South Africa is a sports-mad country, with hundreds of clubs and teams, covering a wide range of sports.
Green and gold have been the national sporting colours since 1906. At first, they applied to rugby, but they were later extended to other sports (and, in World War II, they were adopted by the defence force too, as if the war were a sports fixture).
A fair number of clubs and controlling bodies are armigerous. The following is a sport-by-sport selection of arms.
Athletics
Bowls
Several bowling clubs have registered arms and badges. Among them was the Cape Country Bowling Association, whose arms were Or, an aloe plant with three flower spikes proper; on a chief arched Gules a bowling jack Argent between two bowling woods Or (BoH 1967).
Cricket
Cycling
The arms of the Western Province Cycle-Car Association (BoH 1993) incorporate a highly stylised stick figure, and two symbols of the Western Cape, namely the provincial flower and a stylised representation of Table Mountain: Argent, a representation of a cyclist on a cycle-car Sable ensigned of a disa flower Gules; a chief enhanced in each flank a full and a half peak to base the half peaks against the respective edges of the shield Azure.
Jukskei
Rowing
The arms of the Vaal Rowing Club (BoH 1966) are Quarterly Gules and Argent, two oars in saltire handles to base Azure.
Rugby
Sailing
Many sailing and yachting clubs have registered burgees or pennants. You'll find a selection on the Flags of the World website.
Soccer
Soccer is probably the most popular sport in South Africa, so much so that several English and Dutch clubs have established South African teams. Many clubs have quasi-armorial badges, and a few have registered coats of arms, including the well-known Orlando Pirates (BoH 1973): Sable, a skull and crossbones within an orle Argent. Evidently, there is also a version of the arms which has the name on the shield.
