A superyacht that belonged to late Microsoft cofounder Paul Allen has hit the market for 295 million euros, or about $325 million, yacht brokerage Burgess told Business Insider.

The 414-foot yacht, Octopus, has eight decks, an elevator, a cinema, two helipads, and a glass-bottomed underwater observation lounge. Allen reportedly paid about $200 million to have the superyacht built by Lürssen. It was officially launched in 2003.

Allen was known for hosting star-studded parties on his yacht during the Cannes International Film Festival in France. Guests have reportedly included George Lucas, Mick Jagger, Karlie Kloss, and Chloe Sevigny.

The vessel is one of several assets the late billionaire's estate has put up for sale since his death, including a $110 million Beverly Hills property and a MiG-29 fighter jet.
