You step off the dock with salt on your lips and the Caribbean spread like a bright, restless floor beneath the boat. Instructors gesture toward the pale shapes of submerged sculptures nearby; the sea here doesn't just receive visitors, it challenges them — currents nudging, thermoclines reminding you that this is an environment with its own rules.
