Cosider the cost. You can buy alot of water for what the watermaker costs. The membranes have a finite life and will need to be replaced, the frequency determined primarily on hours of use. Having said that I have a Village Marine that runs on 110v. and makes 20g./hr. It has been maintenence free over 4 years. I can keep the water tank full with generator time needed to charge batteries and chill the fridge/freezer so their is no measurable fuel use to make water. In a survey done by Bluewater Sailing, the watermaker was the system that was mostlikely to give a cruiser a problem. I run any water going into my tank not from the watermaker through a carbon filter to guard against chlorine and use hydrogen peroxide as a sterilizing agent. One advantage of a watermaker not often considered is that it allows you to carry less water and more fuel on long passages as surplus water tank capacity can be turned into fuel tankage.
