In short

When Lürssen delivered Octopus in 2003 she was by a wide margin the largest explorer yacht yet built, and Boat International notes that she is widely considered the first true explorer (Boat International, Boat International). Espen Øino drew her to a brief that pointed to the Finnish icebreaker Fennica: every tender, the submarine and the helicopters had to be carried out of sight, so the stern hides a 36-metre floodable dock and her decks carry two helipads and a hangar for two helicopters (Boat International). With an ice-class 1A steel hull and a range of 12,500 nautical miles at 12 knots she has worked along the Antarctic coast and through the Northwest Passage (Boat International), and in March 2015 her expedition team found the wreck of the Second World War battleship Musashi in the Sibuyan Sea (YachtBuyer). Sold in August 2021, she has since taken charter guests to Antarctica, reaching James Ross Island and Anvers Island, and in 2024 she completed a nine-month refit at Lloyd Werft in Bremerhaven (Boat International, Boat International).

About 12,500 nautical miles at 12 knots, according to Boat International; YachtBuyer gives the same distance at 12.5 knots and 7,100 nautical miles at her top speed of 19 knots. Her tanks hold 1,034,000 litres of fuel. How many days she can stay at sea without resupply has not been published.
What ice class is Octopus?
She has an ice-class 1A steel hull (Boat International). Under the Finnish-Swedish ice class rules, 1A is meant for difficult ice conditions with icebreaker help when needed, and the hull is designed for level ice up to 0.8 metres thick (Finnish Transport and Communications Agency). It is not a Polar Class, and the full class notation of Octopus has not been published.
Does Octopus have a helicopter pad and a submarine?
Yes. She has two helipads, aft and on the foredeck, and a hangar for two helicopters. Her original submarine was Pagoo, a custom 10-person craft; in 2022 a Triton 3300/6 was due to replace it in early 2023 (Boat International). She also carries an ROV rated to 2,700 metres and a dive centre with a hyperbaric chamber (Boat International).
Where has Octopus been?
Boat International reports voyages along the Antarctic coast and through the Northwest Passage (Boat International). In 2015 she found the wreck of the battleship Musashi in the Sibuyan Sea, Philippines, and helped recover the bell of HMS Hood (YachtBuyer). After her 2021 sale she cruised Mexico and Brazil, passed the Panama Canal and spent the 2022–23 season in Antarctica (Boat International); her 2024 itinerary included Svalbard and Greenland (YachtCharterFleet).
Who built Octopus, and who was she built for?
Lürssen built her, with a partner yard in Kiel, to an exterior design by Espen Øino, with original interiors by Jonathan Quinn Barnett (Boat International). Her keel was laid on 27 April 2001 and she was delivered on 11 December 2003 (YachtBuyer). Boat International reports that she was delivered for Microsoft co-founder Paul Allen, who died in 2018; she was sold in August 2021, and the new owner has not been named (Boat International).
Can you charter Octopus, and is she for sale?
She is listed for charter by brokers including Northrop & Johnson (October 2026). She is not listed for sale (YachtBuyer); her last public asking price, before the 2021 sale, was €235,000,000 (Boat International).
