The site was named "Dreadlocks Reef" after the Dreadlocks hydroids found there in unusually large numbers.

Depth

Maximum depth is about 20 m. and the top of the pinnacle is about 1.5 m deep at low tide. (Average depth is likely to be about 12 to 15 m)

Visibility

Visibility will depend on weather conditions, and may be in excess of 15 m on a good day after an offshore wind and upwelling.

Topography

Large corestone ridge with low surrounding reefs. The pinnacle is quite pointy, and the tip is only a couple of metres across. Ridge axis bearing 300°T (324° magnetic), ridge length 50 m and width 20 m at 12 m deep. Length at bottom about 100 m, width not known, but probably about 40 m at widest. There is a smaller pinnacle a few metres to the south about 10 m diameter at 12 m depth.

The SAN charts indicate another high reef about 200 m to the north-east of Dreadlocks pinnacle, but this has not yet been mapped.

Geology: Pre-Cambrian granite of the Peninsula pluton.

Conditions

The site is exposed to westerly winds and swell.so should be dived in calm or offshore winds, when the swell is low, and is often good in South Easterly winds. The site is reasonably protected from easterly seas.

The site is usually at its best in summer but there are also occasional opportunities at other times of the year.

This is an area which sometimes has upwellings of clear cold water, caused by offshore winds, resulting in good visibility and low temperatures, sometimes followed by algal blloms which will reduce the visibility again.
