I know everyone is just trying to be helpful which is what makes this a great place. I know that Squid has done a lot of research on this and actually read these articles on blister repair (posted earlier): Hull Blisters on Boats and Yachts - by David Pascoe, Marine Surveyor
and: Sea Lake Yacht Sales (Kemah, TX)
(posted by Brian/Mitiempo)
written by surveyors with quite a bit of experience in hull blisters.
If you guys and gals read the articles you will find that neither surveyor has a high degree of confidence in conventional blister repair techniques recommended by most boat yards. Can any of you say that you have heard of, seen, or experienced a blister repair job that was effective and lasting, whatever the method?
Squiddo is in Wisconsin and wants to sail his boat this summer during the short sailing season. I can't blame him. Given the likelyhood of eventual failure of the patches (no matter what method or materials) I'd be thinking of using the cheapest, quickest method (polyester) to fair the bottom and go sailing - hoping the patches last a year or two before needing to be readdressed.
I've seen it time and time again on my boat and on other boats in my yard. The owner diligently applies an epoxy patch to the keel or hull and in a few years that same patch needs to be redone. Faulty method you say? Perhaps, or perhaps that is just the way it is.
I hope I'm wrong as my friends Endeavor 32' got a case of the blisters after being left in the water in the Chesapeake for 5 years. One hundred twenty dime sized blisters in that thin laminate would make Squidd's hull look pretty good.
Anyone know of a sure fire method for fixing blisters? Anyone?
Didn't think so. Conventional wisdom is so... conventional.
