Miami has so many waterways that it would seem appropriate if residents got boats when they reach the legal driving age. But time, money, and an overall dislike of having to anchor your vessel might deter you from actually purchasing one. Luckily, Club Nautico has an entire fleet of powerboats and luxury yachts to rent for four or eight hours. You can take the yellow-paneled Buddy's Joy, a 23-footer, for a sunset ride to Stiltsville, or jet to Brickell on the 34-foot Primetime for an expensive lunch. Some models have convenient swim platforms, others feature full galleys and wet bars, but none comes with Dramamine, so bring your own. With prices starting at $899 for a half-day (and specials on Tuesday and Wednesday), you and your homies can definitely afford to spend some time on the high seas. Just don't let that kid Gilligan take the wheel.
