  1. "Adastra" 42.5m Trimaran
    Stability, 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.
  2. The Superstructure is 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, virtually every aspect of the boat is custom built. This includes carbon fiber hatches, portlights, ladders and even hinges, which are all built specifically for the vessel. In this rendering, the main helm station, which has seating for two, is positioned in a raised pilot house situated between the aft deck and the salon area and forms part of the cross beam structure.
  3. A SiMON² integrated ships monitoring system monitors fuel, security, pump sensors, electrical, lights, etc. The vessel has a fully automated fuel management system which includes an Alfa Laval system for cleaning the fuel. 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.
  4. The engineers 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. All this has resulted in the exceptional vessel that efficiency and luxury. The aft deck has space for a 4.9 metre tender and directly below is a garage which can store a 3.1 metre tender. The garage door has been designed to fold out and create a large dive platform.
  5. The anchoring system is unique with 3 anchors all driven by carbon fibre drum winches run by hydraulics. The primary anchor is a custom 130kg Bruce style anchor that deploys out of the starboard wing. The bow anchor is 80kg and deploys out of the bow with a carbon fibre arm. The third anchor is 60kg which deploys out of the port wing and will be used as a stern anchor.
  6. The aft deck has a sofa and bar area to port and a dining area to starboard.
  7. Adastra's 16 metre beam creates a spacious salon area on the main deck which offers superb views through a panoramic window and accommodates a lounge area, dining table, and navigation station. A forward facing door through the salon window gives easy access to a large sunbed on the foredeck.
  8. Extra space has been created below deck by slightly flaring the central hull just above the waterline. This area has been split into two sections with a full-width master cabin located aft with access from the deck saloon, and two further guest cabins, accommodation for the crew, and the galley located forward of the engine compartment. Adastra offers comfortable accommodation for nine guests and up to six crew members.
  9. Adastra's interior, such as this master bath illustration, is a result of Jepsen Designs, a Hong Kong-based architectural and interior design Firm. Although not exclusively working on yacht interiors, Jepsen Designs has worked with clients, naval architects and boat yards around the world for the past 20 years. Projects have varied from the interior design of modern sailing and motor yachts to the restoration of classic motor launches to the conversion of Chinese wooden junks into high-class pleasure vessels and house boats.
  10. A raised settee in the galley makes optimum use of hull space. Whilst drawing from Scandinavian modern design principles fused with Eastern accents, the Jepsen Designs team has developed versatility in creating designs and styles to match unique client expectations. Years of sailing and racing experience within the team further bolsters Jepsen Design's understanding of the technical and functional challenges a naval project offers.

  12. DETAILS


    Adastra in build at McConaghy's yard in China. For more than 40 years McConaghy has been at involved in race yacht construction; leading the way in research and application of new materials and technologies to build some of the strongest, lightest – and most successful – racing yachts launched. With manufacturing basis in both Australia and China, McConaghy now deploys its talent and mastery of laminated construction techniques across a number of different divisions, extending the strong commercial platform that has allowed it to defy industry trends and continue to thrive.
  13. John Shuttleworth Yacht Designs Ltd. is based in West Sussex, England and has gained a reputation for designing fast, strong, and safe boats. In the 1980’s Shuttleworth’s design team developed the concept of “Integrated Structure,” resulting in boats that were lighter, stiffer, and stronger than any previous multihull designs. Their designs became consistent race winners, and several have broken and still hold some of the toughest long-distance ocean sailing records. Many of Shuttleworth’s racing and cruising multihulls have completed round the world voyages. They continue to develop and use this technology to design both sailing and power multihulls, where significant savings in fuel consumption and increased range can be achieved. Always working closely with their clients to achieve their wishes, Shuttleworth Designs have kept to their philosophy of “form follows function” which has resulted in a unique style that can be recognized by anyone who is familiar with their work.
  14. Richard Oliver of applied ASTA has worked closely with John Shuttleworth Yacht Design to assist with the structural design and has carried out a full finite element analysis of the hull and deck structure to ensure that the maximum strength could be achieved within the minimum weight.
