I wonder if the movement / vibration in the hull induced by the act of sailing or motoring, could reduce the friction ("stiction") in the sensor. In calm flow, with nothing to help the little prop go round, it might therefore underread.

Perhaps test it by applying something like an electric drill body to the area near the sensor ?
