You step off the jetty into a warm breeze and the boat threads a corridor of islands — the sea pressing bright and blue around you. In twenty minutes the boat slows at a shallow reef; instructors check helmets, straps and smiles. The seawalking helmet keeps your hair dry while the world below leans in: butterflyfish thread through coral bommies and sunlight fingers down to a sandy seabed.
