Yachts are for poor people. This is Kokomo Ailand, a mobile private island developed by Migaloo Private Submarines (who specialize in submersible yachts). They haven't actually built one yet, but claim they can immediately with existing technology provided someone forks over the cash. The penthouse sits 260-feet above sea level and options (including a jungle deck with waterfalls, glass-bottomed Jacuzzis and pools, helipad, submarine docks, etc etc) are basically unlimited because you're a billionaire. Alternatively, buy a stationary island like a non-@$$hole. You inherited a bunch of family money, you're not a Bond villain.

Hit the jump for a bunch more shots and a video of even more renderings.

Thanks to Steven HB, who would be happy to own a kayak.
