Adastra is the 140foot (42.5m) Trimaran recently lanched in China, and was built at McConaghy Boats Zhuhai Facility, China for a Hong Kong client for long range ocean voyaging. Designed by John Shuttleworth Design. 

“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.  All this has resulted in the exceptional vessel that was recently launched by McConaghy boats in Zhuhai, China.

Adastra's 16 metre beam creates a spacious saloon 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 saloon window gives easy access to a large sunbed on the foredeck. The aft deck has a sofa and bar area to port and a dining area to starboard, further aft of this there is 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.  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.  The main helm station, which has seating for two, is positioned in a raised pilot house situated between the aft deck and the saloon area and forms part of the cross beam structure. 

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.

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.

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 fibre hatches, portlights, ladders and even hinges, which are all built specifically for the vessel.

John Shuttleworth begin_of_the_skype_highlighting end_of_the_skype_highlightingYacht 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.
