"The worst kept secret on the marina." A mysterious nine-figure superyacht sailed into a Los Angeles marina with its name concealed, but locals apparently didn’t need long to identify the famous owner behind the massive vessel. The yacht, which has been docked in Marina del Rey, reportedly belongs to “Harry Potter” author J.K. Rowling and its name was reportedly covered soon after docking. Superyacht broker Chris Cecil-Wright told Fox News Digital owners will sometimes take steps to make their vessels less easily identifiable, although he said concealing a yacht's name is "very rare." "Particularly when you're a recognizable face or name, it becomes increasingly difficult to be able to relax anywhere in public," he added.
