At its shallowest point, Tartar Bank rises to within 45 feet of the surface from depths of 3,000 feet or more. You almost always find flocks of birds following tuna schools around Tartar, and marlin often follow the tunas. But of all the hot spots around southern Cat Island, I like Columbus Point the best. As in many other parts of the Bahamas, a shallow finger of submerged reef juts out several miles from shore at Columbus; being on the eastern side of Cat, only open ocean lies to the east. The currents flowing by the point bring an incredible amount of life to the area most days, including big tuna schools, birds, whales and, of course, marlin.
