Vektor setting and laylines

[wraa]

There is some photos , and the photo with is the trough wind direction
wen you do some calculation also get 78 degreas and on the chart plotter the wind arrow is pointing at 62 degreas ... and my drift is 13 ca. so there is some thing wrong in the cal.

and can i have a email address so i can send a small video showing the lay lines and why we need a filter , wen sailing in big waves the sensor is jumping , making the reading unusable , boat can go from 2 to 8kn , but on my tri data display it ok and stable because there is a filter

kind regard
