I just had my new to me 2006 3200 sandblasted to remove all the old paint and much to my surprise uncovered hundreds or possibly thousands of small 1/8-1/4 inch blisters near the waterline and and 24 3/4 inch blisters across the transom. I called tiara asking why this could happen because I thought with there use of vinylester resins that blisters would not be a problem. They were not much help saying that the boat left the factory without a barrier coat and only bottom paint and who knows what the previous two owners did with it. It has only been in lake Erie and Lake Michigan and always in heated storage for the winter. My plan is to open up all blisters and allow to dry for a couple of months then use the interlux system of epiglass followed by  watertite filler and finally four coats of  interprotect 2000. All of this after I just spent almost 10k to repair the severely rotted hardtop due to improper initial mounting of the open array radar. At least I knew about the top before taking ownership. The blisters were not noted on the survey so that came as a total surprise. Sorry for rant!
What I would like to know has anyone else had a issue with blisters on there tiara or pursuit and what did they do to address them. Thanks for any help or advise on how to deal with this issue.

Take a breath, my friend. Hull blisters are like pimples on your behind...everyone has 'em and no one (for the most part ) can see them...so who cares.
If you want to learn more about hull blisters, google any Hatteras owners forum, as all Hatteras yachts built in the 80's suffered from them.
First- You have nothing to worry about. The hull is a solid core. No wood or coring so no worry about water intrusion.
Second- If you try and "repair", you are only going to be chasing your tail, as they will reappear in spots that look ok now.

My advice: Sand it, coat it, paint it and find something else to worry about.

Sorry to hear about your problem. My 1988 31' Open never had a blister and spent it's whole life in Florida waters. My present 1988 36 Convertible never had one either. I had the bottom soda blasted to the original gelcoat and there was not a single blister.
Both boats were in the water year round. Perhaps Tiara changed their formula.

I stripped the bottom of my 43 open after I purchased it and found some minor blistering, mainly at waterline level. The cost to have the voids filled and get a clean bottom wasn't that much plus I figured some surveyor was going to catch it whenever I do sell the boat.

4 or more coats of a good barrier coat should keep future blisters at bay.
