Need some watermaker advice.....
Ok, I'm looking at water makers. Sometimes it's hard to plow through the marketing hype to understand what is truly important and what is just BS. For those of you who have water makers....what do you like/recommend?
Do you prefer them belted off your main engine (the least attractive option in my mind) 12/24v powered or driven by a AC motor off the genset?
Some companies offer very fancy units with all kids of automatic dodads, scales, all manner of things. How important is this stuff?
What about capacity? How much water should a fella be able to make in a day or hour? Is it better to run a large unit for a short period of time or a small unit for a long time?
I've even read about units you make yourself in your garage...very basic, no frills kind of units....but are they too basic?
Please do tell me what you think!
Much thanks and Regards,
TJ

I am going to build my own, the website has clear instructions and should be able to make what is necessary for a cruiser with a small crew. One of my considerations is making enough water while running the genset during the recharge and other AC generation cycles in a 24 hour period.

Thanks Jack. How are you going to power this puppy? I'm very interested in how you plan to set the unit up.
Regards,

I think with a 2.5hp 110 vac motor, have not got into the actual specs yet. I am about a year from this project. Fairing the hull is next.

The smaller 12V Pur units and the like do not usually have high salinity detection & divert. If a mabrane or seal is faulty this can lead to contamination of your water tanks. I would seriously recommend whatever solution you chose has this feature.
If you are sailing in areas where you are likely to enter freshwater, estuaries or cross rivermouths I would definitely have a high product water flow alarm/shutdown fitted. The effect of trying to make fresh water out of nearly freshwater is to force too much product through the membrane as there will be very little brine to discharge. The result is a ruptured membrane. Very expensive.

I am rebuilding a Stevens 47 that had some hull damage. Just finished peeling the bottom gel coat, reapplying epoxy. I have removed a good portion of the interior. Expanding the diesel capacity to 150 g. All new systems, hatches, port-lights, toe rail the list goes on. Mostly building out of epoxy and Vectorply QuadX or BiaX
