  • 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.

We had some amazing weather on the boat today which gave everyone great tanning time in between shark sightings! The first trip offered some slower sharks, however the sting ray offered a brief appearance once again to shake things up! We had some very entertaining young girls on board who were more than willing to sing the sharks to the boat, at times I thought I was on a karaoke trip. It actually worked; Great whites really do love Barry White’s music! Our second trip offered a great experience, however my French speaking ability needs to improve dramatically! German, English, Italian and Afrikaans just aren’t cutting it anymore :)! It was a nice day...

The sharks were on South African time today! On both trips they seemed to be a bit sluggish (maybe a heavy night for them), however it didn’t last too long! It took a massive sting ray arriving on the scene to break the silence! It was incredible to see several sharks on the portside right next to a huge sting ray! The smaller sharks seemed to be intimidated by the large ray! It was the first time that I have seen the “Great White Shark” being bullied! I am proud to say that several of our guests conquered their fears of these majestic animals; some even shed a tear because they realized how great these guys are. Let’s see what tomorrow has in store for us!

We were the only shark cage diving company to go out today, which was great! We had the whole area all to ourselves. The conditions were forecast to be bad; however our experienced crew monitored the sea and saw that the conditions were turning into the perfect day! We had brilliant weather on the boat today; the weatherman sometimes gets his predictions wrong! There were an abundance of sharks in the water, the majority were relatively young individuals with lots of energy. Many of our guests were sad to leave, but unfortunately all good things must come to an end! There is always next time...

An amazing sighting today! We were fortunate enough to catch a glimpse of the infamous “Slash Fin”! This large 4.2 meter shark is the reason why our shark boat is named Slash Fin! He has really grown very large over the years and it was great to see him today. There were some big swells at times today, which caused some of our passengers to suffer from “motion distress”! Luckily the crew was there to help them get over their little problems and plunge them into the cage where their minds could be kept busy by majestic sharks! It was great to have a dolphin sighting again today, they are very playful creatures! Our gannet population was out in full force today where they had found a school of fish that were easy pickings off the coast of Dyer Island! Great stuff...
