What do you do when you’re worth over $8billion? You spend $450million on a luxury super yacht. Russian businessman Andrey Melnichenko has built the world’s largest sailing yacht -which boasts of eight decks, a glass observation area, measures a roomy 468 feet and weighs 14,224 tons. The ship will have a crew of around 54 people, the masts are very tall, and its sails are bigger than a football field when all are flying. It will be the largest privately owned sailing yacht in the world.
