The apparent wind on-board is often quoted as a speed measured by a masthead transducer containing an anemometer and wind vane that measures wind speed in knots and wind direction in degrees relative to the heading of the boat. Modern instrumentation can calculate the true wind velocity when the apparent wind and boat velocity are input.

Famous quotes containing the words apparent and/or wind:
“If we ever feel discouraged by the apparent constraints on humanity, about its lack of elbowroom and freedom of action, we should think of the Jews and the Greeks, insignificant, powerless, and tiny in the age of the dinosaur empires, yet providing the growing points for the next stage in human destiny.”
—Barbara Ward (1914–1981)
“The wind goeth toward the south, and turneth about unto the north; it whirleth about continually, and the wind returneth again according to his circuits.”
—Bible: Hebrew Ecclesiastes 1:6.
