There's being wealthy and then there's being so filthy f*cking rich, you build an entire mansion that could house a small village on the ocean, say it's a sailboat and call it a day.
Russian billionaire Andrey Igorevich Melnichenko (uh, let's just call him Andrey) now owns the world's largest yacht because he apparently had $462,000,000 bucks to spare. And it's not like he was really needing one because this yacht is actually an upgrade to his previous yacht which cost $294,000,000. Long story short, you can take your pontoon boat and get the hell out of here with that noise.
With something this big, my question is why even own a boat if you can barely find the edge of it in order to see water. Might as well just build a moat around your house.
The yacht has just a few decks, only EIGHT in total with an observation room below sea level on the bottom floor in case you want to see your enemies sink to the bottom because only super villains have boats like this. I'm sure Andrey is a good guy and deserves all of his riches but even Bruce Wayne didn't have a boat like this.
How is Andrey so damn rich? He founded four different mega-companies, two of which manufacture fertilizer and coal, but also started a power generator company and a pipe exporter company. He's also the 97th wealthiest person on the planet, named by Forbes magazine.
And if all of that isn't enough to keep him busy, he's also married to a former Serbian model, y'know, if you're into that sort of thing.
As for the rest of us, we'll just have to settle for sitting in a bathtub.
