Diving the Cape Peninsula and False Bay/Klein Tafelberg

Jump to: navigation, search

The dive site Klein Tafelberg Reef is an offshore rocky reef in the outer Hout Bay area on the Atlantic seaboard of the Cape Peninsula, near Cape Town in the Western Cape province of South Africa.

Understand

Map of the dive site Klein Tafelberg.

This can be a spectacular dive in good visibility as the reef profile is very rugged. The depth varies from about 42m to just under 15m over a small area. The reef structure provides a wide range of habitats and there is a large diversity of colourful invertebrates to be seen.

This site is a group of pinnacles at the south eastern end of the large Tafelberg Reef complex, which may extend all the way to Vulcan Rock in the west.

Position

S34°04.442’ E018°19.191’ (Klein Tafelberg pinnacle)

S34°04.443’ E018°19.178’ (Table Top pinnacle)

S34°04.454’ E018°19.232’ (42m sand patch)

This site is in a Marine Protected Area (2004). A permit is required.

Name

The name "Klein Tafelberg Reef" translates to Small Table Mountain Reef, it is a part of Tafelberg Reef complex and is slightly separate from the main reef, at the south eastern end. The alternative names "Salad Bowl" and "Yacht Wreck" refer to the large variety of colouful reef life on the rocks of the bowl shaped hollow in the side of the reef, and the wreck of the yacht that lies in it.

Depth

Maximum is about 42m, and the top of the pinnacle about 14m. The Table Top pinnacle a short distance to the west is at 15m and is much larger.

Visibility

This is an area where visibility is likely to be better than average. On a good day it can exceed 20m, but 10m is more likely. Good visibility is often associated with several days of strong south easterly wind which causes upwelling of clear, cold water from the depths. This water is often rich in dissolved nutrients, and if the wind is followed by a few days of bright sunshine, there may be an plankton bloom, also known as a 'red tide' which may decrease the visibility, particularly in the surface layers. However, the deeper water may still be relatively clear, though the light levels will be less and the water will be much greener.

Topography

The site is a huge granite outcrop with big boulders piled on top, and patches of sand bottom in the deeper areas. The relief is very rugged and spectacular in good visibility. Although most of the pinnacles are not particularly large, many are very steep and precipitous, with deep cracks and gullies adjacent to them, and there are many places where the reef can be seen towering several metres above you, while there is still a significant drop to the local bottom.

There are the remains of a small yacht on a ledge called the salad bowl part way down the north side of the shallowest pinnacle, and below that there are other outcrops to the north.

A short distance to the west, and visible from the shallow pinnacle in good conditions, is a larger flat topped pinnacle at about 15m depth known as the Table Top, as it is roughly square and flat on top with sheer sides. This pinnacle is about 21m long and 17m wide, and is split by a huge crack about 2m wide into two unequal sections. The dropoff to the north east is much deeper than to the south west. The table top is covered by a fairly dense Split-fan kelp forest.

The view up to this pinnacle from the wreck is quite impressive on a clear day, and the near vertical rock face with the big crack can be clearly seen looming above.

About 80m to the south east of the pinnacle there is a sand patch at 42m depth, and to the north the sand is at about 36m

To the southwest the depth drops to 45m in places, still quite close to the shallower parts. There is also an extensive area that is close to 24m deep and fairly flat from south to southwest of the pinnacle.

Conditions

The site is exposed to south westerly swells, which can cause a strong surge. Even a low swell can cause a noticeable surge if the period is long. The site is usually at its best in summer but there are also occasional opportunities in autumn and winter. This is a site where some of the world's largest surfable waves can occur, but it is hard to believe this when conditions are suitable for diving.

This is an area which sometimes has upwellings, caused by strong south easterly winds, resulting in cold clear water, which may develop a plankton bloom over a few days, which will reduce the visibility again.

Keep a lookout for times when the south west swell is low and short period, and there is not too much south easterly wind forecast.

There is often a slight surface current. This is probably caused by wind, but on calm days the direction will be unpredictable until you are on site. It is not generally considered a hazard, but it would be prudent not to spend too long on the surface before descending. If ascending away from the shotline, a DSMB will allow the boat to keep track of your drift during the safety stop.


Get in

The site is only accessible by boat. It is about 4.5km from Hout Bay Harbour.

Trivia

Marine life

Lots of great invertebrates on reefs, also seals, kelp, and some Hottentot seabream.

The tops of the shallower pinnacles are covered by a dense growth of large red-bait pods, and usually split-fan kelp, with an understorey of smaller red seaweeds, like the Coral plocamion, and supporting a variety of anemones, hydroids and other small invertebrates.

Even near the tops of the pinnacles, corals, false corals and sponges are abundant on the steeper rock faces and particularly under overhangs. Basket stars are frequently seen at this site, and there are several other starfish, including the brooding cushion star.

Features

Wreck of yacht just north of pinnacle.

One of the most accessible 40m dive sites in the region, with plenty to see on your way up.

Photography

Good site for macro and wide angle photography.

Routes

Descend on shotline to the reef, swim down to the wreck of the yacht, continue to desired depth, then work your way up the rocks to the top of the pinnacle and deploy your DSMB.

Stay safe

Hazards

Cold water, Nitrogen narcosis in the deeper areas. Strong offshore winds may develop over a short time.

Skills

No special skills are required, but appropriate certification for the depth is expected.

Equipment

It is cold and relatively deep, and a dry suit is recommended. This is a dive site where the use of Nitrox can be worthwhile to extend no-stop time. A compass will help keep you orientated, a light will restore colour and allow you to look into crevices and overhangs, and a reel with DSMB is worth carrying in case you need to surface away from the shot line.
