Speaking of currents, remember that shark week episode with the sharkman Manny I think is his name, anyway, this guy would swim with different shark species and that was on the show, bulls, tigers, etc...
Well, he wanted to swim with a mako, and so they went to Venice. That's Venice, Louisiana for those of you that are curious.
Anyway, it was Manny, the photographer and some chick in the water together. After a few days they had about a 6'er come in. They went out with camera and feed and the shark came right up to them.
The PROBLEM came when they ran out of feed and the shark was still very hungry, and while trying to get back to the boat, the current changed, in a very extreme way.
So here they were trying to get back to the boat, struggling like mad cause the current was so wicked and the shark was right on their heels. It was a very real situation. They couldn't turn their backs cause the shark was right there, and it was hard to swim if they didn't, it was quite a struggle, but they made it back by the skin of their teeth!
I watched this show with my noonie in my mouth, I had goosebumps brother!
