Log your sessions; that is how Windulu gets to know you.
The advice is a tool. You remain responsible for your own safety.
Kitesurfing on the Grevelingen only at Grevelingendam-Noord; not allowed here. Wing and windsurfing are allowed, except in closed breeding-bird zones (check the Rijkswaterstaat map).
The open water at Grevelingen (Scharendijke/Den Osse) faces NNW (335°). The safest wind directions to wing foil here are north, northeast, west and northwest (onshore or cross-onshore). With the wind from the east, southeast, south and southwest, it runs cross to cross-offshore: doable, but mind your position and don't go alone.
