An iconic explorer superyacht OCTOPUS that still holds the title of the largest explorer yacht in the world with her 126.2-metre LOA has been listed for sale. The news comes 11 months after the yacht’s passionate owner Paul Allen, Microsoft co-founder, investor and philanthropist, sadly passed away at the age of 65.

A renowned world-class cruiser and one of the most well-travelled yachts in the global fleet, OCTOPUS encompasses eight decks and an interior volume of 9,932GT with exteriors by renowned Espen Oeino, along with interiors by Jonathan Quinn Barnett of Seattle.

With accommodation for up to 26 guests across 13 cabins, and 63 crew across 30 cabins, OCTOPUS has explored multiple destinations since her delivery in 2003, including the coast of Antarctica, traversed the Northwest Passage and recovered the ship’s bell from the wreck of HMS Hood at a depth of 2.8km for the Royal Navy. 

OCTOPUS has two helicopter[ pads on the main deck, a twin pad and hangars at the stern and a single pad on the bow; and a 19 m tender docked in the transom and a landing craft. There are a total of seven tenders aboard. The yacht also has a pool, located aft on one of its upper decks, and two submarines (one of them operated by remote control and capable of attaining greater depths). The latter was lent to Google Earth for the “Explore the Ocean” project. Side hatches at the water line form a dock for personal watercraft.

The exterior was designed by Espen Øino Naval Architects and built by the German shipbuilders Lürssen in Bremen and HDW in Kiel. The interior was by designer Jonathan Quinn Barnett of Seattle.
