SIROCCO runs to 47 metres, taking twelve guests across six cabins with a crew of nine. Built in 2006 and based out of Monaco for charter, she sits in the agile middle ground — substantial enough for the open western Mediterranean, nimble enough to tuck into Villefranche or thread the calanques of the Estérel. A weekend in Portofino, an afternoon off Cannes, all comfortably within range.
