Octopus
The Octopus, a 414-foot yacht, once owned by the estate of Microsoft cofounder Paul Allen has 41 suites and cost over $150 million to build. The Octopus is equipped with a pool, two helicopters, a movie theatre, a basketball court and a recording studio. This yacht was also pictured in May during the Cannes Film Festival. The yacht is now reportedly for sale for just under £270 million.
