This is Russian billionaire Roman Abramovich’s mega-yacht Eclipse
The 557-foot Eclipse comes with features including two helipads, a submarine, multiple hot tubs, a pool and a missile-detection system. It has “two swimming pools — the larger of which converts into a dance floor when drained — bullet-proof glass, 6ft home cinema screens in every guest cabin and a master cabin where the roof opens to allow Abramovich and his girlfriend Daria Zhukova to sleep under the stars. An anti-paparazzi electronic “shield” will take care of their privacy while on board.”
It is the largest private yacht in the world, beating the 532-foot yacht Dubai, owned by Sheikh Mohammed bin Rashid al-Maktoum, and is Abramovich’s 5th yacht, although he sold one and gave another to his ex-wife.
