You step off a low-profile charter into water so clear the hull seems to float above the reef. Salt air pulls at your hood; below, coral gardens fan and a green sea turtle glides like a slow-moving thought. A certified in-water guide points, and you move from one pocket of life to the next — Christmas tree worms tucked into brain coral, French angelfish patrolling ledges, and purple sea fans swaying with the current that dares you to follow.
