A low-profile catamaran slips away from Reefhouse Marina and the ocean opens like an invitation — warm, blue, and streaked with sun. Within minutes the shoreline of Key Largo blurs into horizon; feathered gulls wheel as the captain calls the first dive site. Below, coral formations rise and fall like submerged architecture, and the current teases your fins, daring you to read the reef's rhythms.
