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
Speed of the Wind driver. During testing, the car appears to have run, although not competitively, at either Brooklands or Montlhery. Speed of the Wind was built for long-duration speed records, which were the domain of Ab Jenkins and the Bonneville salt flats of Utah. Jenkins was fond of competition and was instrumental in encouraging British teams to travel to Bonneville. In September 1935, shortly after Campbell's 300 mph record with Blue Bird, Eyston broke Jenkins' 24-hour record and raised it to For the 1936 season, Jenkins created the Mormon Meteor by fitting a Curtiss Conqueror V12 into his previous Duesenberg chassis. Eyston returned,
