Sigrid (Siggi) Lottra, SSI Instructor Trainer und DAN Instructor Trainer

In former times she was a competitive swimmer and seems to be born in the water anyway. Diving is her passion.


Siggi is responsible for the Shop at Tropical Divers. The choice for Bonaire was easy for her after a first contact on vacation, since she felt in love immediately with this marvelous island. Beside the administration she takes care - just like the remaining team of the Tropical Divers - about training and consulting of our divers. From the first contact at Try Scuba Diving up to the professional education, including all specialty classes from SSI and DAN, Siggi will be happy to assist you. If you want to become a dive professional, Siggi will conduct the Instructor Training programs (ITC) at Tropical Divers.

Claus Harald (Harry) Neumann, SSI Instructor Certifier und DAN Instructor Trainer

... is our Bonairean Dinosaur and the only one, who profess himselve publicly to his second first name. He is also working as a SSI Certifier in the Caribbean.

As a specialist for underwater photography it is unusually to find him without strobe and camera underwater. Only for the education of divers he puts these gladly to the side. If you like it silent, ask Harry for a Discover Rebreather or SideMount Diving. He will be happy to explain you all the pro’s and con’ of this special kind of diving ... and will take you out for a dive.

If he is not diving he cares for administration and marketing or tortures our computers and servers. On special request he will prepare his Caipirinhas at our Pool bar. Some people say, his Caipirinhas are world-famous.

If you like to know something about the dive spots on Bonaire or about underwater photography ... please ask 

Peter König, SSI Open Water Instructor

Peter is the Petty Officer Engineering Technician and also the youngest member of our team. He is also responsible for the maintenance of our compressors and all electrical or electronic related problems within the resort.

After being on vacation on Bonaire he felt in love with our beautiful island and decided to move his focus to Bonaire. Honestly, we can fully understand him :-)
