Bilge back-up? 1978 Columbia 26T
I am the new owner of an old 1978 Columbia 26T. The boat is in great shape and spent last winter like most sail boats in the northeast, in a boat yard on stands, beneath a tarp. Although I didn't sail her much last year, I dont remember so much water coming in the sole of the cabin via the two floor drains. These drains are merely half dollar sized holes in the fiberglass sole, which I assume empty to the bilge. The bilge is pumped out via a clever hand pump in the stbd lazarette.
I've noticed a skim coat of water on the floor when I first arrive, and when under way it grows to quite a bit more. It seems that when we are in heavy air and some good sized swells, (therefore pitching quite a bit) more water seems to enter. On a downwind run, with the nose pitched up a few degrees, it seems to drain.
Does anyone have experience with this phenomenon or Columbias in general? Any guidance would be a huge help! Thanks!
