The Saudi prince's $500 million yacht Serene was purchased to solve an unexpected problem: seasickness. In 2014, Prince Mohammed bin Salman bought the 134-meter superyacht after Bill Gates had rented it, but the prince had a unique request—a modest bedroom three decks below the owner's suite to cope with his seasickness.
The Serene: A Record-Breaking Superyacht
The Serene was built by Italian shipyard Fincantieri and launched in 2010. At 134 meters, it was the largest superyacht ever built in Italy at the time. Its first owner was Russian businessman Yuri Shefler, who commissioned the vessel.
The yacht gained fame when Bill Gates rented it for $5 million a week during a family vacation in the summer of 2014. Gates reportedly enjoyed it so much that he considered buying it, but the Saudi prince acted faster.

Why a Seasick Prince Bought a Superyacht
Prince Mohammed bin Salman's purchase was driven by a desire to enjoy yachting despite his seasickness. The solution was a discreet cabin located three decks below the main owner's suite, providing greater stability and reducing motion.

This request highlights how even the ultra-wealthy must adapt to personal challenges. The Serene's design includes advanced stabilization systems, but the prince's cabin offers an extra layer of comfort.
