I commend you for your commitment to your product and your customers. I had intended on getting a 12 volt watermaker system until talking with you at the boat show. I have never regretted getting an AC system. Many friends run their 12 volt units for several hours to fill the tank, while monitoring/augmenting battery amps. That is a lot of wear on the components for a little water. One friend recently missed an outing with friends in the San Blas Islands because he had to stay aboard and run his 8 gph DC watermaker for several hours to fill his tanks. We did a passage with them, and it seemed that the sound of the watermaker was nearly constant during daylight hours, while underway. I never run mine for more than an hour, getting the amps from the main engine, my Honda generator, or shorepower. I have made more than 1000 gallons of water so far, with only 37 hours of run time.
