Designed by Philippe Starck and built in 2008, the unconventional 119m long luxury yacht has a distinctive knife-like hull. The $300million yacht was built for Russian billionaire Andrey Melnichenko but it was reported earlier this year he was selling the vessel after having a new, even bigger, $450 million yacht built.
