Photos: Inside The World's Biggest Yatch, N50 Billion Worth

 This is the world’s biggest built by South African construction gurus Oceanco and designed by Australian Sam Sorgiovanni, the 88.5 metre-long yacht has a remarkable pedigree history.

With a repertoire to rival the most outlandish Saudi and Russian mega-yachts, the Nirvana is causing a bidding war among billionaire sailors as they battle to snap up the £200 million (N49,463,088,884) sea city.
Only a handful of yachts have been priced more than the one-year-old vessel – making it one of the most luxurious floating mansions on the planet.

 All guests cabins are situated on the main deck, with floor to ceiling windows and as well as the full beam VIP stateroom.

The silver engraved elevator services all decks and leads guests up to the owner’s deck which can be transformed into a secluded on-board retreat.

The owner’s stateroom dominates over half of the upper deck, with a private sunbathing area with Jacuzzi forward, salon with terraces over the sea and a covered dining area.

Exterior stairs on the above deck lead to the bridge deck and the enormous and superbly equipped gymnasium and spa.
But when spas and five-star dining becomes too much, there is a private sundeck with plunge pool to enjoy, a 3D cinema next to twins garages that caters for supercars, ski boats or 10 jet skis.

Or if riding waves is too similar to sailing, then owners will be able to fly off in their own helicopter from their private helipad.
