Abstract


The newly completed fishing and recreational harbour at Port St Francis, on the south-east coast ofSouth Africa, has a 220m outer rubble mound breakwater and an inner revetment, both protected by Core-locĀ® armour units. This paper briefly discusses the breakwater layout and armouring design, the effect of severe storm conditions during construction, and the performance of the Core-loc armouring, as based on the results of photographic monitoring, crane-and-ball profile surveys, visual observations and diver surveys below water.
