One of the first thing you should learn during your first kitesurf course is the wind window.
The wind window is the entire zone where the kite can fly, is always downwind to you, and his width depends by the lenght of the lines (shorter lines= smaller wind window).
Keep always your wind window clean from every danger or obstacles (as we explained in the S.e.a. assessment)!!
The wind window is made mainly by 2 zones: the edge (or neutral zone) and the power zone.
