The high-concept and space look of this super yacht is fabulous. The shape has been specially developed to cut through waves as it glides across the seas. It took many years to build Adastra including two years of planning and design. It is 42.5 meters long, 16 meters wide and weighs 52 tons.

"The challenge of turning this concept into a luxury yacht has taken us to further research and to develop new thinking on stability and comfort at sea for this type of craft." Mr Shuttleworth told reporters.

Its enormous petrol tank and dynamic sailing efficiency allows the Adastra to travel up to 4,000 miles without refueling. This is the same distance from London to New York. Adastra is powered by one Caterpillar C18 engine of 1150hp at 2300-rpm and has 2 Yanmar 110hp at 3200-rpm outrigger engines.

The hull of the Adastra is built from glass and fiber and can hold nine guests and six crewmen. The deck saloon has a panoramic view while the open cockpit has sofas on both sides. The open deck also has a door that hinges out to create a bathing platform. The main helm station, which has seating for two, is positioned in a raised pilothouse situated between the rear deck and the saloon area and forms part of the crossbeam structure.

According to boat international magazine, Adastra could spell the future for efficient long range cruising. It is one of the world's most amazing super yachts.
