"Adastra" 42.5m TrimaranStability, Luxury & Efficiency in Hi-Tech Harmony Move over 'EarthRace'. Step aside 'Cable & Wireless'. There's a new trimaran in town and it's set to pierce the luxury yachting industry. Enter "Adastra", currently under construction at McConaghy Boats in China, this one-off trimaran designed by John Shuttleworth is being built for a Hong Kong client with interstellar voyages in mind. “Adastra” is the result of more than 5 years of design 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 to further research and to develop new thinking on stability and comfort at sea for this type of craft.
