Hi Peter,
Try Silversands in Betty's bay for spotted gullies in small swell using mullet baits. You can also try for white steenbras in Betty's Bay beach breaks such as Verwoerds and Silversands in small seas. Larger surf will require you to target galjoen on Betty's Bay reefs where flat rocks with eel grass and no kelp will hold fish.
Cape Point reserve is also a good option for either inshore boat fishing at the point for yellowtail, snoek and hottentot and Buffelsbay for snoek and chokka. The Reserve also offers good shore fishing for galjoen in large seas with same rock structure as mentioned for Betty's bay.
Provincial R&S guys held interclub at Struisbaai last weekend and were still able to catch raggies, bronzies, greys and kob. Galjoen and Steenbras will feature prominently at places like Brandfontein, Rietfontein and Suiderstrand in that area.
Hope this helps...
