Adastra, The Wonderful Superyacht by John Shuttleworth

superyacht-adastra-1Say hello to Adastra, a 42.5 metre luxury superyacht designed by UK based boat designer John Shuttleworth. Built in China by McConaghy Boats over a period of five years, this futuristic trimaran was conceived for Hong Kong businessman Anto Marden, for long range cruising. As you would expect, the yacht is equipped with all of the amenities a master cabin, two guest cabins, luxury bathrooms, sauna, whirlpool, a fully functional kitchen, and a huge deck for relaxing. It can also house up to 9 guests and 6 crew members. Valued at $15 million, Adastra is powered by one Caterpillar C18 engine of 1150hp at 2300 rpm and has 2 Yanmar 110hp @ 3200 rpm outrigger engines – fuel consumption at 10.5 knots is as low as 17 litres per hour when carrying 10% fuel and water. At cruising load (20 tonnes fuel and water) she uses just 25 litres per hour therefore on delivery trips her range is 10,000 miles starting with 30,000 litres of fuel.

The Shuttleworth design team writes:

“We have undertaken state of the art structural analysis of all the major components in the yacht in order to achieve the light weight required for very low fuel consumption. The deck and superstructure is constructed from carbon fibre with Nomex honeycomb core, the hull is glass/kevlar foam sandwich and the interior is light weight oak cabinetry using honeycomb panels. To help reduce weight further, virtually every aspect of the boat is custom built. This includes carbon fibre hatches, toilets, portlights and ladders, which are all built specifically for the vessel.

Aerodynamics and hydrodynamics above the water line were carefully considered as we developed the overall exterior shape and we kept the boat streamlined both for air and water passing over the structure. The smooth seamless, unbroken surfaces also help to reduce weight as the outer-skin forms part of the structure to absorb torsional loads.”

Adastra, received awards in three categories at the 2013 ShowBoats Design Awards.

Naval Architecture – Winner
Newcomer of the Year – Winner
Exterior Design and Styling – Judges’ Commendation
