Got it fixed.
I went through all sceneries installed and saw 1 of a VA for which I fly and who have some small add-ons for the areas they created a tour for. They have 2 versions (default or Orbx), but both of them created the "tsunami" ship. I'll contact the guy who made it.
For the rest there should be no contaminations in my installed sceneries anymore...
Sorry to have bothered you, but it was a spectacular view, wasn't it?
Cheers
Marcel
