If a large yacht somehow fails to adequately convey fabulous wealth to you, then maybe a large flying yacht will do the trick.
Airplane designer Yelken Octuri has come up with a plan for just such a thing: a 150-foot yacht that transforms into a seaplane.
As you can see in this video from GeoBeats News, the 150-foot yacht has four mobile masts that can transform into wings, making the transition from boat to plane fairly seamless, at least in theory. Once in seaplane mode, the yacht has a range of 600 kilometers (about 370 miles).
But don't expect to be able to blow your millions on this boat-plane just yet: Octuri's design, commissioned by three Omani princes, has been on the drawing board for at least a few years.
Correction: An earlier version of this story mistakenly translated 600 kilometers into about 370 feet instead of 370 miles.
