Weekend in the Tsitsikamma

[REEFMAN]

Looking at the pic attached...

Yellow ring represents shallow water - defined by the difference in colour. Probably a sandbank. White water on top from water churning as it becomes shallower. This churning up of the sandbank will release food into the water for baitfish, which will gather to feed. White water on top provides some shelter too. Red crosses are where predators eg Kob would wait in ambush.
White X marks a deep trough, between the sandbank and more churning water close to the rocks...
Beyond the yellow circle is more deep water... bigger predators will be feeding on the other side of the dropoff, but demands a good cast out beyond the bank.
Not to mention the dropoffs around the rocky point... reef fish haven... 

Well that's what I see anyway...

Thanks RM! So if my understanding is correct the white crosses (trough) may not be productive.

That is a good read from the photo Reefman, but if you are actually standing there, you will notice the difference.

The sandy patch is actually the only break in an otherwise completely rocky bottom, in other words, the deeper patch of water.  The white water on the surface is caused by a rip coming off the rocks through this channel. 
 
I would rather cast into the channel leading out of the gully, or the channel at the back itself.  Either way, still a brilliant spot.
