Luxury yachts nowadays often cost over 100 million dollars. Massaud.com proposes the Manned Cloud a flying hotel /cruise ship. It looks like a futuristic whale and is "planned" for 2020.On the other hand two ex-computer programmers near Boston are working on selling the black and yellow Sky Yacht (see the video) personal blimp. They plan on selling them for less than 250 thousand dollars. I think most woman would rather show up in St. Tropez in something that looked more like the Manned Cloud. It even has a sundeck on top.
