Meet Superyacht Adastra, your floating multi million dollar home that can efficiently cross both the Atlantic and Pacific ocean at high speeds.

The striking 42.5m trimaran Adastra was launched in China on 11th April 2012. She is the result of meticulous attention to detail and innovative design to create a yacht that meets the needs of a very experienced ocean voyaging couple and their family, and to provide the level of comfort and style expected in a yacht of this class and size.

The team at Shuttleworth Designs aimed to set the standard for low fuel consumption in large fast moving ocean going yachts. In order to achieve the light weight required for very low fuel consumption. The deck and superstructure of the Adastra was constructed from carbon fibre with Nomex honeycomb core, the hull is glass/kevlar foam sandwich and the interior is lightweight 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.

Measurements taken during the sea trials show that her 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 10,000nm starting with 30,000 litres of fuel.

This achievement by the Shuttleworth team has won them The Superyacht World Showboats award for naval architecture with Boat International stating, “this yacht will have the best performance in the most sea states of all those presented.”
