Diving the Glencairn Barge
The dive site Glencairn Barge, Quarry Barge, or Cement Barge is an offshore recent wreck on a rocky reef in the Glencairn area on the False Bay coast of the Cape Peninsula near Cape Town in the Western Cape province of South Africa.

Position
editName
edit
The name "Cement Barge" is derived from the wreck of a small barge at this site, said to have been used to transport cement, but more probably used to convey rock from the quarry to Simon's Town. The alternative name "Glencairn Barge" refers to the suburb Glencairn, off which it lies, and "Quarry Barge" refers to the quarry it served.
Depth
editMaximum depth is about 14 m and the top of the wreckage is about 12 m.
Topography
editLow sandstone reef with sandy patches. The wreck lies on the edge of the sand.
Geology: Sandstone reef probably of the Peninsula formation or possibly the underlying Graafwater formation.
Conditions
editBest dived in a low swell. This is more important for shore entries, when an onshore wind will make entry and exit tricky, and an offshore wind could make the trip back very tiring if done on the surface.
The site is usually at it's best in winter but there are also occasional opportunities in other seasons.
Facilities
editPaved off-road parking at the whale lookout is usually adequate.
Get in
editBoat dive or shore dive with a long swim. Access and entry/exit for shore dive as for Quarry.
The site is about 4.0 km from Simon's Town jetty, or 8.8 km from Miller's Point slipway.

editMarine life
editReef life is predominantly feather stars and sea cucumbers, with significant presence of large sea squirts. A moderate range of fish may be seen, largely cryptic species, like Klipfish and Redfingers.
Blue spotted klipfish
Seacatfish are more likely to be seen at night
Cuttlefish
Sea fan with nudibranch and eggs
Burrowing anemones
Features
editSmall wreck of a steel barge. The hull is intact and lies upright on a sandy patch between the reefs. Two holds are open to access from above and the overhead around the sides is trivial.

editRoutes
edit- Shore dive: Swim out on the surface using a GPS to find the position. Dive and find the wreck, then work your way back to the shore using compass navigation. Allow enough air for a 500 m swim on the return. The water shelves gradually toward the shore and there should be no danger of requiring decompression
- Boat dive: Put down a shot-line or anchor at the wreck There are few useful landmarks on the reefs, so it is easy to lose the wreck if you move away from it, so a live-boat dive is convenient for the divers.
Stay safe
editHazards
editEntry and exit may be difficult in an onshore wind, and the return swim could be tiring in an offshore wind. This area may be on the summer cruise route of the local Great White shark population, but this is hypothetical at this stage.
Skills
editNo special skills required on boat dives. Good fitness and ability to navigate with a compass are required for shore dives.
Equipment
editA compass is essential for shore dives to navigate back under water. A deployable SMB is convenient when doing a boat dive. On night dives a light on the shot line will help divers find their way back if they move away from the wreck and can’t find it again.
