Designed by Sussex-based yacht designer John Shuttleworth, the Adastra is so high-tech, it can even be controlled remotely at the touch of an iPad… as long as you don’t get any further away than 50 meters. Described as âone of the world’s most amazing super yachtsâ, Adastra is 42.5 meters long, 16 meters wide and weighs 52 tons. Maximum speed reached by the yacht is 22.5 knots and her range is an astonishing 4000 nautical miles at 17 knots. That is enough for a trip from the UK to New York without refueling. The hull of the Adastra is built from glass and Kevlar and can house nine guests and six crewmen. Inside living areas are equivalent to that of luxury four-star hotels, with full kitchen, bath and bedroom spaces. With her shiny body and high-tech design, this super yacht looks like something can ship in space. [source]
