Mystery leak CD25

[Ron Musk]

78 CD25 has been plagued by slow leak that keeps bilge under cabin floor wet.Auto pump handles accumulated water,cycles on once every 48 hrs. or so,removes a couple gals. each time.Can find no evidence of water entering anywhere inside hull.Grounding plate on keel is well sealed and tight.Rudder post fittings look sound and are greased annually,although lower fitting shows some discoloration around it.Anyone with similar problem and or suggestions? comments appreciated.

Ron: on the 1980 models of the CD25, the bilge hand pump, located in the starboard locker has a hose that runs from the pump along the locker into the boat itself and down into the bilge. But from the same pump there runs another hose that goes back to the thruhull where the water from the bilge exits the boat. That smaller hose may be loose, and the source of the leak is very hard to find, because you can not see it. Get your hand as far down as you can following the natural path of that hose to your thruhull and by feeling it, you will know if the water is coming from there. my old 1980 CD25 swamped twice due to that problem, and I could never find the source. Only after I sold the boat to the new owner, he discovered the problem and was able to fix it. This may be your case. Good luck.

We have found that water gets into boats through a wide variety of means. This has been true of both rainwater and sea water above the water line. At various times, we have seen the water seeping down from under the liner into the bilge. We have also seen a lot of condensation. I am guessing that most of the non-condensation water comes through bedding that has aged at all the various points. There are also some sources that are a function of design, such as the companionway hatch or vents.

In most cases, we have been happy to look at the still water in our bilge and left it there until it got excessinve. On our previous CD25, we ususally got concerned when it could reach into the lockers under the berths while heeling.

Hope this helps.
