I never have read of bistering being a problem on newer boats (like newer than 1985).
In walking the boat yard in the winter the only ones I see with any blistering issues are older boats. So whether they "fixed" it I don't know but it doesn't look to be an issue overall.

Don't expect an answer, seakingbubba. This thread is from 2008, and the OP has not posted since then.

SollaSollew, how do you like your Bavaria? (if you still have it)

Vinylester resins reduce the possibility of osmosis, but AFAIK, they do not remove it altogether. Even an epoxy barrier coat, which is probably a bit more substantial than your tie coat won't necessarily prevent osmotic blistering.

Blistering on Modern Boats
I have a 2006 Bavaria which, I believe, was fabricated with Vinyl Ester resin. From the Bavaria Website:
"A layer of isophtal acid resin in combination with a powder bound matt of glasfiber avoids the diffusion of water and obviates damage by osmosis."
I routinely keep the boat in the water year round (except for Spring short haul). An epoxy 'tie-coat' was applied to the yacht on delivery (mostly so the bottom paint would stick). Is osmotic blistering still an issue or did the chemists solve this problem years ago.
