Government mandated blisters. Was the years they made them for Viet Nam
and added a fire retardant to the resins.


Ironically, it wasn't until the mid 70's that the blisters started showing
up on recreational boats. My father-in-law's was a '72 and was a
recreational version of one of the Vietnam era patrol gunboats (except the
military ones had jet drives instead of props). The fiberglass was rough
due to minimal upkeep, but there were no blisters.

The Uniflite Mega that I had was a '78 or '79. (I forget which) It had
blisters on the topsides, but none that we ever noticed below the waterline.
