[C320-list] Phantom leak

[Bronwen Young]

Our 1995 C320, FanaSea #198, has an interesting leak.  When we are in the slip, there is no leak.  When we go out for a sail and heal over we get water into the cross brace tubes (but, not into the regular bilge).  We have closed all the through hull valves except the large one that discharges the head directly into the lake (it is seized, have to wait until she is on the hard to work it free as the whole holding tank area is below water line).  There does not seem to be a leak at the base of the goose neck up by the Y valve.  Glad for any ideas, or if anyone has ever had a similar experience.    Cheers, Bronwen
