Definition

The direction that the wind comes across the boat when the boat is moving; differs from the "real wind," which is the direction the wind is blowing across no-moving objects and surfaces. The true-wind is the apparent wind which you feel when you are not moving, for example at anchor. The apparent-wind is the wind direction and speed which you feel while the boat is moving. The apparent-wind is forward of the true-wind (except when it is directly forward or behind the boat). In a close reach, the apparent-wind is forward and is stronger than the true-wind. In a deep broad reach, the apparent-wind is forward and is weaker than the true-wind.
