Designers revealed that the Adastra can be controlled by via an on-board iPad running a customized application, providing the tablet is within a distance of 50m from the boat. Although details on this control were scarce at the time of going to press, the designer behind the boat, John Shuttleworth, told TabTimes that the iPad can control everything from 'steering to flicking switches'.

Shuttleworth revealed that Palladium Technologies is behind the app, with the Florida-based company having previously developed another iPad-based system (SiMON2) to control the alarms, horns, wipers, winches and even security cameras on the new CL 70 series yacht from Cheoy Lee Shipyards of China. The firm told TabTimes that the app for the Adastra is called "drive by iPad" iiCaptain and confirmed that it is customized to just one iPad on the ship. The firm chose not to disclose further details at this time.

The superyacht specifications are pretty impressive. The boat is 42.5m long, 16m wide and weighs 52 tons, while it can house nine guests and six crew members. The boat is powered by one 1,150BHP engine, with two further 110BHP engines helping the boat achieve a top speed of 22.5 knots (that’s around 26 miles an hour). On-board there are 15 double bedroom cabins - each equipped with their own bathrooms and 6ft-wide television, while visitors will also discover a sauna, a steam bath, a whirlpool and bar, lounge and dining areas.

Built for Hong-Kong based shipping millionaire Anto Marden, the boat is said to be able to travel 4,000 nautical miles without refuelling (that’s New York to London), although Marden will apparently only be using the boat to travel between his two islands off the coast of Indonesia.
