• Andrey Melnichenko's £360 million ($480 million) "Sailing Yacht A" has been spotted again, this time in the Port of Gibraltar.
• The 142.8-metre vessel boasts 300 ft masts, eight decks, a huge swimming pool, and an underwater observation pod.

Russian billionaire Andrey Melnichenko's £360 million ($480 million) "Sailing Yacht A," one of the largest private sailing yachts in the world, has been spotted docked at the Port of Gibraltar. The yacht underwent final tests at the port in May before it was handed over to its owner.

The 142.8-metre vessel boasts 300 ft masts that are taller than Big Ben, and counts eight decks (connected by a series of lifts), a free-floating spiral staircase, a huge swimming pool on the top deck, and an underwater observation pod among its stunning features. France's Philippe Starck is behind the design.

Onlookers and yacht enthusiasts shared some close up shots of the vessel while it was docked at the port.

The style of the yacht has divided opinion, but it is nevertheless one of the most closely followed superyachts in the world.

As the sun set the vessel apparently prepared to set sail again.

Owner Andrey Melnichenko is worth an estimated $13.7 billion (£10.2 billion), according to Forbes.

Business Insider last reported a sighting of Sailing Yacht A in Ibiza in September, when UFC star Conor McGregor stumbled upon it while holidaying with his family. McGregor proceeded to freak out at the sheer size of the vessel and took some up close shots of it while on his jet ski.
