Debuting at the Monaco Yacht Show, Mercedes unveils the final design of its ARROW460 Granturismo yacht. Built by UK-based Silver Arrows Marine, the boat is a stunning interpretation of the company's current design language that measures 46 feet in length with long and lean lines and a raked roofline like that of a CLS sport sedan. No word on what's powering the boat, but we can imagine it's got enough thrust under the hood to make AMG proud.
