Thanks for your input.

We have put our anchor far away from the grass parts. Very good holding. Hope the same is the case for the other boats here in the bights.

In the last two Hours we had two squalls bringing gusts up to 28 kts and everything was fine.

Does anybody know if it is a front where the squall came from. In the satellit images I could only see a chain of clouds looking like a moderate front but didn‘t see a warm/cold front in the forecast charts.
