With recent activity growth in the field of explorer yachts, marked by introduction of Oceanco's 105-meter explorer concept Esquel and Heesen's 57-metre explorer yacht XVenture, Yacht Harbour looks at the sector's largest yachts. Although the 5 largest explorer yachts launched might change in the near future, today we recall the largest ones built so far.
#5 Andromeda
Yard: Kleven (2016)
This superyacht built in 2015 was originally christened Ulysses, later in 2017 that name was handed over to her bigger sister. Andromeda was owned by New Zealand businessman Graeme Hart, up to her sale in 2017, which became the largest that year asking $175 million.
With her naval architecture developed by Norwegian Marin Teknikk and exterior design by Oscar Mike, Andromeda was produced by companies earlier known for building commercial offshore vessels. She features a helicopter pad with a hangar, as well as storage space for a 21-metre tender that requires a special crane.
#4 Le Grand Bleu
Length: 112.8m
Yard: Bremer Vulkan (2000)
Built by Bremer Vulkan and launched in 2000 with a Bannenberg & Rowell interior design, Le Grand Bleu was commissioned by John McCaw, US telecom magnate, but then sold to Roman Abramovich who enhanced it with a 16ft swimming platform. Le Grand Bleu was then passed to Eugene Shvidler, friend of Abramovich and business partner, in 2006.
Le Grand Bleu is featured with many options ensuring perfect exploration travelling. Her large tender capacity enables her to house two sports boats, a 22-metre Dubois sailing yacht and 21 metre Sunseeker motor yacht, not to mention a Land Rover that can be used to explore territories ashore.
#3 Luna
Length: 115m
Yard: Lloyd Werft (2010)
Refreshened through a €50 million refit that came following a change in ownership, Luna was delivered in 2010. Currently the 3rd largest explorer in the world, her open aft deck and swimming pool have set a standard for the yachting industry.
Built for Russian billionaire, Roman Abramovich, Luna was originally intended as a more sleek version of her owner's existing explorer, the 113-meter Le Grand Bleu. At the time of her launch, the swimming pool installed on Luna was the largest that anyone had ever seen onboard a superyacht.
Luna's current owner, which Forbes names as Farkhad Akhmedov, purchased the yacht from Abramovich in 2014. The man, valued at $1,3 billion by the magazine, later initiated a 14-month refit in Germany that gave the yacht a sleek exterior look and implemented several improvements on one of the world's most iconic yachts.
#2 Ulysses
Length: 116m
Yard: Kleven (2018)
The enhanced, larger version of the 107-meter Ulysses (now Andromeda), this yacht was also built by Kleven in Norway for New Zealand-based billionaire Graeme Hart.
Ulysses' naval architecture was developed by Norwegian design house Marin Teknikk, with her exterior concept devised by New Zealand design studio Oscar Mike Naval Architects, and interior design by British studio RWD. Her key features include a helicopter hangar at the top deck, along with a storage for Bell 429 helicopter. Ulysses is also equipped with a wide range of tenders, with a 21-metre Princess 68 yacht among others.
#1 Octopus
Length: 126m
Yard: Lurssen (2003)
This largest explorer yacht in the world built by German shipyard Lurssen in 2003, has not been surpassed in 16 years. She belonged to Paul Allen, one of Microsoft founders, who passed away in late 2018. As Allen once said: "Octopus is less a Bentley than a Range Rover".
As part of this, the yacht is fitted with two submarines, one of which can dive for up to 8 hours with 10 people on it, the second submarine can be remotely controlled. Thanks to this equipment, Allen and his crew were able to locate a WW2 era battleship at the bottom of the ocean in the Philippines.
The billionaire had previously also made available his yacht to the Royal Navy in order to find a British battleship underwater. On a leisure side, Allen lent Mick Jagger the recording studio onboard for him to record an album in 2011, other performers have included Usher, U2 and Johnny Cash.
The largest explorer yacht in the world, Octopus can accommodate up to 26 guests thanks to her spacious staterooms and is operated by a crew of 60. Other amenities found onboard include a second helipad, a swimming pool and a music studio as well as a courtyard-like set up on the third deck of Octopus occupied by guest space.

Swiss energy company Repower has unveiled Lucietta, Venice's first fully electric water taxi, marking a significant advancement in sustainable marine transportation for the historic city. The 9.3-meter vessel, designed by Nauta Design and built by Murano's Cantiere Serenella shipyard, debuted at the Venice Boat Show and will serve during the 2025 Venice Film Festival before entering regular service.Constructed using a combination of traditional Venetian boatbuilding techniques and modern sustainable materials, Lucietta features a lightweight carbon fiber hull and incorporates recycled Murano glass elements developed by local startup Rehub. The construction process maintained Venice's strict dimensional constraints for canal navigation while implementing contemporary electric propulsion technology.The vessel is powered by a 200kW electric motor with a 180 kWh battery system specifically optimized for Venice's operating conditions. Performance specifications include a top speed of 30 knots (55.5 km/h) and sufficient battery capacity for a full 8-hour workday at typical lagoon speeds of 7-20 km/h. Compared to conventional diesel water taxis, Lucietta completely eliminates direct emissions during operation and reduces energy consumption by approximately 60%.Environmental impact projections indicate each Lucietta water taxi will prevent about 12 tons of CO2 emissions annually while completely eliminating particulate matter emissions. The electric propulsion system also reduces noise pollution from 85 dB to 45 dB - an 85% decrease that significantly improves the acoustic environment of Venice's canals. Over its operational lifetime, the electric taxi is expected to have 30% lower maintenance costs than combustion engine models."Electric boating represents a crucial part of the sustainable mobility revolution," stated Fabio Bocchiola, CEO of Repower Italia, noting the European electric boating market is projected to reach $13 billion by 2030. The project builds on Repower's previous electric boat initiative that received a Compasso d'Oro honorable mention in 2020.Nauta Design's Massimo Gino explained the design process: "We studied original taxi designs and interviewed operators to create a modern electric version that respects Venice's strict dimensional constraints for canals and bridges." The collaboration with local artisans at Cantiere Serenella ensured the preservation of traditional Venetian craftsmanship while implementing sustainable technologies.Lucietta can accommodate up to 14 passengers and will initially serve during high-profile Venice events before expanding to regular water taxi service. The introduction coincides with Venice's increasing restrictions on combustion engine vessels in its sensitive lagoon ecosystem, positioning electric water transportation as a viable solution for the city's unique mobility challenges.Credits: Nauta Design
