Azzam longest superyacht in world

Dilbar biggest by internal volume

Four new entries in prestigious Top 101 list

CNN  — 

It’s the world’s biggest superyacht by volume, with the biggest indoor swimming pool, but the deluxe Dilbar ranks only fourth in a prestigious Top 101 list of luxury leviathans.

Delivered to Russian oligarch Alisher Usmanov this year, Dilbar is the highest new entry on the list with a length of 156 meters (511 feet), including a 25-meter indoor pool.

But it trails in the size stakes behind the 180-meter (590-foot) mega-yacht Azzam, which launched in 2013, reportedly for United Arab Emirates President Khalifa bin Zayed Al Nahyan, at a cost of about $600 million.

Roman Abramovich’s Eclipse (162.5 meters/533 feet) is the second biggest ahead of Sheikh Maktoum’s Dubai (162 meters/531 feet) in Boat International’s annual list of the biggest superyachts on the planet, ranked by length.

Dilbar’s gross tonnage – the measure of internal volume – dwarfs the others at 15,917 GT with 3,800 square meters of space for Usmanov, a majority shareholder in Arsenal Football Club, and up to 40 guests.

Built by German manufacturer Lurssen, the boat can maintain a constant speed of 22.5 knots from a 30,000 kW diesel electric power plant. It houses two helipads and can accommodate a seven-ton Airbus H175 helicopter.

Dilbar is the largest of four new entries in the list, alongside Las Vegas developer Steve Wynn’s 92-meter Aquarius (at No. 50), 90-meter Lionheart (No. 59) – built for controversial British retail magnate Philip Green – and 83-meter Here Comes the Sun (No. 82).

“Dilbar is a mammoth project,” Boat International editor Stewart Campbell said. “She’s often in Antibes and dwarfs everything in the harbor.

“She joins some incredible new yachts in the Top 101 this year, but it’s 2017 that has us most excited, with up to 12 new superyachts joining the ranks of the world’s biggest boats.”

Dilbar replaces a yacht formerly of the same name – now called Ona (110 meters/377 feet) – as Usmanov’s largest vessel.

Russia features 19 owners on the Top 101 list, followed by the US with 17 and Saudi Arabia with nine, says Boat International.

A record number of 52 yachts exceeding 250 feet in length are in the pipeline to be built, according to industry figures.
