This is the BEST solution I've ever seen for a liveaboard
who doesn't visit docks.
We decided against the watermaker, figuring 140gals of water was enough. As it turns out... it is... almost. We can make it a month on that amount of water (dirty, filthy sailing scum!). ha ha ha
But seriously, water is our limiting factor. We are looking to build a watermaker this winter, but unfortunately already have a great generator. If I were starting from scratch, I would do exactly what Bob did below. It's the most reliable and efficient way to go.
are great, but you'll always need that backup generator and diesel for the inboard. So... why not use the "backup" generator to do everything you need?
Since we have a diesel genset already, my watermaker will be 120VAC powered, off that main power plant.
For the original poster: You are left with a lower GPH watermaker if you run the DC models off of whatever DC charging you anticipate. This just means a longer petrol genest run, or expensive solar/wind. This is another advantage of just biting the bullet and getting an AC genset. It will run many types of inexpensive non-marine appliances
. If you get a really powerful one, you only need to run it 1 hr per day to use computers
, house loads AND watermakers. It's extremely efficient.
