The searching continued, there were some pleasant distractions along the way as we spotted a Sunfish and some seals but what we really wanted were some baskers. Finally we found a fin and then another one, and then another. Charles positioned Logan about 100 yards ahead of he sharks and we all slid quietly into the water and waited. Soon enough the sharks appeared out of the green murk and disappeared as quickly as they came and kept circling us for several minutes.
Charles advised us that the trick with the sharks is to keep fairly still on the surface and let them pass you, if you make too much noise or move too quickly they are off. It is a balance of sticking your head out of the water to locate the dorsal fin and then getting your head down back under water and waiting for the shark to appear.
There were a couple of occasions, just when you think the sharks have gone, one suddenly appears from behind or the side, the first time it happens it is a little unnerving but a great experience.
We spent about 2 -3 hours in the water with sharks towards the end of the day, they weren't always cooperative and we were jumping in and out of the RIB to reposition ourselves as the sharks moved along the coast, which in itself is pretty tiring, especially if you have too much weight on your weight belt!!
I was using my 5D in an Aquatica housing with a Canon 15mm f2.8 fish eye lens and an 8.5" dome port. This was great for getting the whole shark in view but i found myself wanting a bit more zoom. I switched half way through the day to the 17-40mm f4 L and had was able to zoom in a bit but the murky water meant that the only way to get really clear shots is the old underwater adage, get close then get closer!
We drove home via McDonalds and eventually walked through my front door at 12:00 so it was a pretty long day, but it was certainly worth it. I am looking forward to repeating the trip next year.
