A new sailing cruise yacht, reportedly the world's largest, has been introduced, featuring a blend of luxury and green technology. The vessel, which has 54 suites and can accommodate 110 guests, has been named and delivered, although its maiden voyage has been marred by an incident in which it damaged a world war ii aircraft wreck. Details about the yacht, including its length, vary, with some reports describing it as 220 meters and others as 722 feet.
