That's a brilliant article Christal. I think it's the clearest and most convincing one I've ever read, for the first time I thought 'Ah ha - Yes, I understand that now'. I'm surprised though that the person who sold you Seaventure thinks it supports the popping and leaving of blisters? The way I read it, it says the opposite? According to that article, popping the blister would relieve the osmotic pressure, but it would then allow uninhibited hydrolysis of the resins in the hull which would lead to an accelerated weakening of the hull structure?
Another thing that struck me in that article was that it said that this weakening by hydrolysis could potentially result in faster failure of hulls with core construction, and once the core is saturated it is usually economically unviable to repair the boat. .... the Krogen 38 is of core construction, but the core is closed cell PVC foam though so can't become saturated in the first place? I'm assuming the article is referring to boats with a balsa core?
It's disheartening knowing that having a boat in the water is resulting in a relentless gradual weakening if its hull, but I guess it's just something that has to be accepted - with GRP boats it's hydrolysis of resins, wood it's rot, steel it's .... well hydrolysis again I suppose (metal salts & water? is that hydrolysis?). ... but with all of them there are remedies, wood: new planks, GRP: new laminate, steel: new plates. We are lucky with the Krogen 38 that the hull is no darned thick in the first place - Modern GRP boats certainly aren't built that way. The surveyor who did our pre-sales survey told us that he thought Elsa was built in the days before manufacturers started doing the sums to calculate just exactly what they could get away with in the lay up.
They were still thinking about quality & safety
Anyway, whichever way you look at it there's no escape from entropy, just an endless battle against it, with boats, houses, gardens, roads, flood defenses etc etc ... Hull blisters are just more of the same.
