Russian billionaire has upgraded his £190million superyacht for a new model - at a cost of £260million. Andrey Igorevich Melnichenko's 'Sailing Yacht A', simply named after its owner, is taking its test voyage in Kiel, northern Germany. This is the world's largest sailing superyacht as the Russian industrialist takes his quest to ruling the seas one step further. The vessel is an upgrade to the Russian billionaire's current multi-million pound 'Motor Yacht A', that set him back £190million. At 468ft in length, with ship masts nearing 300ft high, the 'mega-yacht,' has eight floors and includes an underwater observation room. Mr Melnichenko is expected to recover some of the costs by licensing the technology developed for the vessel for commercial applications. Melnichenko also owns a Boeing 737.
