Sharks are not the only concern in the cruising grounds of the world -  

so is contaminated water...

What yacht watermakers are available ?

Sometimes there are pre owned reconditioned watermakers available at this LINK

The following table is intended as a general guide, listed in order of price.

There are many desalinator ("watermaker") units ranging in size from hundreds of tons to the neat PuR 06 hand held liferaft unit. Also of note are the new generation of watermakers that use no electricity. This table includes examples of popular small devices suitable for a sailing / cruising yacht with an assumed crew of  1 - 6 persons and are listed in order of price. Note that where installation is required, the cost of installing may be considerable and in some cases could be half the cost of the unit itself in addition. Prices are US Dollars.

The inclusion or otherwise of a particular manufacturer or model is not intended to be of any significance and does not necessarily imply any endorsement or otherwise of any manufacturer or product. Trademarks & logos may be registered and are used only for identification purposes. Manufacturers can alter prices and specifications and rates of currency exchange can and do vary. Prices and performance data may be subject to change. Information supplied by the manufacturers, their agents or popular mail order sources. In most cases, postage / freight / installation costs (if applicable) and / or local taxes (if applicable) will be extra.

The output of drinking water from any desalinator will vary and is subject to numerous factors including battery voltage, engine speed, temperature and salinity of the sea, the cleanliness of the filters and the standard of maintenance. In the case of Waterlog models, output varies not with voltage or engine, but with boat speed. Good sailboat cruising speeds are assumed in the table. Engine or battery driven watermakers have a relatively unlimited power supply, however, the Waterlog must rely on whatever environmental energy is available from moment to moment to make drinking water from sea water. For example, the respected Spectra 200c will produce a mug of drinking water in about half a minute. The well known PUR80 about one and a half minutes.  A Waterlog may take three minutes or more, depending on the conditions.  All watermakers will display an output  variation of  + - 15% or more.

Power consumption: Some machines are more power efficient than others. Waterlog models use no power at all and require no installation / holes in the hull,  but need to be run for a longer time for the same number of crew. Using its optional emergency 12 V motor, the water powered Waterlog is not as power efficient when operating in emergency 12 Volt motor mode as the more expensive Spectra, for example. Having simplicity, Waterlogs are reliable. The Spectra energy recovery system is also noteworthy for its innovation, as is the miniscule hand held emergency liferaft unit, PuR Survivor 06.

Cost: Many yacht watermakers are scaled down versions of industrial units. There are costs involved in remanufacturing units for use on a yacht and this is often reflected in the purchase price. There are some notable exceptions where the unit was obviously designed from the outset for emergency or cruising use. Examples include the Pur 06,  Waterlog,  Katadyn 160,  Spectra 200, etc.
