Exhibitionist by name, exhibitionist by nature, Swedish design studio Gray Design have created the ultimate in luxury sea transport, the appropriately titled Exhibitionist yacht - also known as the supercar of the sea. The sea vessel is packed with sports car features like its dark grey hull, low stern and solar-paneled platform. It even comes with its own matching automobile, the Xhibit G, to complete the extravagant package. The interior takes decadence to a whole new level, with Art Nouveau-inspired styling and a dual staircase, along with a space large enough to be used as car showroom. With the hybrid drive engines housed behind glass walls, this Batman yacht combines the latest technology with outrageous opulence.
