Talk about extravagance. <br /> <br />An anonymous Malaysian businessman just spent $4.8 billion on a superyacht covered in platinum and gold, making it the most expensive yacht ever sold, according to Luxury Launches. <br /> <br />The boat, named the History Supreme, is the work of Stuart Hughes, a British purveyor of luxury gadgets. <br /> <br />It took three years to complete and is covered in 100,000 kilograms of precious metals, according to The Daily Mail. <br /> <br />The master bedroom is particularly lavish; it's adorned in platinum and has wall art made of meteoric stone and the bones of a Tyrannosaurus Rex.
