The buyer has a long history of chartering 'some of the largest and highest quality charter yachts in the world', according to Moran Yacht & Ship, which is managing the build and brought the buyer.
This experience meant the owner had a big hand in the family orientated design, according to Moran, from the layout of guest accommodation to engine choice.
The superyacht, designed inside and out by Winch, features two helicopter pads, a 12 metre swimming pool, a resort style spa and staircases 'that to date have only been seen in palaces'.
A massive private owner's deck will provide sanctuary, with up to 22 guests accommodated in a further 11 staterooms.
'This project will be the largest yacht to date that Moran has built at Lurssen,' said company president Rob Moran. 'We area excited to be involved in such a great product with such a fantastic team.'
