lamination, the damage can be very costly, even terminal.

What is the basis for that conclusion? Personal observation? Sea
stories?


I've been around some kind of boats all my life. Before I started
having something to do with expensive motor and sailing yachts, I never
saw a blister on any old boat. That's a personal observation from over
50 years.

The part about "lamination" is also interesting, given manufacturing of
boats anyone can afford are done with a chopper gun in a mold, now, not
hand laid fiberglass for a decade or two. I don't ever remember seeing
a blister on the cheapest boats like Bayliner, but I suppose stuff
happens.

Should run faster full of blisters to roughen the surface and break
surface tension.

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.

The original question was about Bayliners. The vast majority, of not
all, have plywood transoms and stringers. Some of their bulkeads are
fibreboard.

I don't think I've seen a single sailboat hauled out in Charleston without
them. Our water is awful warm all summer and full of prehistoric critters
that bite like hell when cleaned out of the air conditioner strainers at
the dock. Any marina here is a massive ecosystem unto itself, dispite
everyone peeing over the side and dumping crap down the sink. The crabbing
under the dock is rated OUTSTANDING for Blue Crabs....yum...yum!
