Great White from the topside of the boat

I've posted a lot of video of crazy folks swimming with great white sharks, so I thought it would be interesting to see how people react when they see a great white suddenly appear next to their boat.

Here's such a video. Now, I don't know where this was shot. The description says that this was shot in the outer banks of North Carolina, but I seriously doubt that; the water is just too blue.

I'm also wondering why the shark is staying so close to the boat. I'm not seeing any chum or anything. I'm thinking this must be in Mexico or somewhere where these sharks congregate in large numbers.

Oh, the video say that it came from Poacher Sport Fishing. Visit the site and there is no mention of a great white spotting, but they do talk about their location in the outer banks.
