Name: Amphitrite
Value: $19.2 million*

Once owned by Johnny Depp, Harry Potter mastermind J.K. Rowling bought the gorgeous Amphitrite for a staggering $27 million back in 2015. But with its cutting edge satellite system, 12-knot cruising speed, and multiple guest rooms most believe she paid far less than its actual value.

Rowling reportedly put the ship up for sale just a year after finalizing the purchase. With an asking price of about $19 million, prospective sailors can also charter this luxury vessel for roughly $130,000 a week. Adding that to what Rowling makes every day from her Comcast-owned “Wizarding World” section at Universal Studios makes her one insanely rich lady.

Rowling hasn’t been spotted out at sea in several months, most likely due to her latest writing efforts – including a new novel written under the pseudonym Robert Galbraith. She also runs and finances several philanthropic organizations that keep her relatively landlocked as of late.
