<p>I'm planning for a long cruise in my small yacht. The water tank in the yacht has enough clean water to drink, but not quite enough for showers, cleaning the dishes etc.. </p>

<p>Desalinating ocean water during the cruise sounds like a great idea. And I can get by with only <strong>most</strong> of the salt gone for many of my uses (like showering, cleaning, toilet use..) . Is there a device that can remove salt from ocean waters? I have electricity or petrol available. </p>

<p>I know there are huge watermaking machines for big yachts like <a href="https://www.westmarine.com/buy/village-marine-tec--lt-1800-watermaker-1800gpd-semi-modular-220-60-12-v-hz-amp--12791810?recordNum=9" rel="noreferrer">this one </a>, but I need something smaller.</p>
