Plenty of water
An abundance of fresh water is a real luxury in a salty environment - and you can get it on board. Watermaker systems and installation at a glance

Around two decades ago, watermakers were a luxury that only a few long-distance sailors on full-size yachts could afford. The systems were regarded as power guzzlers and very vulnerable.
Today, hardly any yacht is sailing without a watermaker; the systems have become cheaper and more reliable - and demands have risen.

  The salt water is sucked in by the feed pump and passes through two to three pre-filters (coarse filter, sediment filter with 5 and 20 micrometres) before it reaches the high-pressure pump. The filters are connected to the pressurised water system via a valve so that they can be flushedPhoto: Johannes Erdmann The salt water is sucked in by the feed pump and passes through two to three pre-filters (coarse filter, sediment filter with 5 and 20 micrometres) before it reaches the high-pressure pump.

What could be better than having plenty of fresh water available in a salty environment? The Watermaker creates independence and the luxury of not having to constantly check the water tank level when planning your route.

  The salt water is channelled along the membrane at high pressure. The water molecules migrate to the inside of the membrane and are fed into the drinking water tank via the blue hosePhoto: Johannes Erdmann The salt water is channelled along the membrane at high pressure.

When dimensioning the watermaker, it is important to ask yourself the following questions in advance: How much power is required? What purpose should the watermaker serve? Emergency, daily use or luxury? How much space is available on board? Is only a compact unit an option, a modular system or a complete unit? How do I operate the system? By producing my own electricity with solar and wind, via the diesel engine or via a generator?

You can read tips on dimensioning, correct installation and what to look out for to ensure reliable operation of the watermaker in the new YACHT 20/2020 - now available at newsagents, order here or as a digital edition.
