1979 Catalina 27. it seems I have a very slow trickle of water creeping into my bilge area at the far aft end about a foot past the last keel bolt. when i completely dry out the bilge area with a towel, the ever small trickle is visible. It may only be a quart per day, but it adds up fast. Has anyone experienced this, and if so, can it be repaired from the INSIDE? I'm guessing it may require a haul out to allow it to dry out, but still not sure. any replys welcome.
