k1vsk is correct. The condensate pan in our boat sits about 1 inch above the sole. The sink in the head is approx. 30 inches above the sole. The only options are to let it drain into the bilge and pump it out occasionally when the level gets high enough to activate the automatic bilge pump, or to suck it out with a venturi device.
Also, in our boat, the gravity drain to the bilge was unreliable and only drained about 1/2 of the water in the condensate pan, and even then, only when the pan was almost full enough to overflow. When we left the dock and went sailing, the heeling of the boat drained the rest of the water all over the inside of the cabinet and it leaked out around the joint between the cabinet and the sole, leaving puddles on the surface of the sole. The admiral was not amused by this.
So, venturi device was the way to go.
