Sidemount Systems


Sidemount is a technical gear configuration utilising twin scuba cylinders worn on either side of the body. It was originally developed by and for cave divers as a way to slip in and out of confined spaces. The side mount configuration is also becoming popular with wreck divers, rebreather divers and even sport/recreational divers.

Black Rock Jetty, Half Moon Bay
Black Rock Jetty | © Unknown

Depth: 2 m (6.56 ft) to 8 m (26 ft)

Level: Open Water and beyond.

Ideal Conditions:
Best dived when the wind blows from the north-west, but good in anything but a southerly. Avoid during a southerly as the area can get quite choppy. Just before the high tide will give the clearest water. See WillyWeather (Black Rock) as a guide for the tide times and the height of the tide.

What To Expect:
Black Rock Jetty in Half Moon Bay, Port Phillip, is a good site for new divers. Around the Black Rock Jetty are small leather jackets, starfish, gobbleguts and the occasional seahorse. The underwater terrain varies from jetty pylons to rocky reefs to seagrass beds. You'll have all kinds of company, including sea urchins, anemones, nudibranchs and (poisonous) blue-ringed octopuses.

Half Moon Bay, home to the Black Rock Yacht Club and the Half Moon Bay Lifesaving Club, is the crescent-shaped small sandy shallow area to the left of the car park. It is an excellent night dive especially in spring when the phosphorescence is at its brightest. At night you can find octopus, flathead and bull rays.

First proceed from the shore under the jetty out to the end. Then take a heading west and cross the sand plains in a depth of about 5 to 6 metres. You'll find the bottom of a reef in a depth of 3 metres. Follow the reef around the point. Exit up the western beach.

Parking:
You can usually park in the car park, but it fills quickly on nice days. Parking is metered so get a ticket.

Dive Entry:
Enter the water down at the ramp and dive out under the pier. Always take a dive flag!

Also worth a note is the historic protected shipwreck of the HMVS Cerberus warship. Divers are banned from the 0.5-hectare rectangle protective zone around the wreck. It's also too dangerous, so please keep a distance away. The guns from the warship lie on the sandy bottom nearby.

DISCLAIMER: No claim is made by The Scuba Doctor as to the accuracy of the dive site coordinates listed here. Should anyone decide to use these GPS marks to locate and dive on a site, they do so entirely at their own risk. Always verify against other sources.

The marks come from numerous sources including commercial operators, independent dive clubs, reference works, and active divers. Some are known to be accurate, while others may not be. Some GPS marks may even have come from maps using the AGD66 datum, and thus may need be converted to the WGS84 datum. To distinguish between the possible accuracy of the dive site marks, we've tried to give each mark a source of GPS, Google Earth, or unknown.
