Its location is a study in contrasts. The hut that serves as the office neighbors the Crandon Marina boat ramp. Clean sailboats, ranging from 22 to 25 feet, are dwarfed by humongous powerboats that slide from their trailers into the water. As the wind-driven craft languish, high-pitched outboards burn fossil fuel and make waves on their way to Biscayne Bay. But to seasoned sailors, the differences serve as a noisy reminder of the therapeutic qualities of their avocation. And there's a bonus: The location allows sailors to reach the shadow of the Miami skyline in less than fifteen minutes. Rates start at $27 per hour; daylong cruises go for $129 and up. Weekend packages are also offered. Basic sailing knowledge is, of course, required. And that means more than identifying port and starboard. If you don't know more, lessons are available beginning at $35 per hour.
