I am surveying and mapping the dive sites of Cape Town as a long term project. Wikivoyage is how I make this information available to the public on a constantly updated format.
Most of the surveys are done by towing a surface marker buoy on a tight tether along a chosen contour, then after the dive I download the GPS track and transfer it to Inkscape and trace around it to show the shape of the site. A similar process is used for the outlines of reefs and wrecks, and some details are simply measured and sketched on site. On rare occasions the visibility is good enough to use photos and video to provide details.
Since March 2011 I have had access to unpublished data from the SA Council for Geoscience which did a sidescan sonar survey and fascies interpretation of parts of False Bay and the Atlantic seaboard of the Cape Peninsula for a reef ecology monitoring project. This data lacks detail of depth and can be difficult to interpret with precision, but it is excellent for identifying roughly where all the rocky areas are. However it is limited to places where the sonar fish is not likely to hit rocks, so there is still plenty of reef that has to be identified and mapped in other ways in the close inshore zone, Also it does not give depth profiles. The main value is that it is possible to be reasonably sure that most reef has been identified in these zones.
Most of the boat access sites were mapped from Blue Flash charters boats, as Blue Flash caters largely for a fairly regular clientele of advanced local divers, and is more inclined towards exploring new areas and opening up new sites, and a moderate number from Dive and Adventure and Pisces Diving boats. The owners support this project by allowing me a special rate for boat dives. The shore dives were done under my own power, usually alone, but sometimes with a few buddies who are prepared to swim along with me while I survey.
I would welcome participation from other local divers, but so far I have been unable to persuade any of them to actually go out and survey.
I was made an admin on Wikivoyage during the migration, and it seems to have stuck. I am available to help with admin type tasks when needed, but tend to concentrate on dive guides and related articles, where this level of access is not needed very often. I also make an effort to keep up with any policy discussions and decisions.

My home turf is the Cape Peninsula and False Bay, in which region I have logged well over 1000 dives at a large range of sites, some of which I have mapped. I am not currently affiliated to any recreational diving certification agency, nor employed by a dive shop or dive charter business.
- Docent for:
- Admin since being conscripted during the migration.
- Please feel free to ask me any questions about these topics and I will try to provide a useful answer.
The first and main project: Diving the Cape Peninsula and False Bay
I would also like to extend the range of dive sites to other parts of the country, preferably with collaboration from divers who live in the areas.
- (WT-en) List of Dive sites in the project
- The regional dive guide Diving the Cape Peninsula and False Bay has been promoted to star (28th November 2010)
Dive sites with star potential: — to be upgraded at about 1 site per season (summer/winter)
- Diving the Cape Peninsula and False Bay/Smits Reef
- Diving the Cape Peninsula and False Bay/Coral Gardens (Oudekraal)
- Diving the Cape Peninsula and False Bay/Justins Caves
- Diving the Cape Peninsula and False Bay/Geldkis
- Diving the Cape Peninsula and False Bay/Strawberry Rocks

- Diving the Cape Peninsula and False Bay/SS Clan Stuart
- Diving the Cape Peninsula and False Bay/SAS Fleur
- Diving the Cape Peninsula and False Bay/Atlantis Reef
- Getting Scuba diving up to star standard.
- Creating Diving in New Zealand and getting the main article up to usable status.
- Creating regional articles for Diving in New Zealand for regions from Three Kings islands through Bay of Plenty
- Creating site articles for sites that I have dived in NZ.
- Diving in South Africa is intended as an article between Scuba diving and local diving guides for South Africa.
- Assisting with Diving in Hermanus, Diving the Tsitsikamma, Diving Sodwana Bay, Diving Aliwal Shoal and other regional guides
- Developing and standardising structure for continental, national and local level diving guide articles. Producing templates where they may be useful. Editing diving guide articles to get them to fit the current structure, and hopefully not offending too many past contributors to these articles.
- Providing help articles on how to create and edit dive guide articles.
More or less finished and maintenance projects

- Maintain Diving in Thailand
- Maintain Dive sites of Saipan
- Maintain Diving in Sweden
- Maintain Diving in the Philippines
- Developing Dive Guides for the whole of South Africa with the collaboration of divers in other parts of the country. Unfortunately, to date (July 2010) have had no input from other parts of the country.
- Update (October 2010): Some inland sites are now available, and Diving in Durban is based on the work of Bryan Hart of Durban Undersea Club.
- Eventually extending this system of Dive Guides and Dive Site descriptions to other parts of the world. This will have to be done as a major collaborative project and will necessarily involve input from hundreds of divers. Today, Cape Town, Tomorrow, ze Vorld! Ahahahahaha!!!!!!!!!.... Should keep me busy indefinitely.
