How is true wind angle calculated? – ShortInformer

In sailing, apparent wind is the speed and direction of wind indicated by a wind instrument (anemometer) on a moving craft (on water, land or ice) in undisturbed air. It is composed of the combined speeds and directions of the craft and wind observed by a stationary wind instrument—the true wind. A true wind coming from the bow increases the apparent wind induced by the speed of the craft, coming from the stern it decreases apparent wind, and coming from th… WebIf you are using a wind meter you can estimate the true wind speed by sailing close hauled and subtracting 80% of the boat speed from the apparent wind reading of the wind meter. That will get you very close. For example, if the apparent wind is 20 knots and the boat is going 6.2 knots at 45 degrees to the true wind then the true wind is 20 - 6 ... in what habitats are sponges found
