Re: Mid 80's Blisters

My 1986 PSC37 had a hundred or so dime sized blisters. I Let her dry out for a year and had them ground out, epoxied and barrier coated in Mazatlan 3 years ago. On my recent careen, I noticed that some more had appeared but did not count them, just painted her and let the tide come back in. The boat is in warm tropical waters all the time.

Re: Mid 80's Blisters

FWIW - Jo Beth is a 1984 34, and spent the first 17 years of her life in warm, tropical waters. When we bought her in '03, she had three blisters, all dime sized close to the keel; two on one side and one on the other. We've done nothing to remedy them, and to be honest, I don't recall seeing them on the last haul out.

We've had her in GA waters since taking possession of her. Water temps in our marina basin can vary from stupid warm in the summer, 90+ degrees in the summer to mildly cool, in the mid-low 60's or upper 50's in the winter.

Of course, there is the possibility we'll haul her and have an epidemic, but so far, so good. A diver just scrubbed the bottom last weekend and mentioned nothing.

Re: Mid 80's Blisters

I had blisters..I made them go away..

If they come back ...which I doubt...I'll make them go away again...

Re: Mid 80's Blisters

Scupper: I have a 1983 Pacific Seacraft 37. When pulled for the survey it had hundreds of blisters. I bit the bullet and bought the boat anyway after also doing a lot of reading about blisters and alternatives to repair. In the end I thought "have you ever heard of a boat that sank due to blisters?" Really it comes down to resale value.
When it came to repair the Yard was really pushing for me to do the high end $$$$ repair where you remove layers of laminate. I opted for sandblasting then repairing any individual blisters that remained. Cost was around $10K. So far so good. So if you buy the boat make sure wthey come down on the price so you can do the blister repair.
I really liked this article:

Re: Mid 80's Blisters

I feel and many many others may also feel blisters are not very often a deal breaker.

My boat had water line blisters. and a dozen, dozen or so, on the bottom not many, when we took it down to gel coat most were gone.. some.. not many needed digging out and filling.. 3 yrs now and the barrier coat seems stable.

The key word was "likely". It doesn't mean "impossible". It's a chance that you take.

Our boat had a couple but I didn't sweat it. Our last Sabre developed a bunch when we left the boat in the water over a winter. I fixed them and always hauled after that... Never saw another blister on the boat.

Re: Mid 80's Blisters

I've been going through the Archives page by page and reading everything pertinent or just down right interesting. I'm up to page 13 out of 30 something. So far I've only found one boat that has lots and a few others that seem to have taken effective measures to cure the problem before it got too bad. Is the search feature at the top of the page the most effective way to glean information from the archive? I'm hoping that the, "If it doesn't have them by now, they are unlikely to form", advice is good advice. Thanks for everybody's input. I guess I just have big cash anxiety!

Re: Mid 80's Blisters

Hi Scup,
Have you tried searching the PSC archives for blisters. With such an active forum, not much discussion would indicate that it is not a common problem.

Blisters are specific to the boat and while the cause is still not fully understood, it appears related to quality control (both materials and construction) during the build.

As indicated, you need to look at this specific boat. If it doesn't have them by now, they are unlikely to form. Pulling a boat each season and allowing it to fully dry over the winter definitely helps alleviate or prevent blistering.

Re: Mid 80's Blisters

I guess I am trying to find if there were any years that were particularly bad.
