Hey Bob I bought one of those fancy nondestructive moisture meters so I can track the water intrusion sources pretty easily.
That rear bulkhead with the door all water came up from where it attached to the floor. We had resealed that attach point over and over, but at times water would come in from the rear deck into the cabin underneath and balsa we couldn’t see was exposed. It is dry near the windows.
You are spot on for the anchor line locker source. I previously paid somebody to go into the anchor locker to dig out the wet core there. The water was coming from the drain hole and and winch eye. The part I’m working on now is where the water wicked further down below into the tunnel and then froze in winter and popped through the glass inside.
So far all of the interior laminate seems to be 1/8“, two layers of 1708, which I believe counts as four, layers gets me the same thickness.
If I had a new tomcat, (hint, hint) I would pull the winch point, remove the anchor drain clamshell cover and do the epoxy re-bed on all core intrusions in this area! Some of that core was so wet and rotten it wasn’t even attached to the laminate anymore.
I hadn’t mentioned previously, but we already had to replace ALL the bottom core bow to stern in both sides. Yes, even under the head. $25,000 for that job. That’s a bigger story than I have time for now
