Cage Diving - General information

Great White Shark cage diving tours
Location
Dyer Island is a small rocky island close to the fishing village of Gansbaai, on the Southern Cape coast of South Africa. The boat actually leaves from Kleinbaai; this is just outside the town of Gansbaai.

Gansbaai is a two-hour drive away from Cape Town (180km).

How the day starts
We meet at 08h30 (depending on the tide for the day) for breakfast, after breakfast a short briefing about your trip out at sea and by 09h30 the boat launches

The day at sea
Arriving at the anchoring spot in 20-25 minutes. The anchor is put down, the cage goes into the water, a scent trail is laid and we wait for the sharks too arrive.

The rest of the day is spent watching, cage diving and enjoying the day. The trip out at sea between 4/5 hours.

The Cage Dive

Great White Shark cage diving tours
The cage is suspended on the surface of the water right next to the boat. Once the sharks arrive and feel comfortable with the boat and cage in the water, the first divers get dressed into (5mm wet-suits, hoody, bootie, mask and weights) and slip into a 4 man cage, ready to see these magnificent animals face too face.

For most of the year operators cannot make use of air or snorkel for some reason the sharks seem nervous of the bubbles coming out from the regulator.

The dive master standing above you on the boat, will let you know when the shark is within your viewing range to hold your breath and go down, your head is just below the surface of the water.

GREAT WHITE SHARK - general information
Carcharodon Carcharias

Great White Sharks are a protected species along the coasts of California, USA, and Australia and have been a protected species in South Africa since April 1991.

They average between 3.5 - 4.9 meters. Females are larger than males as with most sharks.

Scientists believe that White Sharks give birth to 2-14 pups and are around 1, 5 meters long The eggs are fertilized and hatched within the female and are nourished by eating unfertilized eggs and smaller siblings in the womb. They have no placenta so the babies must fend for themselves, before birth. No maternal instincts are shown they swim away immediately after birth

Great Whites use their powerful tails to propel themselves through the water. The fins are only used for balance. They need too stay moving as they will sink, they have no gas filled bladder to keep them afloat, they are heavier than water and their large oily liver provides some buoyancy. White Sharks cannot swim backwards. To do this they first need to stop swimming, fall backwards to propel themselves backwards.

Great Whites swallow their food whole, their teeth ripping prey into mouth sized pieces. Sea lions and seals are part of their diet.

The life span of the great white is not yet known.
