Why complete your SSI Open Water Instructor course in Koh Tao?
Our SSI Open Water Instructor course focuses on real training, practice, and confidence-building. You learn directly from experienced instructor trainers, with maximum exposure to divers of all nationalities and levels. Koh Tao is ideal for this:
- Warm, clear water year-round (28–30°C)

In addition, training as an SSI Open Water Instructor at The Divers Boat means being immersed in a working dive centre from day one — both boats, real students, real briefings. If you haven’t yet completed your Divemaster certification, we can plan both programmes back to back.
