The top 25 largest yachts in the world

Every year, shipyards from around the world push the boundaries of superyacht design to deliver bigger and better yachts. The Samuda-built El Mahrousa may have carried the title unchallenged for a remarkable 119 years, but in the 21st century she has descended down the pecking order to make room for even larger and longer yachts. German shipyard Lürssen currently holds a near monopoly in the construction of supersized superyachts, having delivered 13 of the world’s top 25. But the list is ever changing, with 140 metre Solaris appearing as the newest entry in 2021. These yachts, all measuring over 100 metres, are impressive not only for their hull length but for what they carry above and below deck. From submarines and helicopters to swimming pools, cinemas and science labs, the onboard features of these superyachts show them to be truly ground-breaking pieces of engineering. Read on to discover our official list of the largest, privately owned yachts in the world.

Al Mirqab was built by Peterswerft - Kusch for Hamad bin Jassim bin Jaber Al Thani, the former prime minister of Qatar. Her exterior design is by Tim Heywood and her interiors were styled by Winch Design. She is propelled by five generators that power two electric motors driving conventional shafts and a centrally positioned azimuthing electric pod drive. A grand staircase floats through four floors and surrounds suspended glass artwork by Dale Chihuly. Al Mirqab won Motor Yacht of the Year at the World Superyacht Awards 2009 and Best Interior Design among motor yachts. She can accommodate 60 guests and is manned by an equal number of crew.

Octopus | 126.2m

Built in 2003 ,Germany

Octopus was owned by the late Paul Allen, one of the founders of Microsoft, who also owned Tatoosh. She is one of the largest explorer yachts in the world and was designed by Espen Oeino with interiors by Jonathan Quinn Barnett and Sam Sorgiovanni. Octopus features a helicopter pad and garage aft and can also accept a second helicopter on the bows. Her impressive deck also features a glass-bottom swimming pool which can transform into a dancefloor with a nearby bar for drinks served poolside. Another novel facility of her design is her internal dock, which, opening from her transom, runs forward through the yacht, allowing a 20-metre submarine and a tender of a similar size to float into their storage positions. Once secured, the water is pumped out, leaving them resting on chocks. 

The yacht has a permanent berth in the International Yacht Club Marina in Antibes, where her owner acquired the largest dock by buying the 55.78 metre superyacht Hanse together with its berth – he kept the berth and immediately sold Hanse, which has now been renamed Insignia.

Katara, codenamed Project Crystal, was built by Lürssen in Bremen. It is speculated that her interior is by the late Alberto Pinto. She has one helipad and carries both her tenders and her SOLAS rescue boats in davits port and starboard. She flies a Qatari flag and her home port is Doha, which means her name is probably a variant of the original spelling of the Qatari peninsula Catara, or a translation of the word for celebration. Her owner is speculated to be the young emir Sheikh Tamim bin Hamad bin Khalifa Al Thani making her an official state yacht. She spent her first full season after being launched cruising in the water waters of the Caribbean.

Golden Odyssey | 123.2m

Built in 2015 ,Germany

Known under the project name of Tatiana, this yacht was launched in mid-March 2015 and was moved from her shed at Lürssen’s facility in Lemwerder, Germany for finishing. She was built for Prince Khaled bin Sultan of Saudi Arabia and is a replacement for his well-travelled smaller yacht of the same name. It is said that she was designed by Martin Francis but the designer has stayed quiet on the subject. Her interior is rumoured to be by the late Alberto Pinto. Her steel hull and aluminium superstructure give Golden Odyssey a displacement of 7,600 tonnes and her mostly covered decks suggest a desire for privacy. She is the flagship of the so-called Golden Fleet, which is based at Porto Montenegro in the Bay of Kotor.
