I would drill a few holes (a hole cutter
would give a better look) where the surveyor
said were most damp, and maybe also where he said were dry(er?) to compare and to verify his findings. The bonus from using a hole cutter
is you get to see how thick the fibreglass actually is (and how well stuck to the core!)......but before doing that, if he says the deck
all the same all over I would suspect operator error (or he is trying to get his cousin's boatyard some work!).
If the test pieces come out all wet and crumbly then you do
have a problem
. If not, I would then move into the realms of more pondering. possibly for much longer!
One "cheat" might be larger backing plates
on the cleats
and the shrouds (if not fixed to the hull). possibly very much larger!.....and maybe a few more layers of fibreglass on deck
. maybe. As I write I can feel Minarets eyes on me. Rolling
, albeit probably mixed with a sense of relief that his core
(geddit?!) business will not be stopping anytime soon from folks who have bought boats with "innovative" solutions to decks installed by PO's..........
