Hey Patrick
I haven't personally been there, but i've heard that its at Monwabisi, apparaently there are three spots there, Eerste Baai, tweede Baai and then Swartlip. Tweede Baai is renowned for big Kob as the water is quite deep. Im not sure whether you can launch anywhere there, perhaps someone else can shed some light on this.
For the past month or so, i've heard of good fish coming out at Tweede Baai. Think we need to get tailfin to guide a bunch of us out there for a day, as its one of his favourite spots.
