No. But I have done a lot with them.
In its simplest form it should not be too dificult, the only parts you would have to buy is the membrane around 3-400 euros each depending on how much capacity you want. You could make a pressure vessel depending on your facilities and you will have to buy either a Clarke type pump or a Cat pump (used in car washes) to provide the high pressure feed (900 psi) - if you mount this below the w/l you can get away without a feed pump. The flow rates can be got from google as I cant remember them off the top of my head. A restriction valve and, a pressure gauge and a flow gauge and you are done.

You will of course need a lot more bits than that but thats the basics

It would be a project thats for sure. Be carefull with 900psi water though - blow the end cap off your pressure vessel and it could go through you or the side of your boat!

Good luck with it

Paul

The American magazine "Good Old Boat" Jan/Feb 2003 which I was given recently has a whole article on building your own water maker. If you pm me your address I will photocopy it and send it to you.

I am currently installing a DIY watermaker in my yacht in durban (south africa)
the membrane and pressure vessel was supplied to me by a frend. The pressure vessel made in SA but the membrane imported. The outout is approx 80 lt/hour and is either mains electricty driven of belt driven from main engine. I have mine mains driven and have fitted a mains alternator belt driven from my main engine. PM me with contact details and I can help with supply of parts you cannot get in namibia.
