Don't let its aggressive outward appearance fool you — belowdecks, the Wally 55 Powerboat ($2.4 million) is every bit a luxury sports cruiser. Available with two or three cabins, and space to accommodate a crew member, it can comfortably sleep up to five passengers. A fully-appointed galley and several restrooms with showers mean you don't have to leave the comforts of home when you take to the sea. Four Volvo IPS600 engines producing 435 horsepower apiece push this yacht through the water at an impressive pace of 40 knots. The deck has plenty of space for sunbathing and relaxing (concealed by a wraparound windscreen), and a hydraulic swim ladder makes a perfect launch point for taking a dip.
