I was just wondering if after having the irritating problem that is osmosis on my last boat if anyone has ever come across it on a parker.
My parker 27 certainly does not but i am thinking of not taking it out of the water for a couple of years so just wondering if they are susceptible to osmosis or not.

Not heard of a Parker getting osmosis ( hope no one will correct me on this) but I have had one of the earliest Parkers (Elsa, 26 no 103) from new (1982).
I rarely take her out of the water for longer than a weekend each year for antifouling.
No problems yet.
Chris.
