Blue Water Desalination's current South Pacific dealer page identifies Manna Marine in Mandurah as an Australian dealer.
Service area: Mandurah and Western Australia
Blue Water Desalination's current South Pacific dealer page identifies Manna Marine in Mandurah as an Australian dealer.
The relevant systems or brands are Blue Water Desalination systems. The business advertises or is verified for Watermaker sales; marine equipment support; dealer enquiries. Its principal location for this directory is Mandurah WA, with practical coverage described as Mandurah and Western Australia.
A marine watermaker is a reverse-osmosis desalination plant, not simply a filter. It draws seawater through an intake and pre-filter system, raises the pressure sufficiently for the RO membrane to separate fresh product water from concentrated brine, then sends the usable water toward a test point or tank. Production depends on seawater temperature, salinity, membrane condition, feed pressure and system design, so advertised litres per hour should be treated as a rated figure rather than a guaranteed output in every anchorage.
For a dealer or broader marine business, sailors should confirm whether the company only supplies the unit or can also organise installation, commissioning and after-sales service. The difference matters because watermakers need periodic filters, freshwater flushing, membrane care and troubleshooting, and a local technician familiar with the installed system can be more valuable than the initial purchase price.

Output should be chosen from the crew's real daily water use rather than from boat length alone. Drinking and cooking may require relatively little water, while regular showers, washing machines, deck rinsing and liveaboard use can multiply consumption. A higher-output unit can shorten run time but may demand more AC or DC power. A low-energy DC system can suit a solar-heavy yacht but may need to run for many hours to fill the tanks. Owners should compare litres per hour, watts consumed, daily energy required and the capacity of the boat's battery, alternator, solar, inverter or generator system.
Installation space is equally important. Modular systems allow the membranes, filters and pumps to be separated around a machinery space, while framed systems can be easier to install and service when enough room exists. The intake should be located where it is unlikely to draw air or contaminated harbour water. The brine discharge needs a reliable route overboard. Filters, pressure gauges, flushing valves and membrane housings should remain reachable for routine maintenance rather than being buried behind permanent joinery.
Watermakers reward regular use and correct shutdown procedures. Seawater left stagnant inside a membrane system can create biological fouling, so freshwater flushing is important when the unit will sit unused. Longer lay-ups may require preservation or pickling using the manufacturer's specified process. Prefilters need routine replacement and should be checked more often in silty, plankton-rich or polluted water. Product-water quality should be monitored before water is diverted into the main tank, particularly after servicing or a long period of storage.
Owners planning remote cruising should ask which spares are sensible to carry. Typical items may include sediment filters, pump service parts, O-rings, belts or impellers, hoses and preservation chemicals, but the correct kit depends on the specific system. Membranes often last a long time when operated and maintained correctly, so replacing them simply because of age is not always necessary. Diagnosis should consider feed flow, pressure, temperature and water quality before assuming the membrane has failed.
Deen Maar (the island and adjacent coastal region off south‑west Victoria) is a small but significant offshore island and coastal protected area offering dramatic cliffs, important seabird and seal habitat, cultural values for Gunditjmara and Eastern Maar Traditional Owners, and a clear contrast between exposed Bass Strait seascape and the comparatively sheltered waters inside the Moyne/Port Fairy approaches. From the water it is best treated as an ecological and cultural landmark rather than a place for casual landings: recreational boating activity is concentrated at Port Fairy, Killarney, Y
Before your first sail in South Australian waters check the weather and tide, make sure the boat and safety equipment are fit for the trip, confirm local rules and any area-specific hazards, and tell someone your plan.

Yes — South Australian coastal waters include marine parks, aquatic reserves, harbour bylaws and local council restrictions that can affect anchoring, fishing, mooring and access; check the relevant state agencies, local councils and Notices to Mariners for location-specific rules and permit requirements.

A regular, layered maintenance routine combining hull cleaning, targeted anti-fouling management, cathodic protection and systems checks will substantially reduce marine growth and corrosion for boats kept year‑round in South Australian waters. Focus on preventing attachment and electrochemical attack, then inspect and act more often if you’re in warm, nutrient-rich or high‑traffic sheltered waters.

Choose an anchor type and size matched to your boat, seabed and expected conditions; set it by lowering steadily, backing down under power to bury the fluke or hook, and scope the rode to suit tidal range and wind/sea state. Regularly inspect your set and use trip lines or secondary anchors where risk of wind or current change is high.
