At $14.5 million Adastra is the world’s most amazing yachts
Trimaran Adastra, designed by John Shuttleworth, has recently been launched in China for a Hong Kong clients Anto and Elaine Marden.
“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.
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.
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 second 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.
