ONE of the world's biggest super-yachts has arrived in Weymouth Bay.

It arrived in Southampton on June 5 after a week-long voyage from Barcelona and has now dropped anchor off Weymouth.

The 156-metre Dilbar, said to be worth an eye-watering $650m, proved to be a spectacular sight as she made her entrance into the bay.

Luxury facilities on board the huge vessel include almost 60 cabins and two helipads on the bow and aft of the upper deck.

Dilbar is the fourth largest yacht in the world by length but the biggest in terms of gross tonnage (15,917) and interior volume.

Her 30,000kw diesel electric power plant, thought to be a record for a super-yacht, gives her an impressive cruising speed of 22.5 knots.

She is owned by Russian billionaire Alisher Usmanov, who is not thought to be on board.

Two years ago Usmanov was estimated to be Russia's fifth richest man, with a net worth of $16 billion. He is best known in business circles as the main shareholder of USM Holdings.

Dilbar took more than four years to build.

The luxury mega-yacht was launched on November 14 2015 at the Lurssen shipyard in Bremen, Germany, and delivered the following year.

Equipped with an Airbus H175 helicopter, she is 512ft long with a beam of 79ft and a draft of 20ft.

She has a displacement of 1,230 tons - the equivalent of around 186 elephants.

Described as one of the most complex and challenging yachts ever built, her recreation facilities include a 25-metre pool which holds 180 cubic metres of water. She can accommodate 36 guests and 84 crew.

Three years ago Dilbar was named the winner of the 2017 World SuperYacht Award for Motor Yacht of the Year.

VesselsValue says the magnificent craft is worth $650m.

The purpose of her visit to Weymouth - and the likely length of her stay - is not known.
