We took a two hour taxi trip to Gansbaai for our shark dive. They have custom built boats with shark-dive cages that attach to the side of the boats.
On our way out, somehow they caught an octopus. Pretty cool to touch, they have some pretty strong suction things on their legs.
This is Dyer Island--there are two islands, one with seals and one with lots of birds and a research station (I am not sure which one is actually Dyer Island.) There were tons of seals on the island and playing in the water.
This is the island with all the birds and the research station. I guess they have people that scare the seals away from this island so that they don't smash all of the bird nests--which is why all of the seals are on the other island.
The water in between the two islands is known as Shark Alley. So, that is where we anchored and waited for our sharks to come.
They attract sharks with some tuna as bait and a 'dummy' seal made from a kick board. They also have a guy in back mixing some 'chum' that is made of blood and guts of fish. I hope that guy gets paid well, it smelled disgusting. You can see a shark fin just above the dummy seal.
Once the sharks are attracted, you put on a wet suit and mask and jump in the cage. The cage can hold 7 people at a time. The cage is 1/3 above the water and 2/3 under water. When the shark spotter see's a shark he hollars and you go under water holding your breath to see the sharks. That day you could see about 3 meters into the water, which some said was pretty good. Here a shark came up close to the cages.
The shark spotter said that we saw three 3-meter sharks and two 2-meter sharks. I guess that is pretty good for this time of year. They said that May is the best month to see sharks in this area.
Remember to keep your fingers and toes inside the cage at all times! Here the shark is attacking the bait right by the cages.
