Watermakers–Ya gotta have Faith…

Posted on Sun 23 January 2011 in articles

I’m deep into my research about water makers, having met with Spectra, Hydrovane, and Village Marine yesterday at the Seattle Boat Show. I’ve also had extensive conversations with CruiseRO. You can see all the makesmodels and specifications of the units I’ve been looking at in my Watermaker Comparison spreadsheet.

The main debate I’m having with myself is DC or AC based systems. A DC based system has to run much longer to make an equivalent amount of water to an AC based system, but you can run it any time without starting a genset. An AC based system would mean running the Honda EU2000 generator anytime we want to make water including on longer passages.

This is feeling more and more like one of those faith or belief based decisions, as opposed to one that’s entirely gallonamp-hour based. One the one hand with a DC based system we have the opportunity to leverage alternative fuels (sun, wind, etc). With the Generator we’re always committed to burning gas, LPG or Natural gas. We also would be committed to managing the generator and running it on long passages (> 1week).

I’m really torn on this one… I’m hoping there’s something I’m not seeing and that you all might have some additional insight to help me make my decision.
