Screw holes usually show in wood decks as dimples where the wood has absorbed water
except where compressed by the screw.
If the core
is wet you need to dry it. Otherwise you may have mold
showing up where the moisture tries to get out.
If the plywood deck
is damp. How do you dry it?
I have a plywood/teak deck
and have just spent over 200 man hours replacing the jib
sheet tracks. That was because I found about a desert spoon full of water
that had come from one of the track bolts. After removing the track found corrosion
on the underside so decided to replace them. The original holes were 3" centres and the new tracks 4" centres. 47 fixing holes in each track. I bored all the old holes out to 5/8 and filled them with Mega Poxy epoxy
glue. Then marked out all the new holes and filled them using the same method then drilled through that for the fixing bolts. Also a backing under the deck was replaced. I also countersunk the holes and sealed the underside of the tracks and the holes with butyl tape.
I think that since the tracks probably had minor leaking through those other bolt holes the plywood
may be damp or have a higher percentage of water than should be. I decided to carry on with the job and see if anything happens. Of course I'm interested in drying them.
I think my decks will outlast me. If not, I'm going to remove it all and fit plywood / Dynel decks without teak
and just Kiwi Grip.
A 50 ft cruiser seems a huge job so good luck with it.
