Navigational beacons

One of the shipping beacons out at Cape Recife. In addition to the lighthouse there are also two beacons that were used in the early days to guide the ships into Algoa Bay before the advent of modern navigational equipment. Ships sailing along the southern coast towards Algoa Bay had to stay on a straight coarse until they lined up the two beacons. Only then was it safe to turn into the Bay and avoid running aground on the treacherous Thunderbolt Reef.
