25. Eddie Lampert’s Foutainhead
Investor billionaire Eddie Lampert likes to joke that the Fountainhead, a 288-foot yacht with 7 cabins, belongs to Mark Cuban. Mr. Lampert likes to keep his privacy and has not released any photos of the interior of the Fountainhead. All we can tell you is that it may be similar to its sister yacht, the Musashi which is owned by Larry Ellison (not much info on that either).
