In 2013, "Azzam" was the world’s largest yacht at 180 m long. According to rumors, the luxurious yacht’s owner is Khalifa bin Zayed Al Nahyan, the President of the United Arab Emirates. There’s a helicopter and submarines onboard, the yacht is served by 500 people, and it’s filled with enough fuel to take a round-the-world trip without entering a port. By the way, the President himself is living large, and he’s famous for big gestures: when he was elected, he raised the salaries of all citizens by 100%.
