I have a 1980 C25. In the bilge, right under the swing keel winch, there is a pipe of about 1" diameter running forward out of the bilge, glassed in alongside the CB trunk. Can anyone tell me what this pipe is for, and where it leads? I'm fighting numerous water leaks, all from above the waterline, I think (hope!). I bailed a lot of water out of the bilge, and found that more water kept coming in through this pipe. The water does not smell nor taste like salt water, so I'm fairly certain it's not coming in through a hull breach. Thanks in advance,Jack
