When this Fort Lauderdale favorite recently opened up shop down our way, the owners chose its location wisely: the Miami Beach Marina. From here you have a wide variety of navigational options, unlike many other rental operations. You can spin through the vastness of Biscayne Bay, cruise the waterways and cozy canals behind gorgeous luxury homes, or head out to the open Atlantic, where the chop will test your riding skills. East Coast Water Sports features brand-new 2002 machines and charges $65 for a half-hour. If you want more time, they can arrange a discounted rate -- but be sure to ask first.
