Hi AllI recently bought an Oceanis 400. I am a bit baffled with the fridge drain. It is connected to the sink drains at the seacock. The drain itself seems to be below water level and therefore will not drain by gravity. The boat is parked up at the moment so I cannot check to see if it will drain while under way. The hole may act like a venturi and suck the water out underway. Does anyone know the workings of this? Is there an online owners manual for this model?Regardsand thanks in Advancechamac
