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.

Wear a UV swim top
Sun reflects strongly off the water; a long-sleeve UV shirt protects skin and reduces need for sunscreen on the back.
Bring a lightweight dry bag
Keep phones, medications, and a dry change of clothes safe from spray and splashes in a small dry bag.
Hydrate and eat lightly
Have a light meal and water before boarding—sea conditions can suppress appetite and dehydration increases seasickness risk.
Know the weight & age limits
The operator enforces strict age and weight limits for safety—confirm eligibility before booking to avoid issues at check-in.
Rash guard or UV swim shirt
Protects skin from sun and reduces abrasion from life jackets and fins.
