Long ago with full boats and kids we planned to get water in the BVI everyday whether we needed it or not just to make water not and issue. We have also gone 14 days off Belize and other places with the water and ice we left the charter dock with. Once we started using watermakers the stress and hassles that came with worrying about water went away. Just the knowledge we can make 20 gallons of water in a couple of hours made life more pleasant. No two boats are the same and some installations are better than others. That is why a good briefing is so important. In my world now if we are charging batteries we are probably making water. If everyone starts moving towards the showers and the galley. The watermaker gets flipped on at the same time making water while we are using water. Before you leave the dock understand your set up and when you have the power available to use the watermaker.

One way to control water use. Make sure everyone starting with the suspected largest water user gets to hold the hose to fill the tank. In most cases one turn holding the hose turns the high user into the water police.
