An image of a fishermen's lookout point. A shoal of fish is spotted from an observation post on the hill or a promontory above the bay by the 'uitkyker' or 'wagter'.  Blue water or sometimes light yellow indicated harders, elf gave a bluish tinge; a dark colour showed a compact shoal and an experienced fisherman could estimate the number of fish.  When the spread of colour moved within range of the trekkers, a signal would be given by whistle or flag and the boat with the net piled in readiness in the stern sheets, sets out from the shore with one end of the net secured to the shore by a rope manned by all available volunteers, sometimes even including members of the passing public.
