Diving the Cape Peninsula and False Bay/Fan Reef
The dive site Fan Reef is a small offshore rocky reef in the Castle Rocks area on the Cape Peninsula side of False Bay, near Cape Town in the Western Cape province of South Africa.
The site has a large concentration of Gorgonian sea fans
Access to this site is only by boat. The distance from Miller's Point slipway is about 1.8km.
The site is about half way between Miller's Point and Castle Rocks and is on the 30m depth contour. It is about 1.1 km from the shore directly to the west. North Fan Reef is about 100m to the north of Fan Reef across the sand.
This site is in a Marine Protected Area (2009). A permit is required.
The reef is named "Fan Reef" for the large numbers of gorgonian sea fans found there.
The bottom is at about 30m on the sand to the east of the reef
Fan Reef: Small isolated granite corestone reef, Large outcrops, some rocks quite high, some low. Reef area more or less contiguous.
North Fan Reef: Granite reef of outcrops and boulders of about 10m maximum height, and up to about 20m long. Rugged terrain, with lots of gulleys and steep walls and quite a few overhangs. There is a small swimthrough probably on the west side just above the sand.
Geology: Granite of the late Pre-Cambrian Peninsula pluton
The site is moderately protected from south westerly swell. South east chop may make it unpleasant on the surface, but it may be quiet below the wave base. Generally considered a winter dive site but there are also occasional opportunities in autumn and spring.
Notable for a variety of sea fans, Sunburst soft corals, striped and strawberry anemones, Basket stars, feather stars, and sea cucumbers, coralline algae, encrusting sponges, urchins, colonial ascidians and a few species of nudibranch.
(photographic equipment suggestions)
No routes recommended, the reef is quite small and may be comprehensively visited on a dive.
No site specific hazards have been reported.
Appropriate certification for the depth is expected. No special skills are required, though bouyancy control and finning skills should be adequate to avoid damage to the sea fans and other sensitive organisms.
No special equipment required. A DSMB and reel are recommended.
