I love a good debate... I was in the professional boat building industry
for a good number of years and comparing a boat hull to industrial GRP is
totally different. The blistering on FRP hulls can be eliminated and has been in
many cases. Blistering is the result of water intrusion into the laminate and
bacteria growth inside the laminate. How did the water enter the
laminate??? sometimes it is a dry lay up allowing the water to wick into
the laminate, in other cases it the result of an impact but in 99% of blister
problems it is merely cosmetic.
The navy still uses grp on its big boomers
(although not part of the pressure hulls) and declassified information on GRP
poly thread spheres tested for the us navy has been released. The spheres were
tested to 20,000 feet (8,889 psi) haven't seen the tech info on it yet but if
they can withstand this type of depth, well I don't think i need to say
more......
