At the risk of being a worry-wart----all of us know how fiberglass cracks over time. It can't be helped. I have a used 1988 Macgregor 26d and it has a few cracks here and there in the fiberglass. But when it is quiet and I walk on the deck or in the cockpit, I hear the occaisional crackle or snap of fiberglass under foot. Of course there is no visible cracking, but nonetheless, I can't help but picture hairline cracks forming which will eventually turn into larger cracks... I'm sure that this noise is nothing more than say, the creaking noise you hear when walking accross a wooden floor at night. But don't you too wonder in the back of your mind? Anyone have any comments about this?
