The £360million super yacht belonging to Russian oligarch Andrey Melnichenko has been spotted sailing into Gibraltar.
Sailing Yacht A - which has eight floors, a helicopter pad, an underwater observation room and three spa pools - can be seen floating by a massive tanker, and still appears to dwarf the vessel.
The staggeringly huge vessel is 468ft long and has three 300ft masts that are taller than the Palace of Westminster's clock tower.
Melnichenko, 45, a Belarus-born industrialist thought to be worth about £11billion, had the boat dreamed up by renowned French designer Philippe Starck and it launched earlier this year.
It comes with an opulent lounge featuring floor-to-ceiling windows, an owner's cabin bigger than most London flats and space for 20 guests and 54 crew.
Melnichenko is the main shareholder of EuroChem, one of the leading fertiliser producers in the world.
Sailing Yacht A is the latest addition to the oligarch's fleet. He is also the proud owner of smaller vessel - Motor Yacht A - which is itself worth £240million.
