• Shark cage diving in Gansbaai, South Africa with Marine Dynamics. Experience the exceptional and come face to face with a great white shark! 

  • The exact world record white shark is a contested issue, but chances are it is between 6-7m. In Gansbaai, the largest white shark ever caught was at Danger Point and measured up to 5.9m.

  • If you see a white shark in the water don’t panic. Chances are high that the shark has already detected you and isn’t interested. White shark attacks are normally associated with poor visibility, so avoid murky conditions.

  • White sharks have a unique system called a “counter current heat exchange”, which keeps their body  tempreture +/- 7C above the surrounding water temperature. 

  • All sharks have an incredibly unique system on the tip of their nose called the “ampillae of Lorenzini”. These are small pores filled with a gel that transmits the electrical currents in the water to the shark’s brain so that it can assess its environment.

  • White sharks give birth to live young (not eggs), and they give birth to 6-8 pups at one time. Pups are usually between 1.0-1.5m in length and are born with teeth.

  • Body language has been a well documented form of shark communication and has identified body arching, jaw gaping, and other postures as specific social tactics.

Five star whale watching and a Marine Big 5 experience in Kleinbaai, South Africa


Marine Big 5


Dyer Island Cruises is a 5-star award winning boat-based whale watching company located in Kleinbaai. Whether whale watching is a once in a lifetime dream or part of a life-long passion, our 10+ years of expertise provides a superior experience for every client. We specialize in the "Marine Big 5" experience, where we hope to find whales, dolphins, seals, sharks, and African penguins on each trip. Not to mention our incredible seabird sightings (albatross, petrels, skuas, etc) and breath-taking unspoiled scenery - we show you whales and then some!

Safety is our top priority and we spare no expense. Our vessel, the "Whale Whisperer" is custom-designed for boat-based whale watching, safety, and comfort. She is a 11.5m aluminium hull wrapped in pontoons for steady viewing from any side and is equipped with twin 250hp four-stroke engines (the most eco-friendly in the business). She comes with an onboard toilet, two additional decks for viewing, and an open wheelhouse. We limit our trips to an exclusive 20-24 passengers, assuring that each client has ample space on board as well as a personalized service (this means - book ahead!).

Southern right whale viewing season can be as early as June and run as late as early January - depending on whale activity. There is nowhere else in the world where you can travel for less than one hour and see as many as 20+ whales!

From January - May, Dyer Island Cruises runs eco-trips where we visit our Cape fur seal colony (60,000 seals!), a dolphin habitat, as well as venture into the deep sea to find the unexpected!
