### Position

-33.8818318.3385831 MV Gemsbok: S33°52.910' E18°20.315'
This site is in the Robben Island Marine Protected Area since 2019. A permit is required.

### Name

The 39.2 x 8.3 m 314 grt single screw buoy tender MV L M Gemsbok built 1965, capsized and sank about 4 km from Green Point Light house on 2nd September 1975 while transferring an anchor chain of a cargo vessel. The chain snagged and the weight of the chain caused the vessel to capsize and sink within minutes. The wreck lies on its starboard side.

### Depth

Deep dive: Maximum depth on the wreck is about 57 m on the sand, and the top of the port side is about 50 m. Average depth of the site is likely to be about 54 m.

### Visibility

Visibility is unpredictable, and is not necessarily indicated by surface conditions. In December 2019 visibility exceeded 20 m under a 6 m layer of plankton bloom one weekend, and the next weekend it was less than 2 m all the way down, and almost totally dark at the wreck.

### Topography

The wreck is substantially intact, with the mast still in place. There are a few places where hull plating has wasted sufficiently to break through. Th wreck lies on the starboard side on a fairly flat sand bottom with the deck almost vertical. The propeller is still in place on the shaft and there is a gantry mast and bow gantry still in place A large hatch on the foredeck gives access to part of the interior. The port bow anchor is in the hawsepipe.

Access to this site is only possible by boat, usually from Oceana Power Boat Club slipway at Granger Bay.
There are day charter boats which can take a diver to any of the dive sites in the region, but most operators only work from a limited number of launch sites, which limits the dive sites they visit. Visits to a dive site also depend on the weather and are generally not predictable or bookable more than two to four days in advance. See the listing for Cape Peninsula and False Bay boat dive charters and the associated services directory for contact details.
