J.K. Rowling's mega yacht, named Samsara, recently caused a stir in the U.S. as it made stops in Florida, Georgia, and South Carolina. The luxurious vessel, built in 2015 by Oceanco, boasts seven cabins for guests and 13 cabins for crew members. With a jaw-dropping price tag of $150 million and an annual operation cost of $10-15 million, the yacht offers amenities like a movie theater, swimming pool, gym, and more. Available for charter at $1,179,000 per week, Samsara also features an array of water toys for guests to enjoy. Rowling, known as the world's wealthiest author with a net worth of $1 billion, has found immense success with the "Harry Potter" franchise, selling over 600 million books and earning billions from the film adaptations. Despite her immense wealth, Rowling's philanthropy once led to her removal from Forbes' billionaire list in 2012.
