SeaUrchin Flic en Flac, west coast diving

German management.

Individual, highly professional and with total commitment to the environment.

The SeaUrchin Diving Center was founded in 2006 by Katharina Dohmann and is among the most experienced Diving Schools in Mauritius. “Under German management”, our professional Diving Team prides themselves on their level of empathy toward the needs of our customers.

We dedicated ourselves to raising awareness about the importance of the underwater world and its fragility has always been one of our main concerns. Diving is not only a sport but it’s also an essential tool for the study of this world from which we can learn a lot. We believe that we have to realize the impact of mankind on this fragile environment and have to work together for its preservation.

The Dive Center is affiliated with SSI – Scuba Schools International and CMAS (IDA for Germany and MSDA for Mauritius), thus we are the only Diving School in Mauritius that offers three different diving formations with SSI, PADI, and CMAS courses. Our multi-national team allows us to teach courses in English, French, German, and Danish. Thus we guarantee a theoretical and practical training accessible to everyone.

Further to this the SeaUrchin Diving Center is the only SSI Diamond Instructor Trainer Center in Mauritius. Katharina is as SSI Instructor Trainer authorized to form and train any diver to a professional level. We have SSI & CMAS Instructor Courses at least twice per year.

We always endeavor to offer courses in small groups, never exceeding six people to a group. Any dive you enjoy with us will, of course, be guided by one of our team, not only for your safety and well-being but also to ensure that you get the most from your time spent with us.

Of course, we want you to feel at home after your diving session, so you are welcomed back to the Center to indulge in a selection of complimentary hot drinks and the chance to have a shower.

Khaleah is the youngest of the two daughters of Katharina, making her the second generation at SeaUrchin. She basically grew up in the DiveCenter and at the Ocean. Said so, she’s a natural mermaid and learned to dive in a very very young age. There is nothing she can’t spot underwater even if she sometimes loses the DiveSite, it’s always inspiring to dive with her. Khaleah became an SSI DiveGuide and DiveMaster at age 15.
