Going Great White Shark Diving in South Africa and more specifically a trip on the Slashfin, is a combination of goosebump thrills, education and relaxation on a luxury boat in the company of experienced experts and researchers! They will show you how to distinguish between a male and female shark and how to identify a specific shark by its unique dorsal fin and scars. The 20 – 25 minute boat trip to where the activity is to take place, is by itself an exhilarating adventure.

Named after a legendary 3,3 m male shark with a very distinctive dorsal fin, the Slashfin is a unique, multi-million rand aluminium boat custom designed for speed, stability, safety and space and can comfortably accommodate 40 passengers and the crew at a time.

On any given day, we also usually see at least two or more members of the Marine Big Five – sharks, dolphins, whales, seals and penguins, as well as several bird species.


In the morning, before your trip to sea and while you are having your breakfast, we offer an in-depth audio-visual briefing introducing you to the local eco-system and to your excursion in our comfortable conference room equipped with a DVD player and two big screen TV’s. This will help you to become familiar with the boat, the crew, the concept of chumming and what you can expect to see during your excursion. It will also give you some guidance as to the safety issues related to boats and Shark cages. In the afternoon following your excursion, we have an optional presentation presented by one of our three Marine biologists. This presentation will give you an insight into general Shark biology and conservation, and present some of the research work conducted on White Sharks in South Africa.
