11 Fascinating Facts About ‘Planet Nine,’ a 240-Foot Superyacht With a Subterranean Cinema

Planet Nine is built for long-range cruising and epic heli-skiing adventures. As such, the 240-foot yacht, owned by billionaire financier Nathaniel “Nat” Rothschild, began life at commercial shipyard Cantiere San Marco in La Spezia, with the purpose of gaining an all-weather hull. Following a legal dispute, Project Nato, as it was then known, was moved to Admiral Yachts in 2016 where the build was completed.

The yacht’s trademark wing stations and mast structures, penned by Tim Heywood, are balanced by a super-sized helipad on the aft deck, which doubles as a basketball court. A forward jacuzzi and bank of sun pads on the sundeck is where guests gather when cruising into port.

Built for more than just posing however, the yacht’s credentials include a range of more than 6,000 nautical miles when cruising at 14 knots. Planet Nine can carry 340,000 liters of fuel, 9,000 liters of aviation fuel for the helicopter, and 40,000 liters of freshwater with the capability of making an additional 18,000 liters per day. How many liters of wine from the Rothschilds’ top Bordeaux estates are kept on board remains a mystery.
