With pedal-to-the-metal gull-wing side openings, and oh-so exclusive decadence, the luxurious Gran Turismo Mediterranea has enough throttle to hit 75 knots - about 85mph. Designed by Rome-based Lazzarini Design Studio, the stunning vessel is equipped with a garage for the owner's supercar. Sleek foil wings deploy to lift the boat - which comes in a Ferrari-style red of course - out of the water at speeds exceeding 20 knots (23mph). Prospective owners also get a sundeck, three to four bedrooms, a kitchen and a cabin for crew as part of the €9million (£7.5million/$10million) price tag.
