no electric water maker

[Jocelyne]

has anyone tried those no electric water maker type, one manufacture drags it behind the boat and use the instruments own prop to pump the water. some brands use a hand pump

I've tried the Hand Pump on my "PUR-35" watermaker (12VDC c/w "hand" pump option). I'd suggest it's only a "survival" device - not meant to make domestic water. Pump for ever, get very little product in return.

Most R/O units require very high pressure, so I'd be leary of the towing watermaker. It's probably not effective.
Do you have a link to any specific product(s), I could examine?
