Hookah Diving Systems


The Scuba Doctor has an excellent range of complete Hookah diving systems (also known as Surface Supply Diving Systems). Hooka dive systems are an alternative to tank based scuba diving and allow descending underwater for extended periods of time with air supplied from the surface.

Hookah diving systems typically consist of a battery or petrol-powered air compressor that delivers air, through a long hose called a down-line, to the diver under the water. Hookah diving does not require the use of a BCD or a first stage regulator. Divers wear a harness, which is the attachment point for the down-line and optional weight belts. Divers use a second stage regulator that's specifically designed for use with a hookah system. A traditional scuba regulator will not work.

Hookah Dive System Types

There are two types of hookah dive systems: Dynamic and Static. A Dynamic system uses an air compressor to deliver air at the correct pressure. It has a holding or air reserve tank that provides constant pressure. As the air leaves the tank, more air is added to maintain the pressure. The compressor can be fixed or floating, and petrol or electric. A Static system uses a cylinder of compressed gas (often a scuba tank) as the air source.

A fixed compressor is placed on a dock or on a boat while in use. Floating means that the air source is on a floating platform that the diver pulls along with them.

Petrol vs Electric Hookah Dive Systems

Hookah systems are available in both petrol and electric-powered versions. Petrol systems typically power a higher output compressor, allowing one or two divers to dive and breathe easily. Most commercial hookah diving systems are petrol systems. Petrol systems do require more maintenance than electric versions. They're also a bit louder.

The more 'green' electric systems require less maintenance than petrol systems. They can be recharged on the boat, are quiet, easy to start and less prone to corrosion.

Electric units are more suited to families and fun, plus boat owners wanting to do some underwater maintenance at shallow depths. The petrol units are better suited for cray (lobster) and abalone hunting, plus commercial diving applications.

Please read Introduction to Hookah Diving for more information about things you need to consider with a hookah diving setup.

Depth: 2 m (6.56 ft) to 6 m (20 ft)

Level: Open Water and beyond.

Katie Cove (aka Bunbury Pools and The Bunburys) ia a shore diving and snorkelling site located off the Esplanade at the end of Cole Street, Williamstown. Katie Cove lies between Williamstown Beach (to the west) and Point Gellibrand (to the east), facing south-west into the northern end of Port Phillip. It has an easy shore entry and exit and there are lots of critters to see. It's also close to the Melbourne CBD and while fascinating during the day, also makes for a pleasant night dive.

Diving and Snorkelling at Katie Cove, Williamstown

Walk across Hatt Reserve, down the embankment to the shore, enter the water and head south-west. There is a small pointed rock showing the entrance to the cove, but it may not be visible at high tide. Proceed on the surface out to the right, keeping the pointed rock on your right hand side.

While on the surface, look back towards the opening and get a shore reference for your return journey. Once you are out of the cove the reef drops down to 3 metres. Head south-south-west and it will take you over three reefs and down to 5 to 6 metres deep. Keep an eye on your air consumption to ensure you have enough for the return journey.

There can be plenty of boat traffic so always tow a buoy with a dive flag displayed.

Parking: There are car parks off the Esplanade between Giffard Street and Thompson Street, Williamstown. There is also roadside parking along the Esplanade. Of course, getting a car park is problematic on busy days in Summer. Before gearing up check out the water. If you see lots of white water, head on home.

Facilities: Hatt Reserve features a playground, BBQ, pavilion, toilets, and water tap nearby.

Warning: Always go with a buddy and carry a dive knife. Make sure you tow a dive buoy with dive flag.

Entry/Exit: Shore entry from the shore fronting Hatt Reserve, opposite the intersection of the Esplanade and Cole Street.

Ideal Conditions: There is little background swell in this part of Port Phillip — the water is calm when the wind is still. In moderate winds the waves are choppy and under 0.5 metre. Best with light to moderate offshore northerly to easterly winds, or light onshore south-easterly to north-westerly winds. Not diveable in strong southerly winds. Avoid after rains due to the rain runoff reducing viability. Though high tide is ideal, you are able to dive at Katie Cove on any tide. See WillyWeather (Williamstown Beach) as a guide for the tide times and the height of the tide.

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.
