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:
“To understand
The signs that stars compose, we need depend
Only on stars that are entirely there
And the apparent space between them. There
Never need be lines between them, puzzling
Our sense of what is what.”
—John Hollander (b. 1929)
“They went to him and woke him up, shouting, “Master, Master, we are perishing!” And he woke up and rebuked the wind and the raging waves; they ceased, and there was a calm. He said to them, “Where is your faith?” They were afraid and amazed, and said to one another, “Who then is this, that he commands even the winds and the water, and they obey him?””
—Bible: New Testament, Luke 8:24-25.
