Next message: Brian Conrad: "Suggestions Wanted for Surviving Winter on a Mooring"
Dennis, I had a '69 30' Pearson on the Chesapeake a few years ago with
the same hull issue. ( No Compression though). The surveyor found a
little moisture as well. It had been on the hard for about 6 months,
and then I had it through the winter. I sanded off the old bottom
paint, and there was the fine lines, particularly near the bow where the
keel started (it was full keel). I put on the recommended coats of
Interlux 1000 & 2000. And then two coats of bottom paint. The boat
seemed to do fine. I never checked the moisture afterward, but didn't
see any problems. Last I heard she was still afloat and 5 years older
than your perspective lady<g>
Take care
Paul
