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.
