Russian billionaire Andrey Igorevich Melnichenko has had a mega yacht built for him, and mega it definitely is! This £260m beast is 300ft tall and boasts 8 floors and even an underwater observation room. reports that the boat, simply named ‘A’, is powered by a ‘hybrid diesel-electric package with controllable pitch propellers,’ and is designed to accommodate 20 guests and a crew of 54. The cruise speed of the ship is 18mph, with a top speed of 24mph. The hull is made of steel, with a teak-finish deck.

Part of the appeal of the extreme size of it is the fact it will swamp any other yacht that comes near it. Not only is it extreme in the world of yachts, it also pretty big compared to everything else!
