Enigma is one of the world's largest private superyachts. Believed owned by Aidan Barclay, son of the British media tycoon David Barclay. Enigma was sold after her former owner, Larry Ellison, took delivery of Rising Sun, the 6th 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, the yacht is renowned for her design and agility that enables a maximum speed of 28 knots, although some sources quote 30 knots. Accomodation includes 9 luxurious suites.
She was built by German shipyards Blohm & Voss and powered by two Deutz AG BV16M628 diesel engines each producing 5,000 horsepower plus one LM1600 gas turbine producing 18,500 horsepower.
