Reverse Osmosis Watermaker

Has anyone tried using a residential reverse osmosis system as a salt water watermaker with any success? I have second hand unit I am considering incorporating into my boat if such would be considered a viable alternative to the expensive production water makers. My plan is to pressurize the RO unit with a electric booster pump powered by a 12v inverter. New membranes are considerably cheaper for the residential units compared to production models, so I could afford a shorter working life of such. Please forgive the redundancy should question already been posed on another thread.

Residential reverse osmosis (RO) units remove a lot lower concentration of minerals than a RO unit intended for desalinization. The desalinization unit works under much higher pressures and the internal structure of the RO unit has to be made to withstand these pressures.
