A boat watermaker is essential on any voyage to desalinize seawater, turning it into fresh drinking water. Access to drinking water is vital when we embark and it is essential to have a water purifier for sailboat or a water purifier for yacht of excellent quality that guarantees the supply on board. Especially if we want to anchor in a cove and we do not intend to go to port, the seawater purification plant will give us complete autonomy.

The system has two seawater pumps. The first is the feed pump , which works at a pressure of approx. 1.5 bars. This pump feeds the secondary pump or high pressure pump that works at approx. 60 bars. This pressure passes through the membrane containers, with the sea membranes inside, carrying out reverse osmosis and obtaining fresh water on one side and brackish water rejected to the sea on the other.

When it comes to a competition, it is desirable that the watermaker adapt to extreme conditions. The best thing is that you decide on a small, light and compact model, which is easy to use and can be easily repaired in the event of a breakdown, since damage to the water purifier can leave you out of the competition.

Drinking water also guarantees food. In long-distance competitions, the use of freeze-dried food is frequent, which must be hydrated. For all this, choosing a good sailboat water purifier is essential for the success of the journey.

In a regatta and also alone, it is essential to take care of your health 100% with food and the use of healthy, quality water that avoids possible complications (colitis, etc.). If we store the water produced in a tank, no matter how filtered it leaves the system, it is very possible that it becomes contaminated in a closed space and subjected to heat and humidity. That is why we must always consume the water produced by a water treatment plant instantly to guarantee its optimal state. Ultraviolet sterilizers can also be used.

It is advisable to choose a seawater purifier with low energy consumption , such as the Spectra brand purifiers, with the Clark energy recovery pump. The Spectra brand continues to be the favorite choice in major regattas such as the Volvo Ocean Race and Clipper Challenge around-the-world. A Clark energy recovery pump will produce a minimum of 24 litres/hour, with consumption around 108 Watts or 4.5 Watts per liter produced. These types of pumps have a very low energy consumption in their favor but, on the other hand, there is more friction and wear between the internal parts. On the other hand, a high-pressure pump with hydraulic pistons and oil lubrication entails less friction work and wear on internal parts but has much higher consumption of between 2,000 and 2,500 Watts to produce the same amount of water.
