Apparent wind 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 speed and direction are input. In sailboat racing, and especially in speed sailing, apparent wind is a vital factor, when determining the points of sail a sailboat can effectively travel in. A vessel traveling at increasing speed relative to the "prevailing wind" will encounter the wind driving the sail at a decreasing angle and increasing velocity. Eventually, the increased drag and diminished degree of efficiency of a sail
Wind power in Morocco Wind power in Morocco In terms of wind power development, Morocco enjoys quite favourable wind resource patterns, both in the northern part of the country near Tanger and to the west where certain regions benefit from regular trade winds. In 2013, 5,05% of electricity produced in Morocco was coming from wind power. Wind power could be a major contributor in the electricity sector of Morocco. According to data presented by minister Amara in Madrid in 2015, the country’s onshore potential is estimated at 25 GW, of which 6 GW could be installed by 2030. The average wind speed is 5.3
