[C320-list] Head Vent

That is amazing, my 1997 hull 424 vents about 2 feet to the stern of the lower starboard window. I have replace the line and know it is a direct vent.

Obviously with the wire running through it there is only a small annular area for the air to pass it so the flow will not be great -  but then it doesn't really have to be great as the holding tank is plastic and will thus take some small expansion temporarily (acting as a gas accumulator really!) and then the excess pressure can disperse over time through the stanchion?
