In a previous thread, there was discussion that when a saltwater boat is moved to fresh water, Tim Reilley said that osmotic blisters can appear and you will not find them for a while. http://www.ericsonyachts.org/infoexchange/showthread.php?t=9309
I'm looking at a saltwater boat (being surveyed this week) with a few small blisters just below the water line that C.O. says have been there but with no change for several years. He said the boat was barrier coated prior to his purchase 10 years ago and the bottom was painted last year. Not sure if I understand the processes, but would the move to fresh water, in effect, encourage these blisters to grow or reveal additional blisters that are not current visible? Even if stable so far, would you recommend repairing the blisters before it is put in fresh water?
A related issue is whether a fresh bottom paint job for saltwater is OK fresh water?
Thans for your input. I've read about but never owned a former saltwater boat.
