Here's the latest plaything for the super-rich - a giant three-hulled yacht that cost £15million to make and would fit as comfortably in outer space as it would on the open sea.
Described by Boat International magazine as 'one of the world's most amazing super yachts', the 42.5metre-long Adastra is a floating pleasure palace equipped to entertain a billionaire with even the highest of standards.
She is the the new pet of Hong Kong-based shipping magnate Anto Marden, 64, and his wife Elaine, whose uses for her may include - among other things - gliding between the two tropical islands they already own off the coast of Indonesia.
Designed by Sussex-based yacht designer John Shuttleworth, the Adastra is so high-tech, it can even be controlled remotely at the touch of an iPad... as long as you don't get any further away than 50 metres.
The yacht's high-concept, space-age look is no gimmick. The shape has been specially developed to cut through waves as it glides across the high seas.
Adastra was unveiled in China and took three years to build, as well as two years of planning and design. It is 42.5 metres long, 16 metres wide and weighs 52 tons.
Her enormous petrol tank coupled with her dynamic sailing efficiency allows the Adastra to travel up to 4,000 miles without refuelling - the same distance from London to New York.
‘It takes the power trimaran concept further than has ever been attempted before,’ Mr Shuttleworth told Boat International.
‘The challenge of turning this concept into a viable luxury yacht has taken us to further research and to develop new thinking on stability and comfort at sea for this type of craft.’
It is the result of five years of planning and construction, and rivals anything owned by yacht-lover Roman Abramovich.
The hull of the Adastra is built from glass and Kevlar and can house nine guests and six crewmen. The deck saloon has a panoramic view while the open cockpit has sofas on both sides. The open deck running aft also has a door that hinges out to create a bathing platform.
Boat International magazine said Adastra 'could spell the future for efficient long range cruising'.
