Photo #12 /13 (similar, only 13 posted) views the portside sink. "Sink with fridge under. Sink drain elbow is pointing the wrong way. It will go directly forward to the main bulkhead, then down the main bulkhead on an angle to exit the hull just below the waterline. The whole drain will be encased in the fridge insulation. There will be a seacock at the sink end, doing away with the need for a sink plug. It would have to be turned off when hard pressed on a starboard tack to stop water climbing up into the sink."
