Mine runs to a through hull just slightly right (looking into the
locker) of directly below the sink.
The downside to this, is that it is in the way when accessing the dip
stick for the 2QM engine and
the exhaust drain for winterizing. I re-routed the down route a bit to
give me more space.
I wouldn't really see an issue in routing to the cockpit drain, it is
nearby and handy, and likely
resolves some of the access issues above.

Hello All
I have a C&C 30 Mk 1, a fine old boat that has a history of different
owners. Recently, we had a very cold snap with temperatures hitting
the – 12to – 16 range. A good stress test for the boat’s plumbing for
sure. To make a long story short, I need to know how the galley sink
drainage ought to be configured on this boat. You can read more for
detail, or simply respond. All information will be appreciated.
…. In the aftermath of the cold snap, I found that there was some
seepage from the galley sink. And there I found an odd configuration.
The 1.5-inch drain was stepped down to a 1-inch diameter hose that ran
into the drainage for the cockpit. There a Y fitting was screwed into
the seacock (a 1.5-inch diameter) that allowed the 1-inch drainage
from the sink to drain into that seacock. The lip onto which the
1-inch sink drain line attached itself was pitifully short—about 1
inch, and below the water line. Not very safe and a configuration that
can not fully drain the sink.
The upshot is that I have to change the galley sink drainage system.
The C&C 30 Mk 1 owners manual gives no details on this—but it does
show that the cockpit and galley sink drainage are separate systems.
The local chandlery folk advise me to install a new drainage
thru-hull (with a gate valve) between the bottom of the sink and the
waterline, to ensure that it drains properly. But this is a wide
margin leaving me without a precise idea of where to put the
thru-hull. And I am not sure whether I need an elbow under the
sink--or how that ought to be configured.
Can anyone tell me how the gally sink drainage was handled by C&C at
the outset. Are there any specs or design principles that I could use
to help me pinpoint these positions or design the new system?
Your help will be appreciated.
Best, Alex Netherton
