Octopus is a 414 foot (126 m) megayacht owned by Paul Allen, the co-founder of Microsoft. Octopus sports two helicopters on the top deck, and a 63-foot tender docked in the transom. There are a total of seven tenders aboard. The yacht also has a pool, located aft on one of her upper decks, and two submarines (one of them operated by remote control for studying the bottom of the ocean). Side hatches at the water line form a dock for jet skis.
