The prawn at Geelbek are mostly the pink/yellow sand prawn.The mud prawn you will find north of the yacht club,but at full high tide you have to be as tall as Brett Jacobs...lol
I think that with Spring ,you should be able to pump as from 11h00 on Monday....you would need fresh/alive big prawn to get good catches.If possible,then the best solution is to pump the day befor...either in Langebaan or at spots in Cape Town...pumping at high tide will not be feasable.
