Thanks for the "confirmation," I'm suspecting that is what's going on. The only likely culprits are the anchor locker pan, the two starboard bow-pulpit stanchions, or the cleat, if that's the case. Did you make a repair on your 25+?I noticed a similar void at the edge of the cabin top balsa core on the 25+. The material wasn't beveled and the fiberglass of the bottom skin couldn't contour around the 90 degree edge. This created a triangular shaped void along the edge of the core. Any water that got in this area was free to travel the length of the void. It looks like that's what's happening on your boat in pic 3. Hopefully you can find the source further up hill. Maybe the anchor locker lid latch hole, a spinnaker down hull block, or one of the other stanchion bases.
