On styling alone, the $15 million Adastra is pretty ridiculous. Commissioned by Hong Kong shipping magnate Anto Marden, this luxury yacht was almost entirely custom-built, from its carbon fiber and Nomex honeycomb exterior to its hull made of a glass and kevlar foam. It’s quite to safe to say, if you can get a lady on this thing, you will be using the sumptuous master bedroom. Better have that Arbor Mist on ice.
