Must be the famous Arquipelago, I guess. As far as I know, Luerssen is based in Bremen, Germany which is not really round the corner. Maybe the superowners of the superyachts have found out that there is an alternative to the côte d'azure...and a very nice one as well!
Haven't been to the islands in the archiepalgo but will definitely try it next summer...albeit on a smaller boat, probably...
