83 Mac 25 Was doing some work today. Changing out the keel cable. while removing the bulkhead noticed a whole bunch of hoses. One was attached to pvc which ran all the way up to the bow then was attached to hose again then to what appears to be a seacock. Figured it had something to do with the so called galley. Perhaps a way of discharging gray water? Guess question is: Is there suppose to be a seacock in the bow.
