Do you need a watermaker on your small boat? A Quick Guide to Desalination and Reverse Osmosis for Sailboats, Yachts and Motorboats.
There are a multitude of choices available, from small portable units, to high output models designed to service commercial ships and shore based facilities. For the average boatie, a desalinator might provide water for showering, deck washing and of course, drinking.
How it works
Maintenance and Winterising
Like anything with water, even when regularly used, a desalinator requires maintenance in the form of regular flushing. This process is taken care of in automatic models, but may require a more hands on approach for manual units. When sitting idle for longer periods (such as the winter months when the boat is unused) the watermaker needs to be put into a process called winterisation. The process for this is detailed in the installation manual, and involves flushing the machine with a special membrane storage liquid, and ensuring there is no water remaining that could collect and become stagnant. Various products are available to further assist in this process.
