Porsche Design Studios has created its first ever boat, set to debut at next week's Miami Boat Show. The 28-foot-long high-speed cruiser is a collaboration with Fearless Yachts, and looks like the boat Batman would have if he were real. It has a fiberglass hull, a 525-horsepower Viper engine, and can reach a top speed of 80mph. And at $300,000 you'll only have to sell your home to own it. And maybe your car. It's almost too cheap.
