Adastra is the 140' (42.5m) Trimaran lanched in China, and built at McConaghy'S Zhuhai Facility, China for a Hong Kong client for long range ocean voyaging. Designed by John Shuttleworth Design.​​"One of the world's most amazing super yachts, that could spell the future for efficient long range cruising" Boat International “Adastra” is the result careful design, planning and discussion with the owners, to build 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 that would be expected in a yacht of this class and size. No effort has been spared in the challenge to produce a beautiful yacht that will have low fuel consumption and yet provide excellent sea keeping qualities and luxurious accommodation. “Adastra” takes the power trimaran concept further than has ever been attempted before, previous vessels like “Earthrace” and “Cable and Wireless” were stripped out record breaking machines. The challenge of turning this concept into a viable luxury yacht has led us to further research and to develop new thinking on stability and comfort at sea for this type of craft. Extensive tank testing and radio controlled model tests in waves have been carried out to analyze stability and performance. Outrigger height has been optimized for ease of motion at sea, and a new outrigger shape has been developed to increase stability in waves. We have undertaken a 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.
