Roman Abramovich is the Russian oligarch who once owned Justin Bieber’s yacht, Ecstasea. Now, Abramovich has moved on to a new yacht, Eclipse. Eclipse, which cost half a billion to make, launched in 2009 and officially hit the seas in 2010. Eclipse has many impressive amenities, including twenty-four guest cabins, hot tubs, a disco hall, two pools, three launch boats, and a submarine.

It takes a whopping seventy crew members to keep Eclipse in gear. Another cool feature is the ship’s advanced security system. Abramovich also has a missile detection system installed in the Eclipse.
