The yard has kept the yacht strictly under wraps at the wishes of her owners, who stipulated the desire for a full year's private cruising without publicity.
Interest in the yacht has been strong however, evident in a time-lapse video of Lonian's construction, which received more than five million views on Feadship's YouTube channel. Now the yard has released the first images of the yacht.
On her adventures around the world, in which Lonian spends as much time away from marinas as possible, the yacht travels with a "flotilla" of toys and tenders, as well as a 66 metre support vessel, which transports more equipment and an additional crew of 22.
Lonian's exterior design, which is characterised by a deep blue hull, plentiful stainless steel and extensive glass, was penned by Sinot Exclusive Yacht Design.
“The result is a Feadship with the presence and stance of a beefy motoryacht wich simultaneously retains and elegant and slender air," the yard said.
A total of 22 openings from interior to exterior create an "unrivalled open feel on board," Feadship said.
One particularly dramatic feature is the swimming pool, the translucent bottom of which doubles as the ceiling of the beach club below. A cinema screen, not visible in these daytime shots, is also integrated into the edge of the pool.
The transom hatch meanwhile features a swim platform that opens and closes like the roof of a convertible car, with the teak hatch opening and aft door descending before the hatch closes again.
The large flush foredeck on the dedicated owner's deck features a Jacuzzi which can be heated and cooled to a range of temperatures between 10 and 38 degrees. This feature was specifically requested by the owners, who enjoy using the chilled plunge pool after working out in the bridge deck gym.
Lonian's helideck accommodates an AW169 helicopter and also features a crane capable of lifting 3.5 tonnes.
The interior of the yacht, which remains private, was created by Sinot in collaboration with Richard Hallberg Interior Design. While the interior has not been revealed, Feadship revealed that it contains a glass elevator serving all five decks and a main deck lounge with panoramic full beam views.
Accommodation on board is for a total of 14 guests in seven cabins, including the owner's stateroom, four large guest staterooms and two VIPs. The crew quarters meanwhile consists of 15 crew cabins and one captain's cabin.
