The catamaran eases out of Boot Key Harbor and the harbor’s calm blinks away behind you as the channel opens to a sweep of shallow, turquoise water. Sunlight rides the bow and the sandbar ahead sits low and luminous—an improvised island where people drift on noodles, stand on paddleboards, or simply let the current whisper them into a slow, easy day.
