A couple of things about the watermaker. The builder of Imagine installed a tank just for the watermaker to extract it's saltwater from. This wway there is no sucking of air, and purging of the machine.
I hate carrying cans, but I refuse to make water in anchorages, and unclear water. We would use South Beach Miami as our hub for travelling. I would never make water there, because of all the sand in the water, and who knows what is being pumped into the anchorage?
As far as taste? I think the water is tasteless, but that leaves me peace of mind!
