This vessel is the new 80-meter-plus "U-81" which used to be a 76.6-meter offshore supply vessel named "FS Cygnus" was converted into a yacht support vessel. Given it is painted in the same manner and is also called "U-81" we can safely assume it is the support vessel for "Ulysses". The vessel has now been delivered and was last known to be heading to Gibraltar. Photo by Lichting98.nl
