At the top of the private boating world, length is measured against ships rather than boats. Builders such as Lürssen, Blohm + Voss and Nobiskrug have turned out vessels with their own helipads, pools and crews, and ownership of several has made headlines. Here are eleven giants, ranked roughly by size, that show how far the superyacht has stretched.

1. Azzam: The Longest Afloat

At 590 feet (180.6 m), Azzam is the longest yacht afloat, and more than 4,000 people built her at Lürssen for a 2013 delivery, according to Luxe Digital’s ranking. She leads the list by a clear margin.
The scale of the workforce is a reminder that a yacht of this size is an industrial project comparable to a small ship. Her length sets the ceiling against which every other vessel here is measured.
2. Eclipse: Abramovich’s Blohm + Voss Giant

Roman Abramovich’s 162.5-metre Eclipse was built by Blohm + Voss and delivered on 9 December 2010, as her Wikipedia entry records. Her length places her near the top of any ranking of private yachts.
Eclipse is a useful example of the German yard tradition at scale, and her exact delivery date makes her an easy reference point. She is the largest vessel on this list that is publicly tied to a named owner.
3. Dubai: Third In The Register

Dubai is ranked third-largest in the world at 162 metres in Boat International’s register, according to the Boat International register. That places her just behind the two longest vessels in the field.
A third-place rank is a reminder that the top of the list is crowded with ships of nearly the same length. Small differences in metres separate the positions, so the register matters more than any single claim, and readers should expect rankings to shift as new vessels are delivered.
4. Blue: Lürssen’s Recent Giant

Blue is a 160-metre Lürssen launched in 2022, as the list of motor yachts by length shows. She is one of the newest vessels in this group.
Her launch date shows that yards are still delivering vessels near the top of the size scale rather than merely maintaining old records. The German builder appears repeatedly in this gallery for that reason, and she shows that the biggest yards still have order books at this scale.
5. Dilbar: Indoor Pool And Port Ban

The 156-metre Dilbar, linked to Alisher Usmanov, has the largest indoor pool on any yacht and was barred from leaving Germany without permission in March 2022, per the Dilbar article. Her features and her legal status both set her apart.
The pool is a design record, while the restriction shows how a yacht can become a matter of public policy. Both facts explain why the name appears in news well beyond boating circles.
6. Al Said: Oman’s Royal Yacht

Al Said is Oman’s 155-metre royal yacht, built by Lürssen in 2008, as the Boat International register lists. She is the royal yacht in this group.
Royal and state yachts follow a different logic from private purchases, serving as ceremonial and diplomatic platforms. Built at a yard best known for private commissions, she shows that the same builders serve governments and individuals alike. Her presence broadens the list beyond private owners to include a national symbol afloat, a different kind of status from a personal toy.
7. Sailing Yacht A: Biggest Sailing Yacht

At 142.8 metres, Sailing Yacht A is the largest sailing yacht in the register, a 2017 Nobiskrug build according to the Boat International register. She is the only sailing vessel in this set.
Her presence shows that the size race is not limited to motor yachts, even if a sailing design draws a very different silhouette. She stands as the outlier that proves the list is about scale, not just engines.
8. Dragonfly: A Tech Founder’s Lürssen

Sergey Brin’s 142-metre Dragonfly is a Lürssen delivered in 2024, as the list of motor yachts by length notes. She counts among the most recent deliveries at this scale, and the year of delivery keeps the list current.
The recent date makes her a current example rather than a historical one. Her builder and owner reflect how new technology wealth has joined older fortunes in commissioning the largest private vessels, a shift that has reshaped the market for the biggest yards.
9. Opera: A Recent Lürssen Delivery

Opera is a 146.4-metre yacht built by Lürssen and delivered in 2023, according to the list of motor yachts by length. That length places her among the largest private vessels completed in recent years, alongside the other German-built giants in this ranking.
Her delivery date makes her one of the newest entries at the top of the table. Opera also underlines how much of the world’s biggest yacht construction has been concentrated at a single shipyard on the Weser.
10. Rising Sun: Basketball Court, Helipad

David Geffen’s 138-metre Rising Sun is a Lürssen sold to him by original owner Larry Ellison in 2010, and its basketball court doubles as a helipad, the Luxe Digital’s ranking reports. The dual-use deck is the memorable feature.
Such a design shows how space aboard a yacht is engineered to serve several purposes at once. The sale between two famous owners also reflects how top yachts change hands within a small circle.
11. Flying Fox: The Priciest Charter

Flying Fox is a 136-metre Lürssen that charters for around $3 million a week, making her the most expensive charter yacht, as Luxe Digital’s ranking reports. She is the one vessel here best known for hire rather than ownership.
The figure shows that these ships can be rented by those who cannot buy one. It also gives the list a commercial end point, closing with a yacht that anyone with enough money can experience.
