Marine Dynamics Shark Tours answers the most frequently asked questions:

Q: Do I need a diving certificate?

A: No. The cage is attached to the side of the boat above the surface and extends two meters underwater. As a shark approaches, you will be instructed where to look and when to go down to see the shark below the surface.

Q: Can I go outside the cage?

A: No, and that goes for your arms and legs too.

Q: Do I need to get into the cage to see sharks?

A: No. The high viewing deck on Slashfin makes surface viewing a pleasure.

Q: Do I need to bring a wetsuit, a mask, weights and a towel?

A: No. All you need to bring is your bathing suit, sunscreen, a camera, and something warm to wear. Even on a hot day, it can get chilly out at sea. Everything else is supplied.

Q: Are there any age restrictions?

A: No. The oldest cage diver was 100 years young, and the youngest shark enthusiasts have still been in nappies.

Q: What time will the sharks arrive?

A: Sharks are just like any other wild creature. They come and go as they please so there is no roster.

Q: Do you feed the sharks?

A: No. We use a scent trail of fish products called “chum” to attract the sharks in the area to our vessel. Once nearby, we keep the sharks' short attention span by using a bait and seal decoy. While sharks can get the bait, this is not done to provide them with food.  

Q: When is peak viewing season for white sharks?

A: We consider our winter months, April - September, the best time of year to cage dive with white sharks because they frequent the seal colony at that time of year. However, winter is also the worst time of year weather-wise, so plan a few possible days during your holiday for your cage dive.

Q: How long does a trip last?

A: Typically, trips last three to four hours. However, the duration of a trip depends on shark activity, weather conditions, and tides. Set aside a day for this adventure.

Q: Do you offer a shuttle service to and from Cape Town?

A: Yes! The shark shuttle runs return trips to Cape Town city centre daily.

Q: Should I take anti-motion sickness medication?

A: If you are worried about it, yes, rather be safe than sorry. Anti-motion sickness medication is inexpensive and readily available over the counter at any South African pharmacy. 

Q: Does cage diving benefit sharks?

A: Like all wildlife activities, it depends on the operator. Every client that dives with Marine Dynamics directly supports white shark conservation by automatically contributing to the locally registered non-profit organisation, Dyer Island Conservation Trust.



“I loved it! It was an experience I will carry with me and remember forever! Despite the odds, Marine Dynamics were able to take us out for a fantastic day with three shark sightings. And if that isn't enough, we also saw a few southern right whales. I would recommend them again and again!”  Indigo French
“We went shark cage diving with Marine Dynamics and it was a spectacular experience. The staff and the marine biologist on board were bubbly and friendly. Everything you need is provided. All you have to bring is your bathing suit. The rates include a light meal before the trip and hot soup when you return. While on board, they provide snacks and sweets to help with motion sickness. There is hot chocolate when you get out of the water. Wet suits, masks, towels and blankets are supplied. I felt well taken care of. The whole experience is filmed using a GoPro and is offered to you to purchase at the end. We had a memorable time. We saw several bronze whaler sharks and three broadnose sevengill sharks.”  Kimone Pillay
“We had a fantastic time shark cage diving with Marine Dynamics. We chose them after researching the ethics of the activity. MD stood out among the rest for the methods used during the dives and also for their extensive conservation work. They are part of the Dyer Island Conservation Trust. As their website indicates, great white sharks are a rare sighting, and we did not see any. However, we saw plenty of bronze whaler sharks, a Cape fur seal, and hundreds of Cape cormorants. The guide on the boat was very informative. They provided an orange waterproof jacket, a wetsuit, booties, goggles, a shoulder weight, and a life jacket. A videographer was on board and the video is sent to you if you buy it. You can also bring your own GoPro. They had a driver collect us and others from our hotels in Cape Town to drive us there and back (two hours each way). To get this you must choose the package with the return trip option (for Americans reading this, "round trip" in South Africa means "return"). The drive to Kleinbaai was beautiful and provided an excellent chance to see the countryside. Our driver was friendly and answered all our questions along the way. We learned interesting things about the country by talking with him. It was a great experience. Highly recommended!”  K Reu
