AMSICORA and BONARIA have been returned to owner Grimaldi

Ro-pax ferries AMSICORA and BONARIA are to be returned to owner Grimaldi after having been chartered by Tirrenia for the Naples-Cagliari route.
After refit, repainting and renaming (probably with the ‘cruise’ prefix) the vessels are going to be used on the Civitavecchia-Olbia route for Grimaldi Lines.
To the dissatisfaction of some local politicians, the ferries are being replaced by the 40-year-old veterans MOBY CORSE and MOBY DADA, as reported by SardiniaPost (in Italian).
Our remark: is it possibly a strategic move?
