Open Ocean Watermakers

The Best Of Both Worlds


​There are simple watermakers and there are complex watermakers.  Complex watermakers have a bunch of sensors and switches which allow for easy operation.  The trade-off is reliability.  When the salt water exposed sensors fail, the system becomes unworkable.  Simple systems have the advantage of no sensors to fail, but they can be complicated to operate, with various valves to operate in what are often inconvenient locations.

With our Quencher systems, we have married the ease of operation of the complex systems with the simplicity and reliability of the simple systems.  The hands-on controls mean you always know exactly what is going on with your system (there are no mystery cycles). The small control panel can be fitted in an easy to operate location.  A reliable watermaker no longer means running from locker to bilge to run the system.

​We have been building watermakers since 2001.  Located in Opua, in the Bay of Islands, we combine quality components with a simple design.  As cruising sailors, we know the value of having a system that you can count on.  Our systems are largely made up of off-the-shelf components that are available almost anywhere in the world.


Choosing a system for your boat

We offer 4 different drive options for our systems, AC, DC, Engine Drive, and Hydraulic.  We also offer an all manual control panel system that is suitable for installation in a service area, or a manual/electric control panel that is suitable for installation in the cabin.  That makes 8 basic systems, with a number of options for each.

Should you be running the main engine for any purpose, then the most efficient way to make water is with an Engine Drive high pressure pump. Fresh water production is very high, ranging from 80 litres to 240 litres per hour.  The challenge with the Engine Drive system is installing the high pressure pump.  Some boats do not have engine spaces that make installing a power take-off on the engine a simple matter, but for those that do, Engine Drive is a great choice.  Cruising boats that have an Engine Drive watermaker often find they make all of the water they need, without running the engine just to make water.

The 240-120 Volt systems offer an easy installation solution with water production between 80 and 240 litres per hour.  Ideal for boats that are running 4.5+ kW generators.

Our 12 and 24 Volt High Output systems are a good fit for boats with very large solar arrays, or no renewable power at all.  These versatile systems can be run from alternator power, battery charger (through your generator), or from a large (1000 Watt plus) solar array.  Highly versatile and easy to fit, these systems produce a nominal 70 litres of fresh water per hour.
