A slight sidetrack here: I have two 100 gallon water tanks, but I want an "emergency" manual water maker for the abandon-ship bag. Now, as I understand it, watermakers want to make water in order for the membranes to stay in working order. I don't mind manual bilge pumping, I prefer manual windlass operation, I'm installing foot pumps for head and galley, and I don't mind keeping the tanks topped with manual watermaker water.
You get the picture: Electric operation if necessary, but not necessarily electric operation.
Which SMALL watermaker is appropriate for low-volume water making and could be thrown into a go-bag in a step-up-and-off situation? I picture something I could mount in the galley, give 40 strokes and get a sinkfull of rinse water. Cruisers need more exercise, anyway.
