The floating office of one of the richest men in the world has been at anchor in front of Dubrovnik for the past few days. The superyacht Aviva, which at 100 metres long and with the capacity for 16 guests, is the property of UK businessman and owner of Tottenham Hotspur FC, Joseph C. "Joe" Lewis. With her vivid colours and striking lines the Aviva has certainly been grabbing people’s attention.
