Octopus is the most recently built yacht of Paul Allen, one of the founders of Microsoft, who also owns the 92.38 metre Tatoosh.
Octopus features a helicopter pad and garage aft and can also accept a second helicopter on the bows. A 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 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.
Octopus is currently the largest explorer yacht in the world.
