Another designer on the list is Diane von Fürstenberg, who was once married to Prince Egon von Fürstenberg. Since their split, she has since been in another relationship with a very well-known television executive and media mogul, Barry Diller, who now own one of the most popular yachts showcased online named Esos. The 305-foot mega yacht has a 200-foot high mast and is worth over $150 million. The ship is so popular in fact, that it has it’s very own Wikipedia page.
