Brief progress report. Together with Breezin' (#454), Blue J has been moved to a warehouse where we can work on them. We were supposed to have heat, but that is another issue.
I've cut more inner hull and exposed more wet balsa. A larger cut inside the transom exposed some more rot and just wet balsa. I'm surprised that the balsa at the top of the transom was very wet -- I still think there must be other sources of water which must be sealed or this effort will be all for nought. I also removed the propane locker drain from the transom -- rotted all around, so there's another source, anyway. Note -- the outer skin appears to be thicker than the inner.
We were attempting to map the hulls with a moisture meter, and just for "calibration", put the meter next to the drain hole -- it showed green (OK). It also showed green in areas where I got very wet core samples, and red on Breezin' in a couple areas near the centerline which are solid glass. We concluded that core samples are the only reliable indicator.
Continuing to try to dry things out with a small cabin heater and trouble light, stategically placed. Using a probe-type moisture meter, the areas I exposed last month are completely dry, and those opened last weekend still show some moisture.
Looks like drying will take a long time.
