Reef dive. Boat access only. Depth 40 m to about 55 m. This site is not in a Marine Protected Area. A permit is not required.

The site is deep reef, and south of Whittle Rock.

Maximum depth is about 55 m at the sand to the north and the top of the pinnacle is at about 40.5 m. Average depth of a dive is likely to be about 45 to 50 m, excluding ascent. Expect decompression stops.

Visibility can be very good, but probably not that often. Nobody knows yet.

The reef is a fairly large expanse of Peninsula granite corestone surrounded by sand. The central area around the high point is a large, moderate profile outcrop, split into ridges and gullies, some with sand bottoms up to 45 m depth. Depth at the surrounding sand is reported as 55 m to the north, and 53 m at a sand tongue to the south, with more reef on the other side.

Geology: Granite corestone outcrop of the Pre-Cambrian Peninsula pluton.

Boat access only. The site is about 16.9 km from Simon's Town Jetty, or 10 km from Miller's Point slipway

Just the depth.

The ability to deploy a decompression buoy, and follow a decompression schedule appropriate to the dive profile, and this is a site where trimix is recommended for the deeper parts.

This is a relatively deep dive. Carry enough of appropriate gases to allow safe decompression. A DSMB is strongly recommended, as is a suitable trimix for breathing gas.
