I have just cut 2 holes in the deck of my 6 year old and the ply was very damp. It did not even scorch during pauses with the router when cutting the holes. Deck construction is 1/2" marine ply with 3-4mm GRP on top and a good coat of resin on the underside. There is no sign (yet - fingers crossed) of any softness or rot. If anyone wants an 8" dia. sample it's in my bin.
Reason for cutting one of the holes :- to fit a bilge pump to get the water out from under the deck. Now all I have to do is find a way of stopping it running in down the control cables, wires and pipes!!!
I now have a hatch each end of the deck and during this dry weather they are both open to let a bit of air circulate. I am also thinking of rigging a fan to force air thro' as well. Hopefully this will lengthen the life somewhat.
