Designed by John Shuttleworth, Adastra was created to meet the needs of a very experienced ocean voyaging couple and their family, who wanted to provide the level of comfort and style that would be expected in a yacht of this class and size.
The beautiful superyacht has an exceptionally low fuel consumption and yet boasts excellent sea keeping qualities and luxurious accommodation.
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 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 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 swim platform.
Below deck, extra space was created 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 in total and up to six crew members.
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 three 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 yacht’s superstructure is constructed from carbon fibre with Nomex honeycomb core, the hull is Glass/Kevlar foam sandwich and the interior features lightweight 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.
Adastra takes the power trimaran concept further than has ever been attempted before. The challenge of turning this concept into a viable luxury yacht led us to further research on stability and comfort at sea for this type of craft. Extensive tank testing and radio controlled model tests in waves were carried out to analyze stability and performance. Outrigger height was optimized for ease of motion at sea, and a new outrigger shape was developed to increase stability in waves. We undertook 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.
Today, Adastra remains one of the most iconic superyachts on the water.
