140ft Superyacht Adastra

 Adastra is an impressive 140-foot cruising trimaran designed by Shuttleworth and built by the McConaghy yard in China.

Ordered by an enthusiast living in Hong Kong, this motor trimaran is being built like a genuine racing boat, and weight reduction has been drastic, to offer a cruising speed of 17 knots and a range of 6500 km on a full tank, an average of 120 litres/hour (and only 90 l/h at 13 knots)… Propelled by an 1150hp engine, the machine’s top speed will be 22.5 knots. However, this is a real cruising boat, whose accommodation will have you dreaming. Awesome!
