I’m going to have to say it was an oversight by Parker and most likely the void was left half assed or just not adequate.Id want to know how it's getting so wet too. Doesn't appear that your bilge is staying wet. I guess it's hard to see but was the fiberglass not completely sealing the wood stringer? A little disappointing if that was the case. Does your boat stay in the water or live on a trailer? It really looks like poor craftsmanship but I think your plan will work fine, at least give you plenty breathing room until you decide to to do a more thorough repair. I woudl think you would still want to cover it with some fiberglass to prevent future intrusion of water. That's a damn shame and looks preventable.
Boat is trailer sailed, cover at all times with plug removed bilge hatch always left agar, as well as bow hatch. To my dismay it was discovered like a previous posted, brown tannin colored staining resembling a rust spot.
The wood appears solid a few inches from entry point, but it has disintegrated by the void so where it’s a hollow shell from my examination with a pick tool.
I let it sit under heat for 5 hours and it seeped water. The wood already appears drier if that possible.
A glass man wants to tear my boat apart and I’m so sad to have to do it, I kept up with this thing and knowing there’s a rotten stringer at worst is enough to get me paranoid. Love this hull, and have had almost zero issues with construction, but this issue appears to be mostly caused by manufacturing failure or lack of product quality assurance. It looks too much like a void to me, however bashing a 20 year old hull is pointless.
Time will tell, I can fish and use it as is, but it will drive me crazy thinking that it’s rotting beneath my feet, as they say ignorance is sometimes bliss. Shouldn’t have poked my head around down there, now I gotta a problem I can’t walk away from
