22. Eclipse – $1.5 billion
Russian billionaire Roman Abramovich is the owner of beautiful Eclipse, the second-most expensive yacht in the world. Assembled by Blohm+Voss, there are 24 cabins, two pools, several jacuzzies and a disco. There is even a mini-submarine, which you can use to go 50 meters deep. The yacht can detect intruders and has a missile defense system as a shield to keep Roman safe from paparazzi.
