Was hoping that it was enough for foil, but wind was pretty strong. When I arrived I saw the big boats (Skûtsjes) were racing and one of them was blown over on it's side. That meant easily enough wind for slalom. Later I took some buoys of the Skûtsje race which made up for a perfect downwind slalom course. Also I made an upwind trip towards the abandoned Skûtsje which was still on it's side, just laying there.
