S34°10.924’ E018°27.899’ (North Rambler Rock) S34°11.011’ E018°27.918’ (South Rambler Rock)
A reef south east of the Roman Rock lighthouse off Simon’s Town Harbour. It is marked on the SAN charts which show two major groups of rocks at this site: The north group and the south group.
This site is in a Marine Protected Area (2009)
This site is only accessible by boat. It is about 3.9 km from Simon’s Town or 5.4km from Miller’s Point.
This site can be dived at any time of the year that has low or short period swell. Poor visibility at the surface does not necessarily extend to the bottom. The site is exposed to winds from all directions, which can produce an unpleasant choppy sea, and make it difficult for the boat crew to see a diver on the surface. The site is usually at it's best in winter and spring.
Maximum depth about 22m on the sand. Top of reef is about 10m.
Granite of the Pre-Cambrian Peninsula pluton
Very large boulders and outcrops over a fairly small area (About 75m East to West, 35m North to South), coarse sand bottom, a few outlying outcrops of smaller size.
(description needed, please help)
A Great White shark has been seen at this site.
No special skills required, though the ability to deploy a DSMB is useful as most dives are from a live boat.
This is a good photographic site. (photographic equipment suggestions)
A light is useful to restore colour at depth, a compass to keep track of your movements, a DSMB to let the boat know where you are surfacing, and Nitrox can extend no-decompression time significantly in this depth range.
Marine life (and features)
The rocks are encrusted with a variety of organisms depending on depth and orientation. There is kelp and sea urchins on the tops of the pinnacles, and Red-bait and other large solitary ascidians scattered around. The steeper sides are largely covered by common feather stars, There are also occasional sea fans, some quite large. The sand is coarse and shelly near the rocks, and there are sand stars, brittle stars, sand slugs, cerianthids and purple sea pens on the sand.
