages. The Doldrums, or the Intertropical Convergence Zone (ITCZ), is known for its calm winds and wouldn't be favorable for sailing. Trade winds blow predominantly from the northeast in the Northern Hemisphere and wouldn't directly assist in a journey from the US to Europe. The Polar cell influences regions near the poles and would not be beneficial for transatlantic travel.
