Enigma formerly ECO and Katana is one of the world's largest private superyachts. According to Power and Motoryacht magazine, she is owned by Aidan Barclay, son of the British media tycoon David Barclay who recently purchased the Telegraph newspaper. Barclay then rechristened her Enigma. She was sold after her former owner, Larry Ellison, took delivery of Rising Sun, the second largest private yacht in the world. Measuring slightly more than 244 feet (or around 75 metres), Enigma was launched in 1991 and originally christened ECO by its former owner, Mexican mogul Emilio Azcárraga, founder and former CEO of TV and media conglomerate Televisa. Enigma is renowned for her design, including a pyramid-like superstructure surrounded by convex windows, and an agile design that enables her to achieve a maximum speed of 28 knots, although some sources quote 30 knots as her top speed. She was built by German shipyards Blohm & Voss.
