Your vessel is at the approaches to Savannah, GA, with the wind coming out of the west. What will be the approximate direction of the wind-driven current?

Correct Answer: Option A — 080°

Ekman spiral principles dictate that wind-driven surface currents set approximately 20 to 45 degrees to the right of the wind direction in the Northern Hemisphere. A west wind blowing from 270 degrees drives surface water toward 080 degrees true.
