Re: Blistering left unchecked?
I read alot about it a couple of years ago, and was only able to track down one single hull, that was structurally compromised due to blisters.
The reason given, was that the used types of mats in the layup was completely wrong.
As I understood it at the time, on a correctly build boat, it can never get deeper than the first couple of layers after the gelcoat.
My slip neighbour has a boat from the early 80'es and it is really really bad with blisters. When they remove the gelcoat, you can see glass completely void of any resin. But they are never more than 1-2 mm deep. So I think they have stopped fighting it, and they sail A LOT.
