I don't ever remember seeing
a blister on the cheapest boats like Bayliner, but I suppose stuff
happens.

They typically fail from stringer or transom rot, sometimes decks,
floors or bulkheads.



Once again, we're all showing our ages by assuming, wrongly I believe, that
there ARE stringers and wooden transoms, which I don't think is the case
any more with that chopper gun spraying into the mold. When I was watching
him do it, here, I didn't see any wood to rot at all!

They were wood when we had that wonderful hand laid fiberglass we were
taught was of such high quality....which it obviously wasn't as it rotted.

Plenty of boats are hand-laid glass.
The lowly Mac 26 for one.
They still have balsa too, I think, but there are boats now using
non-rotting composites for transoms/stringers.
Ranger for one, I believe, maybe Carolina Skiff.
Chopper-guns are avoided by quality boat makers.
It pays to know how any boat you're considering was put together.
Balsa/plywood rot is a hell of a lot more serious problem than
blisters.
That's what I've read, anyway. Never saw a boat blister in person.
