Depth

Maximum depth on the sand is 35 m, top of wreckage and nearby reef generally below 30 m

Topography

The vessel was about 40 m long but the main section of wreckage is now only about 20 m as the bow and stern sections were blown right off when scuttling it. The midships section lies moderately intact and upright on a narrow strip of sand at 35 m. There is a reef of huge boulders with some great reef life to the north and a pinnacle which rises to 13 m is fairly close by to the south. Unfortunately the superstructure and funnels are gone and much of the hull has filled with sand. The nearby reef to the south is low profile, not much more than a metre or so above the sand. The bow section is said to lie about 60 m to the southwest of the main wreckage, northwest of the Plan B pinnacles, at about 30 m depth. There is a stockless anchor near to the midships section on the reef, to the south, but the exact position is not known. The wreckage of the bow structure is scattered around the reef, with no large pieces.

Geology: Sand bottom with outcrops of granite reef of the late Pre-Cambrian Peninsula pluton.

Conditions

The site is exposed to south west and north west swell end winds, but is reasonably sheltered from south easterly winds. The site is diveable in low to moderate swell height as long as the wave period is short. The site is usually at it's best in summer but there may also be occasional opportunities in autumn and early winter.

This is an area which sometimes has upwellings, caused by the south easterly wind, resulting in cold clean water, and which may be followed by plankton blooms, which will reduce visibility again.

If the south-easter blows strongly, the trip back will be wet and uncomfortable.

Get in

The site can only be reached by boat. It is about 7.5 km from the slipway at Hout Bay harbour.
