First dived in 2021 by Wreckless Divers.

A pretty reef, fairly deep on the sand, but with a fair amount of area above 40 m. Compact, and quite steep sided.

Position

Wreckless Ridge 📍: S34°15.541' E18°33.970'

A fairly small separate granite ridge reef to the southeast of Whittle Rock. This site is not in a Marine Protected Area. A permit is not required.

Name

The site is named after the RIB dive boat Wreckless, which found the reef and was the first to dive the site.

Depth

Maximum depth is about 48 m on the sand, and the top of the ridge is about 30 m. (Average depth of a dive is likely to be about 36 m.

Visibility

The shallower parts of the reef may have good visibility even when the deeper areas are silty.

Topography

The reef lies with its long axis roughly nortwest-southeast. It is about 350 m long and somewhere around 50 to 80 m wide

Geology: Pre-Cambrian granite of the Peninsula pluton.

Conditions

The site is exposed to wind from all directions, so should be dived in light winds and low swell.

The site will probably usually be at it's best in winter but there will also be occasional opportunities at other times when the swell is low.

This is an area which usually has a thermocline in late summer, and may have poor visibility near the surface caused by plankton blooms in sunny weather.

Hazards

There are no known site-specific hazards other than the depth. Most of the site is below the depth range usually accepted as suitable for recreational diving, or for emergency swimming ascent. Surface currents due to wind are likely and may take the divers away from the descent area during an ascent with decompression stops.

Skills

The competence to follow suitable decompression procedures is recommended. This includes carrying and using appropriate gases and deploying a decompression buoy to mark the position of the divers during ascent.

Equipment

Adequate and reliable alternative breathing gas supply, as the depth is beyond the range for which emergency swimming ascent is a reasonable response. A decompression buoy is strongly recommended, and may be required by the service provider. A fully redundant emergency gas supply is recommended. Use of breathing gas mixtures appropriate to the depth is recommended,
