Why Choose Our Dive School?
Internationally Recognised SSI Training
The Divers Boat is a certified SSI (Scuba Schools International) training centre. SSI is one of the largest diving organisations in the world. As a result, your certifications are valid everywhere on the planet. You can dive freely after your training, wherever you are.
A Passionate, French-Speaking Team
Our instructors speak French, English, and Spanish. This is a real advantage for non-English speakers. You learn in a language you are comfortable with. Moreover, our team is known for its patience and professionalism. They quickly build confidence, even in the most hesitant students.
Small Groups for Personal Attention
We keep our group sizes small. This way, every student receives individual guidance. You progress at your own pace. This is one of the key differences from larger dive shops on the island.
A Dedicated Training Boat
Our boat the “White” is reserved exclusively for courses. It departs every morning to the best sites around Koh Tao. All equipment is already on board. You do not need to carry or rent anything separately.
