|Octopus, the largest private yacht in the world|
Octopus is currently the world's eighth largest superyacht, owned by Paul Allen, the co-founder of Microsoft.
Octopus measures 414 feet, sports two helicopters on the top deck and a 63-foot tender docked in the transom (one of seven aboard). The yacht also has a pool on board, located aft on one of her upper decks, and two submarines: one operated by remote control for studying the bottom of the ocean. Side hatches at the water line form a dock for jet skis.
