The boat eases away from Chatan’s fishing port and the Okinawan coastline shrinks into a gleam, the sea opening like a map you can walk on with your eyes. In an hour the Kerama islands loom—clear-water bowls where coral gardens hold fast and green turtles glide through sunlit columns. The current nudges you toward shallow bommies and sandy channels; instructors anchor the experience, and flotation jackets keep the boat-side scenes relaxed and steady.
