I think too much is made of "wet decks" all to often. As we discussed the other day many surveyors have never even seen the internal results of what a 30%+ reading looks like on a JR Overseas moisture meter.
If I find wet readings I sound them very carefully. The soundings will often tell you more about core condition than will a simple moisture reading on its own. The two must always be combined to make an educated decision on whether to repair or leave it alone.
If the core still sounds out similar to an area that is known to be dry, simply stop the ingress of water and leave it alone if it's in a non-critical area. A dorade box on most boats is usually a non-critical load area and if it sounds out fine but has higher than normal readings then I'd personally leave it and continue to monitor it with soundings and moisture readings..
Areas around stanchions, masts, chain plates, cleats and bulkheads are under loads than an area under a dorade box and are areas I would address asap if they did not sound out well and gave dull thuds..
Usually when the meter pegs, this is considerably higher than a 30% reading, you will find the balsa to begin to be discolored. If it has been saturated long enough it will look like coffee grounds but will feel mushy under foot as well. Even when damp to moderately wet the balsa will still be well bonded. There are very few boats out there without some areas of wetness.
You can do wither two things here. 1) remove and re-lam the top skins and fix it well or 2) Fill and fair over the holes you've made and live with it. If it was me I'd want to re-lam after I'd gone this far.
If you need to borrow my Multi-Master let me know via PM. I'll be home from this business trip on Sat. All I ask is that you bring it back with good working sharp blades..
