This insane concept super-yacht created by French interior designer Yelken Octuri, is called “flying boat.” Clever, right? This trimaran sailing yacht has four additional engines, and is 46 meters in length. It also has four masts that turn into wings by clicking on a button. Flying boat consists of two main decks, including the ground floor with a gallery and the main saloon and an upper deck with three cabins. Not bad.
