Super Natural

Hmmm, well this is an interesting question Gerrard7. I've wondered about this myself. Many believe that it's all hooey. That the ocean is just particularly turbulent there, as a result of sub-surface currents. Others swear that there is some phenomena behind the lore of the area. I've never been there myself, so I'm certainly no expert. However, the lore intrigues me. The oceans are still such a great mystery. If I had to put forth an explanation, uninformed as it were, I would suggest that the ocean must be particularly deep there. That there must be the remains of some sort of volcano deep below the surface, since islands are formed as a result of volcanic activity. And, that the strange current shifts must be due to water heating and cooling, while also experiencing vast movement into and out of large volcanic caverns. I think it would be intriguing to test my theory. If there's any validity to it, the caverns would probably be impressive beyond belief. I'll be curious to read the other responses you get to your question. Very intriguing question!
