WATERMAKERS FOR SAILBOATS AND YACHTS

WATERMAKERS FOR SAILBOATS AND YACHTS

A watermaker is essential in any trip to desalinate seawater turning it into drinking fresh water. Access to drinking water is vital when we embark and it is essential to have a watermaker for sailboat or a watermaker for yachts of excellent quality that guarantees the supply on board. Especially if we want to anchor in a cove and have no intention of going to port, the watermaker will provide us with total autonomy.

 

HOW DOES IT WORK?
The system has two seawater pumps. The first one is the feed pump, which works at a pressure of 1.5 bars approx. This pump feeds the secondary pump that is the high pressure pump that works at about 60 bars. This pressure passes through the membrane containers, with the sea membranes inside, carrying out reverse osmosis and obtaining as a result, on one hand the drinking fresh water and on the other the brackish water of rejection to the sea.

 

WATERMAKERS FOR COMPETITIONS AND RACES
When it comes to a competition, it is desirable that the watermaker adapts to extreme conditions. It is best to decide on a small, lightweight and compact model that is easy to use and can be easily repaired in the event of a breakdown, as damage to the watermaker can leave you out of the competition.

Drinking water also guarantees food. In long distance competitions it is common to use freeze-dried food, which must be hydrated. Then, the choice of a good watermaker is essential for the success of the boat trip.
In a race and also alone, it is essential to take 100% health care with the diet and use of healthy and quality water that avoids possible complications (colitis, etc.). If we store the water produced in a tank, no matter how pure it leaves the system, it is very possible that it gets contaminated in an enclosed space subjected to heat and humidity. That is why we must always consume the water produced by a watermaker instantly to ensure its optimal condition. Ultraviolet sterilizers can also be used.

It is advisable to choose a low energy watermaker, such as the Spectra brand watermakers, with the Clark energy recovery pump. The Spectra brand remains the favorite choice in major races such as Volvo Ocean Race and Clipper Challenge around-the-world. A Clark energy recovery pump will produce a minimum of 24 liters/hour, with consumptions around 108 Watts or 4.5 Watts per liter produced. This type of pumps are in their favor a very low energy consumption but, on the other hand, there is a greater work of friction and wear between the internal parts. In contrast, a high-pressure pump with hydraulic pistons and oil lubrication involves less friction and wear work on internal parts, but has much higher consumption of between 2000 and 2500 Watts to produce the same amount of water.
