4. J.K. ROWLING – AMPHITRITE YACHT, ESTIMATED $28 MILLION
The super lavish Amphitrite can easily be compared to a product of someone’s dream. The 5-cabin luxury yacht has been bought by J. K. Rowling from former owner Johnny Depp. Depp had previously furnished the boat with extravagant accommodation for ten people including video games, a satellite TV, a home cinema and even water sports equipment. However, Rowling has recently put the yacht up for sale.
